Number Munchers is a 1986 video game and a spin-off to the title Word Munchers. It was made by MECC for Apple II, then ported to DOS and Macintosh in 1990. The concept of the game was designed by R. Philip Bouchard, who also designed The Oregon Trail. Two versions of the game were released being the Consumer Version (for home use) and the School Version (for classrooms). After The Learning Company acquired MECC, the game was rebranded as "Math Munchers". Gameplay The player controls the muncher who must move around a grid and munch on numbers that match the logic rule above, while avoiding the threatening troggles. As the player progresses the levels, the logic rules have bigger numbers and harder difficulty and multiple troggles pursue the muncher. Modes of play There are five different modes of play in Number Munchers to advance players' mathematical skills. These modes include Multiples, Factors, Primes, Equalities, and Inequalities: Multiples - the objective is to find multiples of the number given. If presented a 3, one would select numbers like 3, 6, 9, 12, etc. Factors - the objective is to find factors divisible by the number given. If the number is 12, one would choose to eat 1, 2, 3, 4, 6, and 12. Primes - this mode helps players find prime numbers that are only divisible by 1 and themselves. e.g., 2, 3, 5, 7, 11, 13. Equality - this mode gives players the chance to find equations equaling the current number. If given the number 6, one would 'munch' 3 x 2, 3 + 3, 12 / 2, and so on. Inequality - this mode gives players the number and they must select the equations that DO NOT equal the current number. If given 6, one would eat equations such as 4 X 2, 18 / 9, and 3 + 5. Troggles The Troggles are monsters with two legs and a large head, whose goal is to eat Muncher and/or disrupt his progress by rearranging things on the board. Levels 1, 2, and 3, contain only one Troggle on the grid at any given time. A second Troggle appears starting with level 4, and a third appears starting with level 8. After approximately level 18, the game (especially the movement of the Troggles) accelerates to make responsible munching more difficult. There are several type of "Troggles". Each type of Troggle
