4 mugwumps are hiding on a 10x10 grid. Players pick a cell and are told how far away each mugwump is, rounded to the nearest 10th (one decimal). The game can be played completely in one's head, and played very well if the player is able to calculate The Distance Formula in their head. The game can be played precisely, and won in only 4 moves, if the player can calculate or visualize the geometry in their head and gets lucky by getting one of mugwumps on their first guess. The 101 BASIC Computer Games book, however, suggests the player draws out a precise grid and use a compass to triangulate the location of the mugwumps.
