Maze Trap

From the envelope:

Maze Trap is a 3-DIMENSIONAL strategy game you color, build, then play. Move your "runner" through the maze as quickly as you can while, at the same time, trying to obstruct your opponent's runner with your "blockers." Pieces move around maze walls, over bridges and through warp zones. The first runner to get to the finish, wins.

Maze Trap is a abstract racing game played in a maze. Each player has one runner, four blockers, and one super blocker; regular and super blockers are identical except that regular blockers move up to six spaces and super blockers move up to twelve spaces.

In a round each player moves exactly three of their five blockers, after which each player moves their runner. Runners move up to ten spaces, including zero, but if a runner is blocked so that it can't possibly move ten spaces it returns to start. There are two sets of "warp zones" which teleport pieces between them.

The three-dimensional aspect of the game (aside from the pieces) are bridges across the center of the board, but they could have been represented in two dimensions.
