The game is played on an empty 10x10 triangular hexboard. Each player drop a stone into an empty cell.
Black has a winning position. White cannot stop Black from winning in 4 turns.
There is a ZRF to play Y with Zillions.Check also Hex and Poly-Y.
A variant is Caeth Y where players
take a little longer to control each cell: [from
1- * 2- / \ 3- *-.-* 4- / \ / \ 5- *-.-*-.-* 6- / \ / \ / \ 7- *-.-*-.-*-.-* 8- / \ / \ / \ / \ 9- *-.-*-.-*-.-*-.-* 10- / \ / \ / \ / \ / \ 11- *-.-*-.-*-.-*-.-*-.-* 12- / \ / \ / \ / \ / \ / \ 13- *-.-*-.-*-.-*-.-*-.-*-.-* 14- / \ / \ / \ / \ / \ / \ / \ 15- *-.-*-.-*-.-*-.-*-.-*-.-*-.-* 16- / \ / \ / \ / \ / \ / \ / \ / \ 17- *-.-*-.-*-.-*-.-*-.-*-.-*-.-*-.-* \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ A B C D E F G H I J K L M N O P QPlayers alternate turns, capturing an edge between two vertices on each of their turns. When a player controls half or more of the edges leading into a vertex, they gain control of that vertex. (Specifically in Caeth Y: control of one edge into a corner vertex, two edges into a side vertex, or three edges into a centre vertex are enough for control.) As in Y, the goal is to make a connected chain of vertices that touches all three sides of the board; the three corners count as members of both sides to which they are adjacent. Note that the connected chain is a chain of vertices, not of edges. The second player may utilize the swap rule if they so desire.
Y is very suitable to use with progressive mutators. The 122*, the 123* and the slow 122344566788... sequences produce very nice games, if we add a restriction: every dropped stone from the same sequence must belong to different groups.
