Mind Maze

In Mind Maze, each player builds a maze for the other to navigate, sight unseen. They then race each other.

The board stands vertically between the players and serves as a screen. On your half, you build a maze by placing a number of baffles between posts. Handicapping can be achieved by reducing a player's number of baffles. When the race starts, you use a magnetic controller to nudge your steel ball (on the opponent side) through the maze, toward the exit hole. When you hit a baffle, your ball fails to follow the controller and drops to the bottom, where you must grab it anew.
