Where to swap (y)

• the red marked hexes should not be swapped
• the blue marked hexes should be swapped
• the star marked hexes are defining the Y board.

Regular Y / Bent-27

This board (on which the pieces are placed on the intersections) should be within reach for computers, but no results are known so far.

Master Y

In Master Y, the first player places one piece on the board, and each subsequent move consists of placing two pieces on the board.

• the red marked hexes are losing first moves
• the blue marked hexes are winning first moves

Master Y / Bent-27

Again, status unknown but presumably within reach for computers.
