Introduction Mosaic is a territory game played on an initially empty hex board. Two players, Red and Blue, share a set of tiles, red on one side and blue on the other. Place or flip tiles, but not both Players take turns placing or flipping tiles starting with Red. You either place one tile with your color showing or you flip one or more enemy tiles to your color. You never both add and flip tiles in one turn. If you have a placement or flip available you must do one of them. Otherwise you must pass until you do have a move. Tile placement You can place a tile adjacent to an enemy tile or adjacent to nothing. You must never place a tile adjacent only to your own tiles. You must never place a tile that reduces your number of groups. Tile flipping Flipping a tile must accomplish two things. It must decrease your number of groups and decrease the total number of groups - yours plus your opponent’s. Flipping is not mandatory, unless part of a multiple flip sequence (see below). Multiple flip sequence When you flip a tile, and while it’s still your turn, you may be required to flip additional tiles. If it’s possible to flip any tiles subject to the preceding section, "Tile flipping", which are adjacent to a tile flipped earlier in the same turn then you must flip one of them. If it’s still possible to flip more tiles adjacent to tiles flipped earlier in the same turn, you must flip another one, and so on. Your turn concludes when no more tiles adjacent to currently flipped tiles can be flipped. Tiles can be flipped in any order in a multi flip sequence. Which tiles get flipped in a multi flip sequence is not necessarily predetermined. Sometimes a player has a choice. Object of the game The game concludes when there are no more legal moves available. NOTE: Tiles can still be flipped after the board has filled up. The object is to have the most tiles on the board when the game ends.
