  • Patent number: 4103895
    Abstract: A game or test of skill which is comprised of three principal components: a playing surface that either conceals or suggests a secret pattern of paths, a probe for selecting points on the playing surface, and an indicator that reveals whether a selected point belongs on the pattern of paths. In a preferred form of the game the playing surface is a small card on which is marked a grid that indicates the possible positions and orientations of the concealed paths in the pattern. A start point is indicated on the grid; the player places a hand-held pencil-like probe at the start point and tries to find a continuous path from the start point to the end point. The probe leaves no mark on the card, but the player is aided by the indicator which provides a signal when the probe is on-path--the signal ceases abruptly if the probe is moved off-path.
