It's a fun game until you get addicted and you score at certain level. The update first gave free low level unlimited boosters only to take that away after about 2 weeks or so. This only increases the frustration with the update that after you get to a certain level, the only way to win even for a short streak win is to get the very top boosters that are either hard to get or you have to pay for. The stickers are also an issue as you only get the same ones over and over
