Very fun game, problem is bingo tokens are outrageous to buy. And some levels are very hard to pass, unless you use the higher levels to get the shadow cards you need, but the higher levels cost alot of bingo tokens. I can win all the lower cards playing lower level using less tokens but can never win higher levels I need because tokens are to expensive. I'd raise the stars when tokens are more affordable and shadow cards are fairly distributed throught levels of bingo.
