This game is so addicting that you won't notice the time pass. The rules are simple - coloured droplets spill out of the pipe and fall down, into the puddles. Your task is to rotate the phone, so the droplet falls directly into the puddle of the same colour. The game is simple and intuitive so everyone can play it, regardless of age. Even a two year old (and this is verified)! Lite version has limited number of levels to 7.
