* TheComputerIsALyingBastard: [[VideoGame/{{Arcaea}} "Red and Blue and Green"]]'s Lunatic chart has a difficulty rating of 0. Anyone who takes this difficulty rating at face value will be InstantlyProvenWrong, as it's just as hard as other Lunatic charts.

The core gameplay features a panel with two sets of three face buttons, with one set on the left and the other on the right, a large analog joystick in the center that can be moved horizontally, and two buttons on the inner walls of the cabinet. The player controls a party of three on a "hallway" perspective as they scroll down the chart. Upon reaching red, green, and blue notes, the player must hit the corresponding color of button (doesn't matter which side of buttons you hit, at least until a certain point in the difficulty scale). Likewise, there will be purple notes on the edges of the lanes; these must be hit with the correct button. Finally, the player uses the stick to move their team, in order to collect yellow Bell items for bonus points and health, avoid pink and purple bullets that will damage the lifebar when hit, and keep their team on the lanes whenever they narrow and twist, because if the player goes off-course, they will be unable to hit any notes.

** First, there is what the game simply calls Score, which is based not only on how well you hit notes but also how powerful your team's cards are.

* WeWinBecauseYouDidnt: Reaching the end of the song without defeating the boss results in a draw rather than winning outright. This is still much better than a loss, which is caused by running out of health (from hitting too many bullets) and which cuts the song short, depriving you of a lot of potential jewels, Score, and most importantly, Technical Score.

Unlike other arcade rhythm games, which typically give the player a fixed number of songs per credit, this game uses a GP system. Inserting credits adds GP and inserting multiple credits may grant the player bonus GP, depending on operator settings. Playing a song uses up a set amount of GP, as does extending the pre-song menu timer. After every song, the player can choose to keep going provided they have enough GP for another song or the money to buy-in extra GP, or end their session and convert unused GP into Money, a currency used for various features.

* SurplusDamageBonus: Upon defeating the song's boss, the song will keep going but you will start to rack up an Over Damage bonus, which can net additonal gems.

In addition to all of this, each song has an associated enemy team you face off against. Hitting notes will deal damage to the current enemy character in proportion to how accurate the note was hit and the strength of the player's team. If the player runs out of health, [[GameOver the song ends prematurely and they lose]]. If they deplete the enemy's health, another member of the enemy team will take their place; once the entire enemy team is wiped out and provided the player doesn't [[DoubleKnockout fail out too]] along the way, the player wins. Otherwise, the song ends in a draw. Playing songs will level up the team members' affection and experience levels, allowing them to stand better chances against tougher enemy characters.

''O.N.G.E.K.I.'' (オンゲキ) is a RhythmGame with BulletHell elements for UsefulNotes/{{arcade|Game}}s published and developed by Creator/{{SEGA}}, using their ALL.Net infrastructure for network features. It was originally released in 2018, as the third game to be released in SEGA's ''VideoGame/{{Performai}}'' series, after ''VideoGame/{{maimai}}'' and ''VideoGame/{{CHUNITHM}}''.

** Second, there is Technical Score, which is a more conventional system that is based only on your performance (cards have no impact). Up to 950,000 points can be earned from hitting notes, and the remaining 60,000 is earned from collecting Bells, for a maximum score of 1,010,000 points (i.e. [[Over100PercentCompletion 101%]]). This is notable for a game with a gacha system, as mobile rhythm games with gacha elements typically have ''only'' card-based score in order to encourage players to mass-roll for rare cards as a tradeoff for being free-to-start.[[note]]Whereas in this game, even if you don't use the gacha at all and just focus on the rhythm game aspect, you're still paying to play the game, so pulls or not, you're making revenue for the arcade and the publisher.[[/note]]

** Finally, some modes in ''R.E.D.'' use the Platinum Score system. A new judge rank, Platinum Critical Break (or simply Platinum Break), is added and which is worth more than a regular Critical Break. Platinum Breaks add 2 points, Critical Breaks add 1 point, Breaks, Hits, Misses and collecting Bells are worth nothing, and taking damage or missing bells ''takes away'' 2 points.

* HarderThanHard: Master above Expert, just like the other two games in the series. ''O.N.G.E.K.I.''[='=]s iteration of Master difficulty is notable in that while the lower difficulties only have three lanes of notes that can be activated by face buttons on either side, Master charts can have ''six'' lanes; during the six-lane segments you have to use the correct side to get credit.
