Make math as big and fast as possible! In Calcutron you are given a board of digits to use to make simple math equations. Add, subtract, multiply and divide numbers as big as you can to score more and more points. Train your brain to see and do math as quickly and easily as possible.

In timed mode you are given 90 seconds to score as many points as you can with new numbers being added after every submission. In clear mode you are given 45 seconds to clear out as much of the board as possible, with all points doubled if you can completely clear the board.
