Get ready for a battle of wits in Invector, an abstract two-player game that takes the essence of the ancient Hawaiian Kōnane and adds a modern twist. The board is a rectangular grid, with dimensions ensuring an even number of spaces in one direction and an odd number in the other, and is initially filled with black and white stones in a checkerboard pattern. Your goal is simple yet challenging: capture all of your opponent's stones!

Players, one controlling black stones and the other white, take turns moving one of their stones per turn, starting with black. Passing is not allowed, but if you have no legal moves available, your turn is automatically skipped. And here's an interesting twist: the 'pie rule'. On their first turn, the white player has the option to switch colors, taking on the black stones and, consequently, the first move. It's a strategic decision that can change the course of the game before it even truly begins!

Movements are the key to the game. You can capture an orthogonally (horizontally or vertically) adjacent enemy stone in any direction. Additionally, you can move to an orthogonally adjacent empty space, provided that this move brings you closer to the center of the board, measured by Manhattan distance. Invector is a game that combines the simplicity of its rules with surprising tactical depth. Inspired by the simplicity and short-range captures of Kōnane, it offers a finite, decisive, and robust gameplay experience, where the complete destruction of the enemy army is the only way to victory. No frills, just pure strategy!
