Gloop is a domino-like strategy game for 2-8 players, using special Gloop tiles. The Gloop tiles are a set of 91 square tiles that show every unique way that paths can be drawn between pairs of points on each tile side. Players start by randomly drawing six tiles into their hand, and placing a pair of matching tiles in the centre. Players then take turns either: 1) forming tiles from their hand into matching 2x2 patterns, 2) matching one of their 2x2 patterns with the central pattern, or 3) drawing a random tile into their hand. The game is won by the player who has no remaining tiles. The Gloop tiles also allow a number of interesting puzzles, such as finding the greatest number of tiles that pack to form a single closed path, packing all 91 tiles into a 7x13 rectangle with the smallest or greatest number of paths, etc.
