The Grimace Monster is ready to help you strengthen your memory and offers the Grimace Memory Challenge game for this. It contains cards with images of Grimace. There are quite a lot of them. But you will start with only four cards. Open them and find two identical ones and admire their lightning-fast destruction. Further, the number of cards will gradually increase, and therefore the tasks will become more difficult. This way you will gradually improve your visual memory without even noticing that you are training it in the Grimace Memory Challenge.
