Myriath (2009)

Myriath is an abstract strategic tile placing boardgame for 2 to 4 players. Aim of the game is to get as many concave (inward-curving) ends of your tiles connected to other pieces as possible. When placing a tile, at least one of its concave ends must connect to a convex (outward-curving) part of a tile that belongs to an opponent. Any other concave ends may connect to any tiles, be it opponent tiles or the player's own tiles. The player with the lowest number of unconnected concave ends (also counting the concave ends of tiles not placed) wins the game.
