I like the idea of having a bingo game to play from time to time and downloaded this to earn credits in another game. If you're thinking the same I wouldn't suggest it. To level up past level 35 you need to use power up's and 80+ tickets. I saved up for a few weeks and still didn't have enough power up's to achieve the daily tasks and only levelled up from 42-50 after saving 1600 tickets and almost 200 powerups. You can't really progress faster without paying a lot.
