These are the rules for invector

New page

Invector 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 one even dimension and one odd dimension.
The board is initially filled with a checkerboard pattern of black and white stones.
Figure 1 shows a 5 x 4 grid. Mark Steere designed Invector in April 2026.
PLAY
The two players, Black and White, take turns moving stones of their own color, one
stone per turn, starting with Black. Passing is not allowed, but if you don't have a legal
move available, your turn is skipped. Invector 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. In Figure 2, Black can capture by replacement a white stone
marked with a green dot, but not the white stone marked with a red dot.
NON-CAPTURING MOVES
You can move to an orthogonally adjacent, unoccupied pit, closer to center, Manhattan
distance. That is, your stone must be closer, via a series of orthogonally adjacent pits, to
a center pit after your move than it was to a center pit before your move. [There are two
center pits.] In Figure 3, Black can move to any of the orthogonally adjacent pits
(intersections) marked with a green dot. But Black cannot move to any of the
orthogonally adjacent pits marked with a red dot.
OBJECT OF THE GAME
The goal is to capture all enemy stones. When you have removed all enemy stones from
the board, you win.
DESIGN NOTES
Invector was inspired by the ancient, Hawiian game of Kōnane. True to the spirit of
Kōnane, Invector begins with a checkerboard pattern of stones, has short range captures,
and is extremely simple. Invector simply combines two basic, off-the-shelf ingredients:
orthogonal, adjacent capturing moves, and orthogonal, adjacent moves closer to center.
Nothing fancy, but it works. Gameplay is finite, decisive, and robust. Flour and water
wins the day.
Invector is ultimately its own game. Kōnane is more violent. Every move involves at
least one capture. But Invector is more lethal. Armies don't just come to a standstill,
shake hands, and part amicably. One of the armies must be destroyed to the last man.
