This is NOT a bubble game. The object of the game is to see how many tokens you can collect by watching 30 second videos. OR, It is a pyramid scheme masquerading as a game. It's fun to play if you have lots of money that you want to give to these greedy developers. The game is perfectly engineered to force you into paying money if you want to go past 200 levels. Description says "free," but only the first 100 or so levels can actually be reached, until they start trying to gouge you for money.
