Today we want to introduce you to a rather interesting puzzle game Odd One Out. In it you can check your reaction speed and mindfulness. Its essence is quite simple. Before you on the screen you will see the playing field divided into squares. All squares have the same color. But one of them has a darker color and differs from the others. Your task is to quickly find it and click on it. For these actions you will receive points and go to the next level. With each new level the speed of appearance of squares will increase, and the time allotted for their search will decrease. So make a decision faster.
