The basic premise of the game is that the player has to solve increasingly difficult puzzles. There are 16 levels, and the amount of points needed in order to beat the puzzle increases. By beating all 16 levels and unlocking certain achievements or completing certain challenges, players can unlock different characters (VTubers), outfits, and abilities (that come with different characters and/or outfits). Players start off with a random Hand, which is a set of 14 tiles. There are 5 sets in a “valid” Hand, where 4 of them are either triplets or sequences, and the last one being a pair; there are a few exceptions to this, however. Players go through a cycle of beating a puzzle and buying tiles and/or jokers to improve their score, eventually getting to the final boss, after which, if they beat it, have completed a run.
