It is a sort of "pairs" game to be played during a maze chase! Whilst keeping an eye at the ghost chasing you, try to pick and throw cards one near the other. They will turn for a few seconds. If the are equal, they will dissolve. If not, try to memorize letter and position and try again with another card. Levels of increasing difficulty. Very funny game by Inufuto, for the 16K VIC-20.
