Four images displayed and the child trying to find the one that does not match.
Three of them belong to the same group (animals, clothes, fruits...) and one of them do not belongs to the group.
If the child chooses the correct one, a reward message sounds, another four images are displayed and so on.
If the child choose a wrong picture, an error message sounds, the child trying again and the number of wrongs answers are increased.
Have fun!!!
