Houston, We Have A Primate Problem Baby Monkey Astronaut will drive you bananas, but itâ's the easiest game youâ??ll ever learn to play & a hugely effective way of improving memory skills. Turn over the cards in sequence as you countdown from 10 to 1 without skipping a number. Itâ's more difficult than you think though, as you donâ??t know where the next number might be. Itâ's a monkey memory mix-up!
