I liked the game until I found that it cheats. The boosters don't always do what they are supposed to do, or when the blocks fall you clearly see 6 or 7 in a row but when it falls it turns into . The upper levels are like casino games, nothing to do with skill. You do need boosters and coins to advance. The rewards are bad and booster packages get expensive.I spend lots of money. Don't pay attention to their response to contact the developers. I DID, unless you RECORD your play they do nothing.
