A fun educative game that will train your arithmetic and memory. You start with a number which step by step you need to calculate a new number. For example: you start with 5 and next you'll have to add 11 the next number is 16 next you'll might have to divide by 4 the new number will be 4 and so on... until you answer wrong or you run out of time. From time to time you need to remember a step like "remember +5" , you need to remember +5 because this step might return later on. Or if you need to inverse a step you'll have to subtract 5. "Inverse" in this game means you'll have to change adding to subtract, multiplication to division and the other way around. Good luck, have fun.
