Give your brain a workout and see how far you can go before getting a Brain Cramp.

A fun, educational game for kids and adults.

Tap all numbered bubbles in order from lowest to highest before time runs out.

The bubbles circulate on the water over the brain.

Each level adds an additional number to the brain pool as well as additional time.

There are 4 difficulties to play to challenges your number skills.
Higher difficulties introduce negative numbers to the mix with less time to solve.

Each incorrect tap will spawn a nano-bot at the bottom which will sink a number on contact. This could make the difference between a successful round, and a Brain Cramp.

Share your high scores for all difficulties on Facebook and Twitter.

Brain Cramp can have up to 10 players stored and will remember each players progress and high scores for each difficulty.

What’s New

Brain cramp

Tried this app recently and was immediately hooked! Easy to learn and very user friendly. I found myself holding out my phone at arms length to get a better view of all the numbers. I would definitely recommend this app to those who enjoy challenges!
