BoneGames (http://www.bonegames.com) produces a number of do-it-yourself free games. You download a PDF containing rules and components, and print out what is required for play.Tiles is an abstract card game for two or three players. Players play tiles to try to close areas of their colour to score points. The larger the closed area, the more points scored. The player with the most points at the end of the game wins.There are 45 square tiles, each subdivided into four triangular areas which are either white, black or gray. Each player is assigned a colour. Tiles must be played so the edge colours match already-played tiles if one cannot play any tile, one must discard instead. You can score only on your own turn. - BoardGameGeek
