It is raining bubbles and you need to filter them through with 3 color options but you need to change the filter's color and pass the matching colored bubbles before the whole platform fills up. The bubbles keep getting faster and faster until the game ends.
If you score +10 Combo you will gain a Rainbow Bubble which gives you a temporary pass for all bubbles.
Black bubbles will block the filter and you need to tap on it to clean.
You can check and compare your score on the leaderboard.
