Recall

Recall is one of the games that can be found in The Cube. It requires a photographic memory to succeed; one must find the square that appears the first time but does not reappear.

Instructions
''"A number of red squares will appear on the floor of The Cube. After five seconds, they will disappear. They will then reappear, but one will be missing. You must place the marker on on the location of the missing square." ''
