Where to swap (y)

• The red marked hexes should be swapped.
• The blue marked hexes should not be swapped.

Regular Y

Size 10

The hexes marked (*) are proven to be winning or losing. The rest are highly likely but not proven.

Size 11

For sizes 11 and larger, the swap map maps are not proven, but a cell is only shaded red or blue if it is likely to be accurate.

Size 17

Uncertain cells are shaded gray. These cells are marked (+) if they are more likely to be strong cells (that Blue should swap) and (-) if they are more likely to be weak cells (that Blue should not swap).

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

Bent-27

Again, status unknown but presumably within reach for computers.
