So far so good

The problems drop from the top to the bottom. If you get one wrong it drops to the bottom. After getting so many in a role correct, a bomb will come down and destroy the one you got wrong. I would recommend this game for anyone who wants to become faster in answering the problems. I just started so I'm not sure if you unlock all the numbers by getting to higher levels or if you have to pay to unlock them. I would recommend this game.

Super fun app!

Kids will love this app! It builds their fact fluency in a fun way and gives them a sense or urgency (automaticity) so their #s don't drop down. The bombs will rescue them from any past mistakes after a few consecutive right answers! Thank you for sharing!
