Syon (1987)

The object of this abstract strategy game is to bring together 4 sun pieces (2 each of 2 different colors) into a connected chain. Each player has a hidden goal card with his 2 colors. This means that many times two players have a color in common, making it a challenge to help yourself without helping your opponent even more. The game is played on a 6x6 grid of points. 24 planets are placed at random on these points at the beginning of the game. 8 sun pieces are placed in the square spaces formed by the grid points. On your turn, you can move any one planet to any empty point on the grid, or, if a sun is surrounded by 4 planets, you can move that sun to an adjacent space. The only restrictions are that you cannot undo the last player's move or move a planet away from a completely surrounded sun. You win immediately if your 4 suns are connected in a chain of any shape.
