Sobre este jogo
Choose Your Numbers Carefully

-Collecting as many numbers as possible will maximize your score. Analyze all numbers on the screen to determine the most efficient order to grab as many numbers as possible.
Fast forward to speed up the game or move unwanted numbers out of the way.

-Fast forwarding the game can help speed up the flow of early rounds in repeated runs or speed up your down time between rounds, if you are daring enough..
Use BOMBS to clear all numbers on screen to save yourself from certain death.

-If you are in danger of being hit by a number you dont need and there is nowhere save to move, you can destroy all numbers on the screen by using a bomb. Keep in mind you only have 3 of these. Conserve your ammo...
Think quickly, collect an incorrect number and it is instant game over.

-Remember you have to stay between 0 and 9. You can see your current value by looking at the addition signs filling up the squares on your character cube.

Mighty Math is a mind bending fusion of arcade survival and brain training all in one. Anyone can pick it up and play. It starts with a simple premise, collect a required set of numbers before all numbers run out to survive each round. As you collect numbers you will change the player value. You must maintain a player value between 0 and 9. If you go over or under this value range you will be instantly destroyed.
Although the game starts off with a simple concept, it contains endless rounds and ramps up in difficulty immensely. Survive as long as you can to set high scores to share with your friends!
Enjoy wild randomized runs with varying sets of numbers and traps for a unique experience each run!
Train your brain as you survive the mathematical onslaught in Mighty Math!
