Trichet is a tile placement game of territory closure for two players. Rules Tiles: Two players, White and Blue, share a common pool of 96 triangular Trichet tiles. Each side of each tile is split into two coloured regions by a circular arc centred on one corner. Start: White starts by placing two tiles in the centre of the playing area. Play: Players then take turns adding a tile of their choice to touch at least one edge or corner of an existing tile, such that all neighboring regions match in colour. Auto Moves: Each move may result in one or more positions at which only one tile in one rotation may be placed such that colours match; all such positions are automatically made as part of the the move. Each auto move may result in additional auto moves, hence each player move will usually result in multiple tile placements. Aim: A player wins by completing a region of their colour more complex than a circle. For example, Blue wins the game shown in Figure 3 with a closed region that visits 14 tiles. http://www.cameronius.com/games/trichet/
