The Game of Y


Y was invented by Charles Titus and Craige Schensted. It is another game that deserves to be more widely known and one that will surely appeal to the abstract game enthusiast. Here is an introduction to the game.

April 2018. Y will soon be one of the the games available online on my game server, Gorrion. [ http://www.dashstofsk.net/gorrion.php ]. It will be in both variations: straight and curved boards. Please do join in the fun. I am 'dashstofsk' at the server and will welcome challenges.

The Game

The game is a connection game played between two people across a triangular board. Both players take turns to place a piece on the board. Black goes first. The objective is to be the first to complete a chain of pieces that connects all three edges of the board. Corners are common to both of the adjoining sides. A game cannot end in a draw.

The Swap Rule

The second player ( white ) has the option to 'swap' immediately after the first player has made his first move. If swapped the roles will be reversed. The first player will take the white pieces and will play against his own first move. The second player is given a swap option in order to counter the first play advantage that the first player would otherwise have.

The Game Board

The game can be played on a range of board sizes. Size 19 ( 19 nodes along each edge ) should be the minimum for serious play. With anything smaller there will not be opportunity for enough rounds of attack and counter-attack.

Note that boards with sizes 19, 22, 25... ( incrementing in jumps of three ) will have a node in the direct centre of the board. With other sizes the board centre will fall on the mid point between three touching nodes.

One interesting variation is to play on a board that has pentagons along the corner axes. There is good logic for this configuration. The reduced number of nodes along an edge will make it easier for a player to defend a side against a centre attack.
