In a standard bingo card (a 5x5 grid with numbers from 1 to 75), you can have about 552 septillion different arrangements for the numbers, making it almost impossible to ever get the same card twice. Yet, your chances of winning are much higher, and only depend on how many people are playing.
Bingo Blitz takes normal bingo, and gives it a twist by adding power-ups, items to improve your performance, achievements, and a dancing cow (ok, maybe not the last one). And you get 50 credits, worth $4.99, to go crazy on those bingo games. Of course, this is all for FREE!
