An Artist's Mistake
This game develops attention, cognitive processes, and imagination. Silly pictures fit the sense of humor for the age group. The child needs to observe the image carefully and find the part which is not appropriate in the context. Selecting the wrong part in the image changes it to something that matches the scene.

This game is for the development of spatial cognition and logic. There are four tiles on the screen, each showing a piece from a different picture. The goals is to change the pieces of pictures until all the tiles show pieces of the same picture. There is an easy and a hard mode of this game.

This game is for the training of spatial thinking and perception. The picture is split into four tiles which can be rotated. The goal is to rotate the tiles in order to make a whole image.

This game trains attention and visual memory. There are cards on the table lying face down. Each round, the player can flip 2 cards. If the flipped cards have the same picture on the other side, they stay face up. Otherwise they get flipped back. The goal is to match all the cards. There is an easy and a hard mode of this game. The solution is shown briefly at the beginning of the game to help the child to memorize the pictures on some of the cards.

A child can play all of these games alone, yet the assistance of a adult may be encouraging at the start.
