How do you get from 3 to 13 in two operations? How about from 7 to 83 in three operations? These questions form the base of OpTap, a mentally challenging game that requires quick thinking and problem solving skills. Each tap performs the same operation (a combination of addition, subtraction, and multiplication) on a randomly selected starting number, but you don’t get to see the operations or the intermediate numbers, just the first and last. The goal is to figure out what operation(s) were applied to the first number to get to the last. The rules may be simple, but finding the solution isn’t quite as easy!

Three difficulty levels: 1 Op (only one operation is applied before the result is displayed), 2 Ops (two operations are applied before the result is shown), and 3 Ops (three operations are applied – this one is a bit difficult!). Start with 1 Op and then work you way up to more difficult levels!

Enjoy two different modes of play: Practice (all the time you need) and Game On (race to beat the clock in order to advance to the next level). Gain enough points and you’ll make it on the High Scores page!
