Odd One In is a visual memory game for Android. Objects are laid out on the board, and they keep their places from round to round. Each round, exactly one new object appears. Your job is to tap it. It sounds easy with five objects. With fourteen, it is not.
At first the board grows: the new object lands in an empty place. Once the board is full, the new object takes the place of an old one, so where it stands tells you nothing. Only your memory of the board can find it.
- A board that remembers you — objects stay put, old ones leave for good, look-alikes and shuffles come later. How the board works

- Six worlds — Food, Toys, Fruits, Animals, Ocean and Transport, 36 objects each. Six worlds
