Very creative idea. It was hard to reach the higher numbers on the bingo card so it seemed the incentive was to just play the first row of low numbers. I liked the end game animation.
It can be a bit tricky to get up there. Our advice would be to use the time at the beginning to mash all the way up and work your way down. Thanks for the compliment on the scoring animation though! We spent a lot of time on it :3
