Unane

Ūnane (ooh-NAH-nay) is played on a Kōnane board. That is, a rectangular grid of pits that can hold one stone each. The grid can be any size, with at least one even dimension. The board is initially filled with a checkerboard pattern of black and white stones. Mark Steere designed Ūnane in April 2026. PLAY The two players, Black and White, take turns either moving a stone of their own color, or removing a stone of their own color (but not both actions), one stone per turn, starting with Black. Passing is not allowed. Ūnane uses the pie rule. White, on his first turn, has the option of switching colors and becoming Black, claiming the first move as his own, instead of moving a white stone. CAPTURING MOVES You can move to capture an orthogonally (horizontally or vertically) adjacent enemy stone in any direction. REMOVALS You can remove a friendly stone which has no orthogonal adjacencies with enemy stones. OBJECT OF THE GAME The goal is to have only one orthogonally interconnected group of your color (which could be a single stone). You can win on your turn or on your opponent's turn. If, after your turn, there is only one friendly group and only one enemy group, you win.
