A casual game, guess your photos. Two ways to play:

1) Play yourself: The game will randomly pick one of your photos and cover it. But you can draw with your fingers to reveal a part of the photo. Guess which photo is it, guess who is in it.

2) Play with others: You can choose one of your photos, for example, if someone is in this photo, you can draw to reveal only his eyes, and all other parts are covered. Then, you can let others guess who this is.

The game is very small, needs only a bit storage space, and it is permanently free, can be kept in the phone, play it when you are boring.
