Brain Crunch Subtraction Match

Ready for a challenge?

Simple concept to learn, difficult to master:
Subtract 1 number block from another to equal the number cascading down the screen.

Get 3 matches before it hits the bottom to launch a solar flare! Clear all number blocks before time runs out to complete the level. Reach new high scores with time bonuses and by choosing adjacent blocks.

Great for students, or anyone who wants to improve brain power and reflexes!

50 levels, from easy to ridiculous!
