Reviews: What People Think About iAddThree

Rating: 5/5

Was looking for an app that would keep my brain thinking. This math one sure does. The adding is pretty easy except in round 28 and up when it speeds up. The subtraction is a little more challenging but it’s the challenge section that keeps u on your toes. But you got to get through the add and subtract section to get to the challenge section. A little workout for my brain.

About iAddThree

Train your brain and improve your focus with the simple yet challenging math game, iAddThree.

Adapted from an exercise that was used to measure cognitive focus in the popular book Thinking Fast and Slow by Daniel Kahneman, iAddThree engages your mind by bending the rules of basic math to give your brain the mental exercise it deserves.

THE RULES-------------

It's simple. Just add 3 to each of the four numbers that are presented. The challenge? No double digits. Instead, you must wrap around to 0.

Normally, 8+3=11, but in iAddThree, 8+3=1. Think of it as a line of numbers that are constantly repeating.

8 -> 9 -> 0 -> 1 -> 2 -> 3.

The struggle provided by this simple math game will have you boasting about your high score to all your friends.

So, how well do you think you can iAddThree?
