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.

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.
