Keep a string of numbers in mind, then work out the sum. This brain game trains memory and arithmetic at the same time as the levels grow more complex.
About the game
Kobadoo Arithmetic combines two skills that rarely get trained together: remembering numbers and calculating with them. You memorize a sequence, then add it up, which keeps both your recall and your mental math on their toes.
Its design is simple and uncluttered, yet each new level asks a little more of you. It is a good companion for students brushing up on sums and for adults who want a stimulating daily exercise for the mind.
