Groove Coaster

There are various targets in the game. The command required will differ, depending on the target.

Tap (Hit in AC version)

A circle-shaped target.

When the avatar reaches it, tap the screen. In arcade version, hit either button on the BOOSTERS.

Some Hit notes will jump in from outside of the course line.

Hold

A circle-shaped target, followed by a colored line traced on the course line.

When the avatar reaches it, tap and hold the screen until the end of the target. In the arcade version, press and hold either button on the BOOSTERS.

Beat

A target that contains a certain number of diamond-shaped dots chained together on the course line. The Beat target won't appear in EASY/SIMPLE mode.

When the avatar reaches it, tap the screen rapidly until the end of the target. In arcade version, tap the button on both BOOSTERS rapidly.

Scratch

A circle-shaped target, followed by a colored spiral line behind. The Scratch target won't appear in EASY/SIMPLE mode.

When the avatar reaches it, rub the screen as fast as possible until the end of the target. In arcade version, move the controller back and forth rapidly, without switching BOOSTERs.

Flick (Slide in arcade versions)

A diamond-shaped target attached with an arrow. The Flick target won't appear in EASY/SIMPLE mode.

When the avatar reaches it, flick the screen into the direction where the arrow points at. In arcade version, move either BOOSTER into the direction where the arrow points at.

Like Hit notes, some Flick notes will jump in from outside of the course line.

AD-LIB

There are invisible targets called "AD-LIBs". If the player hit the AD-LIB successfully (at least GOOD judgment), "AD-LIB" will be shown beside your avatar and bonus points will be rewarded. It won't count as a MISS if the player misses the AD-LIBs. However, if the player wants to get FULL CHAIN status for the stage, the player has to hit all the targets and AD-LIBs successfully. If any AD-LIB is missed but all the targets are successfully hit, it will be a NO MISS status.

If the player hits the button when no targets around but doesn't hit any AD-LIB, it's a blank hit and a different sound will be heard. A blank hit doesn't affect the play score, but it will affect the reward in multiplayer match.

In the arcade version, new targets are added.

Dual Tap (Critical in arcade version)

A target with a dot surround by an eight-angle star, noticeably bigger than the Hit target.

When the avatar reaches it in 2OS, tap the screen with two fingers, and in the arcade version, hit both BOOSTER buttons at the same time.

Like Hit notes, some Dual Tap notes will jump in from outside of the course line.

Dual Hold

A target that starts with a Critical target, followed by two colored lines behind. The Dual Hold target won't appear in EASY/SIMPLE mode.

When the avatar reaches it, tap the screen and hold it with two fingers until the end of the target.

In arcade version, press and hold both BOOSTER buttons until the end of the target.

Dual Flick (Dual Slide in arcade version)

A target with two Flick / Slide targets combined. The Dual Flick target won't appear in EASY/SIMPLE mode.

When the avatar reaches it, flick the screen with two fingers to the directions the arrows point at, at the same time.

In arcade version, move both BOOSTERs into two directions the arrows point at.

If there is a Dual Flick with arrows that point in a similar direction, moving both BOOSTERS in the same direction will suffice.

Like the Slide target, some Dual Slide notes will jump in from outside of the course line.

Slide Hold

A target that starts with a Flick/Slide target, followed by a thick trail behind. The Flick Hold target won't appear in EASY/SIMPLE mode.

When the avatar reaches it, flick the screen into the direction where the arrow points at, and hold it until the end of the target.

In arcade version, move either BOOSTER into the direction where the arrow points at, and hold it until the end of the target.

In arcade version since 3LF, if the player managed to clear the stage with full score of 1,000,000, a special clear status, PERFECT, will be rewarded to the player for the stage.

Note: To unlock all the unlockable contents in arcade version, a NESiCA IC Card is necessary.

The Unlock Key system is introduced in arcade version since ver. 4.02. After each play, the player receives 1 to 2 keys, depending on the mode they're playing. The player can receive one extra key each time they play the designated song, usually the one chosen for events. The keys can be used to unlock various contents.

Songs

In iOS version, the songs are automatically added into selection as the player levels up.

In arcade version, most of the songs that are unlockable can be unlocked by using Keys, while some of them can be unlocked by achieving certain conditions.

Avatar

New Avatar will be automatically added as the player levels up.

In arcade version, the player can also gets new avatars by completing certain requirements for Events.

Items

There are various items players can select before playing the song. Each item has its own effects on the stages.

Only a type item can be used per stage. Extra EXP points ("GROOVE COINs" in arcade version since 2HF) will be rewarded when the player clears a stage with certain items.

In arcade version since 2HF, due to the "LEVEL" system replaced by "GROOVE COIN" system, some items were replaced into something else. The player can now buy most of the items at the ITEM SHOP in MYPAGE, though some of the items are unavailable to buy and must be unlocked by using Keys.

Item	Effect Description	iOS Version	ZERO	Arcade Version	EX	2HF	2OS	3LF	3EXDP	4SR
FOLLOW / SAFE	Covers a MISS up to GOOD for 10 times. SAFE is shown beside the avatar when the effect is activated. (However, the GOODs covered by FOLLOW / SAFE are worth no points.)	(FOLLOW)	(FOLLOW)	(SAFE)	(SAFE)	(SAFE)	(FOLLOW)	(SAFE)	(SAFE)	(SAFE)
FLICK CHANGE	Converts Flick targets or some special long notes into Taps. However, this will drastically deplete your maximum score.

Skin

When a target is successfully hit, visual effects are displayed.

Usually the visual effect is default, but the player can change the effect before playing a song by selecting Skins.

New Skins will be automatically added into selection as the player levels up. In 2HF, the player can buy Skins with "GROOVE COINs" in Skin Shop at MyPage of Groove Coaster.

Title (Arcade version only)

The player can set the title when selecting Avatars.

New titles will be rewarded as the player completes certain achievements.

The player can also acquire new titles according to the performance of the Events.

(However, the songs released under Game Music Triangle and AOU are not available for this system)

Certain Avatars, Songs, and Title can be unlocked with a big enough number of Trophies.

• There were more than 150 songs in this version, including in-app purchases and those as part of limited-time events.
• A difficulty rating of 10 was added.
• Copyrighted songs, including Vocaloid songs, were added. Copyrighted songs with no artist have been placed under the category J-POP.

Launched on July 1, 2015, for free on both iOS and Android devices.

On iOS, this app replaces Groove Coaster Zero in the form of an update, and as a result it is impossible to have Zero and 2OS on the same device.

On Android, this is the first Groove Coaster title to be released for the platform.

A 3,000,000 downloads campaign started in August.

• The ability to use multiple fingers has been added, as opposed to allowing just one finger at a time, as was the case in all previous versions. Faster touch gestures are now easier to pull off.
  • To correspond with this, most songs now have Arcade Mode added, bringing three additional difficulties made to be played with two fingers (in total, EASY, NORMAL, HARD, AC-EASY, AC-NORMAL, and AC-HARD). Songs with a grayed-out AC label lack Arcade Mode, but may have it in the future. Songs with a blue AC label have Arcade Mode.
  • In Arcade Mode, the highest difficulty rating has been raised to 20.
  • If a song pack that now has Arcade Mode has been purchased in Groove Coaster Zero, Arcade Mode will become available to play after a $0.99 in-app purchase.

  • Calculation for the final score of any given track in Arcade Mode now copies the arcade version scoring.
• Original Style has been added, which allows players to use their device's microphone input to make sounds to play the game. As all targets are converted to Taps in this mode, your score will not be recorded, but still allows you to level up after playing.

• By meeting set conditions while playing, items, titles, avatars, and even new tracks can be obtained as rewards through the Mission screen.
• 2D avatars are now in full color.
• Setting certain options are now possible, including:
  • Performance (can be changed by indicating whether or not improvisation and Ad-lib sounds are played and whether or not chain visual effects are displayed)
  • Lag adjustment for sound and visuals
  • Lag adjustment for correct gesture judgement and input
  • Microphone sensitivity adjustment for Original Style
• When the 3,000,000 downloads campaign started, the maximum level players can reach has been raised yet again, this time from 200 to 300.

Groove Coaster arcade machine

Launched on November 5, 2013. The machine is a dedicated housing with a 55-inch liquid crystal monitor.

• Taito's arcade save data service, NESiCA, can save players' play records and track data. The app version is incompatible with the arcade version.
• Titles have been introduced, which are displayed in the leaderboards for bragging rights.
• Unlike on mobile devices, the arcade version is controlled by two controllers called Boosters. The Boosters themselves have one button at the top of each of them, and they are also made to be tilted, similar to a joystick, with the whole hand. This reproduces the Taps or Flicks from the mobile versions. In addition the names of targets have been changed from Tap to Hit and from Flick to Slide. Both Boosters are able to be used at the same time.
• A headphone jack and volume control dial can be found between the Boosters.
• Just before a track starts, instructions on how use the Boosters for each target type in that track are displayed.
• Upon reaching a Chain of 100, the FEVER status from previous versions will become TRANCE, increasing the Chain by four for every target successfully.
• Score calculation has been overhauled. The new scoring systems works as follows:
  • The PLAY SCORE encompasses the player's main score in the level before the results screen. In a playthrough with all GREATs and a FULL CHAIN, this score will max out at 850,000 points.
  • The CHAIN SCORE is based on how much of the FULL CHAIN is completed during the track. As such, a FULL CHAIN will make this score max out at 100,000 points.
  • Lastly, a 50,000 point CLEAR BONUS is earned for simply clearing the track.
  • All of these will add up to 1,000,000 points, a perfect score. Ranks of E, D, C, B, A, or S are awarded based on this score.
• One credit would allow two tracks to be played. Failing tracks does not result in a game over.
  • On January 10, 2014, one credit would allow three tracks to be played.
• Multiplayer with up to 4 players is supported. Score is not the determining factor in whether players win or lose, but rather by stars earned by meeting certain criteria during the track.
• Songs are sorted into five genres: J-POP, VOCALOID, GAME, VARIETY, and ORIGINAL.

The player can start the play in multiplayer mode. Once a player starts recruiting, a 90-second countdown will start. Other players (up to three more, which can make a four-player match) can join the match before the countdown ends. The recruiting player can also end the recruitment by pressing the BOOSTER button.

Stage selecting is almost the same as single-player mode. Any player can decide the song that will be played in the match. Each player selects their own mode, items, and skins. However, EXTRA mode selecting goes differently. If the songs that contain EXTRA mode were selected by the player that has already unlocked the mode, then all the players can select EXTRA mode. If not, then only the player who has already unlocked the mode can select it.

The system will recruit players from all over the world. Usually, the match begins when the fourth player is recruited. However, a two- or three-player match will be triggered if the system cannot find enough players in a period of time.

Each player selects the song they want to play in a set list. When all players finish selecting, the system will select a song from the players' choices via roulette. The players then select their own mode, items, and skins. The EXTRA mode will be unavailable if the player has not yet unlocked it.

In the stage, the player's own avatar is shown on the course line, while other players are shown beside it. Also, the player's own rank is shown right below the avatar.[8] As the stage progresses, the relative position of the players' avatars will differ, depending on their own play scores.

When the stage ends, a match result screen will be shown. From 2, the player competes with each other with total number of stars earned from three tunes. The player with the most stars wins the match. In 3LF, for some rewards, the star given to players will increase in later Tunes, making the game easier to be reversed if any mistake is made. Also the number of stars the player gets in Online Matching will become Battle Point reward, which can be used to compete with others in the Event. Playing in multiplayer mode lets the player receive bonus EXP reward (GC reward in 2) and one extra "MUSIC PANEL".
