Tribble Trap

Tribble Trap is a puzzle game where the player hunts a tribble, a furry little creature from the Star Trek universe. The game is played on a 7x7 grid where each square represents a galactic sector in deep space. The tribble, which is hidden, moves between the sectors and the player's task is to trap it without killing it. The only info given about it is its position the previous turn. For each turn the player can shoot out one of the sectors by entering its coordinates. That then prevents the tribble from moving to it. The game is won when all the sectors surrounding the tribble are destroyed since it then can't make any further moves. It is game over if the tribble is shot or if all available shots are used up.
