This is a game that will train your brain, improve your concentration and reaction time, and also test your visual acuity. You will have to find the differences between two almost identical images, which will appear on the screen. You will be challenged with the task of finding as many differences as possible. You will be given a couple of hints in case you get stuck.

The game is divided into several levels of difficulty, so you can start with the easy ones and work your way up. You can use the "hint" option to help you if you get stuck.
