Number Munchers is an educational math game published by MECC in 1986 for the Apple II, and later for DOS and Macintosh. You steer a green Muncher around a grid eating only the numbers that fit the rule at the top of the screen — multiples of seven, primes, equal to twelve — while dodging the Troggles that patrol it. It stayed in school computer labs well into the 1990s.
