Snark Hunt is a game of logical deduction. You are given the simple rules of behavior of vorpal beams as you shoot them into a grid. By their behavior you must determine the whereabouts of the hidden sparks. Don't be fooled by this seeming child's game. Techniques similar to this were used in deducing the structure of DNA. This game, though a bit noisy, is absorbing and fun to play. Reading the BASIC code offers information on the use of sound, the joysticks, color, alternate character sets and BASIC graphics.
