Two agents under your control have entered a shootout at a junkyard. The circles indicate zones of safety. An agent on a circle can cover for a partner running along a path of the same color.
For example, in the first maze, one agent starts at B, and the other at L. The one at L is on a tan circle, and can cover as the other agent runs along the tan path, to C. After that, if the agent on the green C covers, the other agent can take the green path from L to G. With 21 such moves, it is possible to get one agent to N, and the other to Q. One might attempt to solve such a maze using two pens to indicate where the agents are located. Patience is also recommended.
A variety of randomly generated mazes of this type is provided. They are known under several names: logic mazes, multistate mazes, color mazes, or mazes with rules. They were originally developed by Robert Abbott.
