Simon Says Games is a classical memory game. A command starting with "Simon says" means the players must obey that command. The game progresses in three difficulty levels, i.e., items from an enlarging memory sequence are formed from four cards, nine cards, and sixteen cards. Between levels, a short tapping game is included to make children more engaged and motivated. With a progressively increasing level of difficulty, this game is a perfect memory practice for all pre-school children of various expertise.
