Description

Multimatch I and II deals with square tiles, while Multimatch III and IV concerns triangular tiles.
The box of Multimatch III contains a plastic hexagonal trail, and an acrylic set of MacMahon's Four-Color triangles. All 24 triangles are divided into three equal triangles (with short edges joining the centre to the corners) coloured with 4 colors.
The 1991 edition Kadon rulebook contains a large section of puzzles, and rules for 3 games, plus variants.

The games are:
Multimatch. Players take turns placing tiles on the hexagonal trail. The first piece placed on a border of the board determines the color of that border. Last player wins.
Outmatched. Players divide the tiles equally (face-down) and then race to assemble their group into a symmetrical shape, with tile edges matching.
Closure. The tiles are assembled into a random (but edge-matching) group. Players take turns "closing" one of the 3 colors by moving as few tiles as possible. Closing a color requires leaving no exposed edges of that color. Moves may not separate any tiles from the group.
