In this game you have to match pairs, In usual matching games the player is shown both the boxes he/she tries to match, but in order to make the game a little difficult, if you select to non-similar pair you will not be shown the second one. In this way you will only know that which picture is not in that box, but which picture is it, you will have to guess it yourself or you can explore it while making another match. You can put flags of different colors, to help you remember your guess about the box. At the end of game you will be told how much pairs you tried to finish the game. Have fun !
