{{Nihongo|'''Grinding'''<ref>{{Cite manual |game=Sonic and the Black Knight |system=Wii |region=European |page=7}}</ref>|グラインド|Guraindo}} is a move that appears in the [[Sonic the Hedgehog series|''Sonic the Hedgehog'' series]]. It is a technique that encompasses the act of balancing on and moving down a [[Grind Rail]].

==Description==
Grinding is the act of balancing on a [[Grind Rail]] and then moving down such rails at high speeds. Most practitioners grind with their shoes on the Grind Rails while others grind using other parts of their bodies, like their rear. Some [[Extreme Gear]] also come with the ability to grind, while others require the [[Grind Skill]] [[Gear Part]] to possess said feature.

In gameplay, grinding is used by the player to move down Grind Rails. By doing this, the playable characters can gain more speed/momentum while grinding, usually by performing a specific action, typically [[boost]]ing. In addition, the playable characters' speed will be maintained when and after grinding. Through grinding, the player can also take shortcuts or obligatory paths made up of Grind Rails through the levels. Grinding is typically as fast as or faster than running. Sometimes, while grinding, the player can also pull off special actions. 

To start grinding in gameplay, all the player (normally) has to do is touch a Grind Rail. In some games however, the player is required to perform a certain action in order to interact with the Grind Rails.

==Game appearances==
===''Sonic Adventure 2''===
In ''[[Sonic Adventure 2]]'' and its enhanced port ''[[Sonic Adventure 2: Battle]]'', grinding is a technique that [[Sonic the Hedgehog|Sonic]] and [[Shadow the Hedgehog|Shadow]] can use. However, in multiplayer, [[Amy Rose]] and [[Metal Sonic]] can use it as well. Grinding is relatively difficult in this game due to the fact that the Grind Rails are thin and do not "attract" the player when they approach them. 

[[File:GSNP8P-130.png|thumb|225px|left|[[Sonic the Hedgehog|Sonic]] grinding down a [[Grind Rail]], from ''[[Sonic Adventure 2: Battle]]''.]]
In gameplay, the player can [[crouch (grinding)|crouch]] to achieve higher grinding speed. However, crouching may do the opposite if the playable characters are not properly balanced or are leaning too far on one side of the Grind Rail. While grinding, the player also has to use the control stick to help the playable characters balance on the Grind Rails, which is important as not doing so will significantly reduce one's grinding speed or cause the playable characters to fall off the Grind Rail. The player can also jump between parallel Grind Rails while grinding with the [[Grind Step]].

Some Grind Rails in the game allow the player to finish grinding with a trick; by pressing {{A Button (Dreamcast)}} at the end of these Grind Rails, the character performs a trick that can be worth 200, 500, or 1000 [[point]]s (Shadow occasionally gets a close-up on his body doing the trick). There is also a special [[Grind Race]] in two-player mode in ''Sonic Adventure 2: Battle''.

Both Sonic and Shadow wear customized shoes, the [[Grind Shoes]] and [[Air Shoes]] respectively, that are suitable for grinding.<ref name="SC">{{Cite web|author=[[Sega/Sega of America|Sega of America]]|publisher=[[Sega]]|url=http://www.sega.com/sonic/homepage.php|title=Sonic Central|date=March 2007|quote='''Darrell C''': Why did you change your shoes in Sonic Adventure 2 Battle? / '''Sonic''': Those were special shoes that were specifically made for grinding. It was something that I've always wanted to try and it sure came in handy! Look forward for some more intense and extreme grinding in my next adventure, Sonic Heroes.}}</ref> Grinding is an essential element in this game, and is not only useful for cutting time off one's record, but is also necessary for crossing certain paths in [[zone|stages]]. It is also used as a mechanism by which to aid in defeating more difficult foes.

===''Sonic Advance'' series===
====''Sonic Advance''====
{|align="left"
|[[file:Adv sonic grind.gif|left]]

|[[file:Adv amy grind.gif|left]]
|}
In ''[[Sonic Advance]]'', the grinding technique was featured for the first time in a 2D game. In this game, only [[Sonic the Hedgehog|Sonic]] and [[Amy Rose|Amy]] are capable of grinding. When grinding, Sonic grinds with his sneakers while Amy grinds on her rear. 

In gameplay, to start grinding on the Grind Rails, the player must first jump onto the flat portion of the Grind Rails at the beginning. Sonic and Amy will then begin grinding down the Grind Rails. Also, pressing in the opposite direction the grinding playable characters are heading in with {{Directional Pad}} will cause them to slow down. Conversely, pressing in the direction the grinding characters are heading in with {{Directional Pad}} will cause them to speed up.

Grind Rails in the game also allow the player to finish grinding with a trick by pressing {{A Button (GBA)}} at the end of these Grind Rails.

====''Sonic Advance 2''====

[[File:GrindingAdvance2.png|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from ''[[Sonic Advance 2]]''.]]
In ''[[Sonic Advance 2]]'', the grinding maneuver is available to all five playable characters. In gameplay, grinding is now fully automatic, meaning that simply jumping onto the Grind Rail will result in grinding. In addition, [[Amy Rose|Amy]] grinds with her boots rather than her rear, something which she would do in all future games from then on.

Like ''[[Sonic Advance]]'', the Grind Rails allow the player to finish grinding with a trick by pressing {{A Button (GBA)}} at the end of these Grind Rails, but only when playing as [[Sonic the Hedgehog|Sonic]] or Amy.

====''Sonic Advance 3''====
In ''[[Sonic Advance 3]]'', all five main playable characters in the game are capable of grinding. In gameplay, grinding works exactly like it did in ''[[Sonic Advance 2]]'', except that pressing {{A Button (GBA)}} at the end of [[Grind Rail]]s do not cause a playable character to perform a finishing trick.

===''Sonic Heroes''===
[[File:Grinding (Sonic Heroes).png|thumb|225px|left|[[Sonic the Hedgehog|Sonic]] grinding, from ''[[Sonic Heroes]]''.]]
In ''[[Sonic Heroes]]'', grinding is a technique that all playable characters can make use of. When the characters are in Fly Formation though, it is only the character on the bottom of the chain that grinds.

In gameplay, the player just has to land on the [[Grind Rail]] to start grinding. While grinding, the player has to use the control stick to help the playable characters balance on Grind Rails in order to maintain their speed. The player can also use the [[Grind Step]] to switch between parallel Grind Rails and the [[crouch (grinding)|crouch]] to increase the playable characters' acceleration while grinding (which is useful for when they are stuck at the bottom of a sloping or vertical Grind Rail). 

The speed of which the playable characters will grind depends on the player's team formation: [[Speed Type|Speed Formation]] grinds the fastest, [[Power Type|Power Formation]] grinds the second-fastest, and [[Fly Type|Fly Formation]] grinds the slowest. In addition, in Fly Formation, the playable characters do not make a noticeable trick when crouching (unlike the other team formations).

===''Sonic Rush'' series===
====''Sonic Rush''====
[[File:Leaf Storm Wait I'm A Fire Cat So....png|thumb|225px|[[Blaze the Cat|Blaze]] grinding, from ''[[Sonic Rush]]''.]]
In ''[[Sonic Rush]],'' both [[Sonic the Hedgehog|Sonic]] and [[Blaze the Cat|Blaze]] are able to grind. Gameplay-wise, the grinding maneuver works like it did in ''[[Sonic Advance 2]]'', except the player is now able to pull off [[Trick Action|Grind Tricks]] and [[Trick Action|Just Tricks]] at the end of Grind Rails (the latter which grants 400 [[point]]s) while grinding. In addition, the characters can use the [[Boost|Super Boost]]/[[Fire Boost]] move while on the Grind Rails.

====''Sonic Rush Adventure''====
[[File:Coralcave.6.JPG|150px|thumb|left|[[Blaze the Cat|Blaze]] grinding, from ''[[Sonic Rush Adventure]]''.]]
In ''[[Sonic Rush Adventure]]'', the grinding maneuver is again reserved for [[Sonic the Hedgehog|Sonic]] and [[Blaze the Cat|Blaze]]. In gameplay, the grinding mechanics are the same as in ''[[Sonic Rush]]''. Also, during the final grinding section in [[Plant Kingdom]] Act 1, the player is able to use the [[Grind Step]].

===''Shadow the Hedgehog''===
[[File:LAVASHELTER7.png|thumb|225px|right|[[Shadow the Hedgehog|Shadow]] grinding, from ''[[Shadow the Hedgehog (game)|Shadow the Hedgehog]]''.]]
In ''[[Shadow the Hedgehog (game)|Shadow the Hedgehog]]'', grinding is only useable to [[Shadow the Hedgehog|Shadow]] (and the [[Shadow Android]]s in the multiplayer). This is also the first 3D ''Sonic'' game in which no balance mechanic is used while grinding. 

In gameplay, to start grinding, all the player has to do is touch the [[Grind Rail]]. While grinding, the player can [[crouch (grinding)|crouch]] to gain an extra boost of speed and the [[Grind Step]] to jump to parallel Grind Rails. While grinding, the player can also use various [[weapons in Shadow the Hedgehog|weapons]], but they can only be aimed in the forward direction.

===''Sonic Riders'' series===
====''Sonic Riders''====
[[File:Egg Factory 02.png|thumb|225px|left|[[Amy Rose|Amy]] grinding, from ''[[Sonic Riders]]''.]]
In ''[[Sonic Riders]]'', grinding is a [[Speed Type]] maneuver. As such, only characters that are classified as Speed Types, or are equipped with a special [[Extreme Gear]] that grant the Speed Type attribute, can grind. 

In gameplay, grinding allows one to travel faster than the standard riding speed. One may only grind on a Grind Rail that starts with a blue light and ends with a red light. To connect to such a Grind Rail, the player must approach the blue light and press {{A Button (GameCube)}}/{{Cross Button (PS)}}/{{A Button (Xbox)}}. Grinding surfaces must be approached from above, so it might be necessary to first jump or make use of a ramped surface 

The player can also jump from one Grind Rail to another by jumping off at the red point and then pressing {{A Button (GameCube)}}/{{Cross Button (PS)}}/{{A Button (Xbox)}} while near a Grind Rail with a blue point. For every jump between Grind Rails the player makes, they earn one "link". While grinding, the player will also receive extra [[Air]]. The more links the player makes, the more Air they will receive.

====''Sonic Riders: Zero Gravity''====
[[File:Megalo Station 16.png|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from ''[[Sonic Riders: Zero Gravity]]''.]]
In ''[[Sonic Riders: Zero Gravity]]'', the users of the grinding maneuver depend on the [[Extreme Gear]] they use rather than the character. This means only characters equipped with Skate-type Gear, or Gear with the [[Grind Skill|Grind]] [[Gear Part]], are able to utilize Grind Areas. Skate-type Gear allows grinding by default while the Grind Gear Parts must be activated manually after collecting a certain amount of [[Ring]]s.

In gameplay, grinding allows one to travel faster than the standard riding speed. Like in ''Sonic Riders'', one can only grind on edges that glow blue at the start and red at the end. To start grinding on a suitable Grind Area, the player has to press one of the following buttons while close to the start of a Grind Area:
{|class="wikitable" style="text-align:center"
!rowspan="2"|[[PlayStation 2|PS2]]
!colspan="3"|[[Wii]]
|-
!Wii Remote<br/>(vertical)
!Wii Remote<br/>(sideways)
!GameCube controller
|-
|{{Cross Button (PS)}}
|{{A Button (Wii/DS)}}
|{{2 Button (Wii)}}
|{{A Button (GameCube)}}
|}

When encountering a split in the Grind Areas, the player can simply jump across them to continue grinding, earning one "link" in the process. While grinding in this game, the player also earns [[Gravity Point]]s. The more links the player makes, the more Gravity Points they will receive.

====''Sonic Free Riders''====
[[File:Screenlg12.jpg|thumb|225px|left|[[Sonic the Hedgehog|Sonic]] grinding, from ''[[Sonic Free Riders]]''.]]
In ''[[Sonic Free Riders]]'', every character is capable of utilizing the grinding technique, as long as their [[Extreme Gear]] is equipped with the [[Grind Skill]] [[Gear Part]], or they are using the [[Omnitempus]]. The Grind Skill Gear Part can be activated at any time the player pleases.

In gameplay, grinding allows the player to travel faster than the standard riding speed. Like in the previous titles in the [[Sonic Riders series|''Sonic Riders'' series]], grinding edges are marked with a blue glow at the start and a red glow at the end. To get on a Grind Rail and start grinding, the player must either cross over a Grind Rail, jump onto a Grind Rail, or reach a Grind Rail by successfully performing an [[Trick Action|Air Trick]]. While grinding, the player also gains more [[Air]]. Also worth noting is that the player can gain more grinding speed by accurately riding the Grind Rail by leaning left and right to follow the curves (as per the game's Kinetic controls).

===''Sonic the Hedgehog'' (2006)===
[[File:WVOSONIC16.png|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from [[Sonic the Hedgehog (2006)|''Sonic the Hedgehog'' (2006)]].]]
In [[Sonic the Hedgehog (2006)|''Sonic the Hedgehog'' (2006)]], the grinding maneuver is a technique usable by every playable character, although only [[Sonic the Hedgehog|Sonic]], [[Blaze the Cat|Blaze]], [[Shadow the Hedgehog|Shadow]], [[Miles "Tails" Prower|Tails]] and [[E-123 Omega|Omega]] encounter grind rails during gameplay. During multiplayer, [[Silver the Hedgehog|Silver]] also encounters them. This game also marks the first time since ''[[Sonic Adventure 2]]'' where sparks fly from the Grind Rail as the character grinds on it.

In gameplay, the player can start grinding by just landing on a Grind Rail. The grinding mechanic was also given widely different behavior compared to previous games. In this game, a character's maximum grinding speed and acceleration is predetermined, although it can be sped up slightly by [[crouch (grinding)|crouching]]. In addition, the player can now target the Grind Rails with the [[Homing Attack]], thus allowing the player to zoom towards a Grind Rail and instantly grind on it, although the player can only target the middle of the Grind Rails rather than the ends. Also, starting from this game, merely jumping onto a Grind Rail will accelerate the player to a high grinding speed.

Interestingly enough, the game contains unused grinding animations for Sonic for leaning both left and right, similar to ''[[Sonic Adventure 2]].''

===''Sonic Rivals'' series===
====''Sonic Rivals''====
[[File:Sonic-rivals-20061025041948757 640w.jpg|thumb|225px|left|[[Shadow the Hedgehog|Shadow]] grinding, from ''[[Sonic Rivals]]''.]]
In ''[[Sonic Rivals]]'', the grinding maneuver is used by all five playable characters in the game. In gameplay, the characters can start grinding by just landing on the Grind Rail. When grinding, the characters automatically accelerate to top speed. Also, by pressing {{Directional Pad Down}} + {{Cross Button (PS)}}, the player can jump off Grind Rails.

====''Sonic Rivals 2''====
In ''[[Sonic Rivals 2]]'', all eight playable characters are able to grind. In gameplay, grinding works just like in the previous title, except the player cannot jump off the Grind Rails.

===''Sonic Storybook Series''===
====''Sonic and the Secret Rings''====
[[File:SatSR-Sand Oasis.png|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from ''[[Sonic and the Secret Rings]]''.]]
In ''[[Sonic and the Secret Rings]]'', the grinding maneuver is used only [[Sonic the Hedgehog|Sonic]]. In gameplay, Sonic can start grinding by simply landing on a [[Grind Rail|Grind Edge]]. The player can also equip Sonic with different [[Skill]]s that allow him to increase his acceleration while grinding:
*'''Quick Grind''': Using Grind increases Grind speed
*'''Fast Grind''': Increases acceleration more than with Quick Grind.
*'''Mach Grind''': Increases acceleration more than with Fast Grind.
*'''Sub M-Grind''': Maximum grind speed increases but gradually consumes [[Ring]]s when in use.

When grinding in this game, the player can [[crouch (grinding)|crouch]] to regain speed and press {{1 Button (Wii)}} to brake while Sonic grinds forward, although the latter can cause him to fall off if used severely. In addition, Sonic can jump between parallel Grind Edges using the [[Grind Step]].

====''Sonic and the Black Knight''====
[[File:Sonic-and-the-black-knight-3001.jpg|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from ''[[Sonic and the Black Knight]]''.]]
In ''[[Sonic and the Black Knight]]'', only [[Sonic the Hedgehog|Sonic]] is capable of grinding. In gameplay, Sonic can start grinding by just touching a Grind Rail. While grinding, Sonic can [[crouch (grinding)|crouch]] and swing his sword to attack targets that appear along the Grind Rails. Also, by grinding continuously, the player will earn "Grind Bonus" [[point]]s.

===''Sonic Unleashed''===
[[file:Apotos2.png|thumb|225px|left|[[Sonic the Hedgehog|Sonic]] grinding, from the [[Xbox 360]]/[[PlayStation 3]] version of ''[[Sonic Unleashed]]''.]]
In both the [[Xbox 360]]/[[PlayStation 3]] version and [[Wii]]/[[PlayStation 2]] [[Sonic Unleashed (Wii/PlayStation 2)|version]] of ''[[Sonic Unleashed]]'', the grinding maneuver can only be used by [[Sonic the Hedgehog|Sonic]] in the daytime. In gameplay, Sonic can start grinding by simply landing on the Grind Rails. The player can also use the [[Grind Step]] to switch between parallel Grind Rails and the [[Boost|Sonic Boost]] (on most Grind Rails) to accelerate while grinding.

In the Xbox 360/PlayStation 3 version of ''Sonic Unleashed'', Sonic will perform an 180 degree spin while grinding when the player presses {{Circle Button (PS)}}/{{B Button (Xbox)}}. However, this action slows Sonic down slightly rather than giving him a boost of speed.

===''Sonic Colors''===
[[File:Sonic Colors Rail.jpg|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from the [[Wii]] version of ''[[Sonic Colors]]''.]]
In the [[Wii]] version and [[Nintendo DS]] [[Sonic Colors (Nintendo DS)|version]] of ''[[Sonic Colors]]'', and the remaster ''[[Sonic Colors: Ultimate]]'', the grinding technique is used by [[Sonic the Hedgehog|Sonic]], the [[Virtual Hedgehog]]s and [[Super Sonic]]. In the original Wii version, the [[Mii]] can grind as well. In their respective games, Sonic, the Mii, and the Virtual Hedgehogs grind with their feet. When Super Sonic grinds however, he simply floats above the Grind Rails.

In gameplay on the Wii version of the game and ''Sonic Colors: Ultimate'', grinding works much like in the [[Xbox 360]]/[[PlayStation 3]] version of ''[[Sonic Unleashed]]''; the player can start grinding by jumping onto Grind Rails, accelerate while grinding by [[boost]]ing, and jump between parallel Grind Rails by [[Grind Step]]ping. Also, the player periodically earns 3,000 "Grind Bonus" [[point]]s for some time by grinding continuously.

In the [[Nintendo DS]] [[Sonic Colors (Nintendo DS)|version]] of ''Sonic Colors'', grinding is only used by Sonic. In this game, it works like in ''[[Sonic Rush]]'' and ''[[Sonic Rush Adventure]]'', but without the [[Trick Action]] system.

===''Sonic X Shadow Generations''===
====''Sonic Generations''====
[[file:Sonicgenerations3.jpg|thumb|225px|left|[[Sonic the Hedgehog|Modern Sonic]] grinding, from the console/[[PC]] version of ''[[Sonic Generations]]''.]]
In the console/[[PC]] version of ''[[Sonic Generations]]'', the grinding maneuver is used by both [[Sonic the Hedgehog|Modern Sonic]] and Classic Sonic. While Modern Sonic grinds like he has always done, Classic Sonic grinds by rolling down the top of the Grind Rails in [[Spin Attack]] form instead of standing on them (bizarrely, this still causes sparks and metallic scraping). [[Super Sonic|Modern Super Sonic]] also again grinds by floating above the Grind Rails. In gameplay, the grinding mechanics for Modern Sonic are the same as in [[Xbox 360]]/[[PlayStation 3]] version of ''[[Sonic Unleashed]]'': the player can start grinding by jumping onto Grind Rails, jump between parallel Grind Rails with the [[Grind Step]], accelerate while grinding on most Grind Rails by [[Boost]]ing, and perform an 180 degree spin by pressing {{Circle Button (PS)}}/{{B Button (Xbox)}}. However, the last action, unlike the [[crouch (grinding)|crouching]], will only slow Modern Sonic down slightly. The player can also target the Grind Rails with the [[Homing Attack]], thus allowing them to zoom towards a Grind Rail and instantly grind on it. Also worth noting is that grinding for Modern Sonic is slightly faster than running (without using the Boost).<ref>{{Cite book|title=Sonic Generations: BradyGames Official Strategy Guide|publisher=[[BradyGames]]|page=15|date=1 November 2011|isbn=978-0761555100}}</ref> For Classic Sonic, grinding occurs fully automatically once initiated.

In the [[Nintendo 3DS]] [[Sonic Generations (Nintendo 3DS)|version]] of ''Sonic Generations'', only Modern Sonic can grind since only his Acts have Grind Rails. In this game, the grinding mechanics are similar to how they were in the ''Sonic Rivals'' games; Modern Sonic can ride a Grind Rail by jumping onto it, and he can fall through a Grind Rail if the player hold {{Directional Pad Down}} + {{A Button (Wii/DS)}}/{{B Button (DS)}}. In addition to that, Modern Sonic can Boost while grinding. Also, during the final, non-Boosting grinding segment in [[Tropical Resort (Sonic Generations)|Tropical Resort]] Act 2, the player can use the [[Grind Step]].

====''Shadow Generations''====
{{Expansion}}

===''Sonic Lost World''===
[[File:New badnik, more challenge.png|thumb|225px|[[Sonic the Hedgehog|Sonic]] grinding, from the [[Wii U]] version of ''[[Sonic Lost World]]''.]]
In the [[Wii U]] version and [[PC]] [[Sonic Lost World (PC)|version]] of ''[[Sonic Lost World]]'', [[Sonic the Hedgehog|Sonic]], [[Super Sonic]] and the [[Virtual Hedgehog]]s are all capable of grinding. Like in ''[[Sonic Colors]]'', Sonic and the Virtual Hedgehogs grind while standing on Grind Rails in this game, while Super Sonic simply floats above them. Other than that, the player has no special moves or tricks associated with grinding in this game, although they can still jump between parallel Grind Rails while grinding.

In the [[Nintendo 3DS]] [[Sonic Lost World (Nintendo 3DS)|version]] of ''Sonic Lost World'', grinding is reserved for only Sonic and Super Sonic, both of whom grind by standing on the Grind Rails. In this game, unlike its console/PC counterpart, Sonic has access to the [[Grind Step]], which allows him to switch between parallel Grind Rails. In addition, the player can target the Grind Rails' ends with the [[Homing Attack]], thus allowing the player to zoom towards a Grind Rail and instantly grind on it. Also unlike the Wii U/PC version, grinding is featured in both 2.5D and 3D sections.

In both versions of the game, the player can start grinding by simply landing on the Grind Rails.

===''Sonic Forces''===
[[File:BeatAvatar.jpg|thumb|225px|The [[Avatar]] grinding, from ''[[Sonic Forces]]''.]]
In ''[[Sonic Forces]]'', the grinding maneuver is exclusive to [[Sonic the Hedgehog]], [[Super Sonic]], [[Shadow the Hedgehog]] and the [[Avatar]]. In this game, all playable characters grind with their feet on the Grind Rails, including Super Sonic.

In gameplay, grinding works much like it did in ''[[Sonic Unleashed]]''. To start grinding, all the playable character has to do is touch the top of a [[Grind Rail]]. The player can also perform both the [[Grind Step]] to switch between parallel Grind Rails and the [[Boost]] (Sonic only) to accelerate while grinding. Much like in ''[[Sonic Colors]]'', the player also earns 1,000 [[point]]s per second the playable characters are grinding.  Additionally, the player can be speed up slightly by [[Crouch (grinding)|crouching]].

===''Sonic Frontiers''===
In ''[[Sonic Frontiers]]'', grinding reappears as a technique used by [[Sonic the Hedgehog|Sonic]], [[Miles "Tails" Prower|Tails]], [[Knuckles the Echidna|Knuckles]], and [[Amy Rose|Amy]].

In gameplay, all the playable characters have to do to start griding is to jump or touch the Grind Rail, and they can use the [[Boost]] to increase their speed.

===''Sonic Superstars''===
In ''[[Sonic Superstars]]'', the player is able to grind on the vines in [[Speed Jungle Zone]].

===''Sonic Dream Team''===
{{Expansion}}

==Other game appearances==
===''Sonic Runners Adventure''===
[[File:SRAGreenHill6.jpg|thumb|225px|left|[[Shadow the Hedgehog|Shadow]] grinding, from ''[[Sonic Runners Adventure]]''.]]
In ''[[Sonic Runners Adventure]]'', all the playable characters can perform the grinding maneuver. In this game, grinding is something the characters pull off automatically during the section transitions in the levels that feature Grind Rails. During such sections, the player has no control over the characters as they grind.

===''Sonic Forces: Speed Battle''===
In ''[[Sonic Forces: Speed Battle]]'', every playable character in the game is capable of grinding. In gameplay, all the playable characters have to do to start grinding is to touch a Grind Rail. Also, upon starting to grind, the characters will move at speeds surpassing their running speeds. They are also able to jump between parallel Grind Rail by using the [[Grind Step]] while grinding. The controls while grinding remain the same, except that the characters cannot slide.

===''Sonic Speed Simulator''===
In ''[[Sonic Speed Simulator]]'', every playable character is capable of performing the grinding maneuver. In this game, all playable characters grind with their feet on the Grind Rails.

In gameplay, all the playable characters have to do to start grinding is to touch a Grind Rail. Also, while grinding, the characters will move with the exact same momentum they had when they began began grinding and jump on it without falling off.  Other than that, the player has no special moves or tricks associated with grinding in this game. However, the player's grinding speed will slowly decrease if they are moving up a slope on a Grind Rail.

In the ''[[Sonic Boom (series)|Sonic Boom]]'' series, grinding is a technique used by all members of [[Team Sonic (Sonic Boom)|Team Sonic]] and [[Shadow the Hedgehog (Sonic Boom)|Shadow]].

==Trivia== 
*In ''[[Sonic Adventure 2]]'', [[Sonic the Hedgehog|Sonic]] and [[Shadow the Hedgehog|Shadow]] wore [[Wikipedia:Soap (shoes)|Soap]] brand grinding shoes as part of a promotion for the shoe company. Later games dropped this, allowing Sonic to grind with his regular shoes.
*According to [[Sega]], the grinding mechanic's addition to the ''Sonic'' series was heavily inspired by the fact that they were working on Jet Set Radio, which originally used the mechanic, around the same time ''Sonic Adventure 2'' was in development.{{Citation needed}}
*Western manuals of ''[[Sonic Advance]]'' have incorrectly stated that the player is required to press {{R Button (GBA)}} in order to grind on Grind Rails.<ref>{{Cite manual |game=Sonic Advance |system=Game Boy Advance |region=United States |page=6}}</ref> However, this is not essential, since the player will automatically begin grinding in Grind Rails regardless in the game.
*Grinding also appears in ''[[Sonic the Hedgehog Level Pack (Lego Dimensions)|Lego Dimensions]]'' as a technique that can only be performed by Sonic and Legolas. The technique is used almost exclusively in the Sonic the Hedgehog level pack and Adventure World.
