Kachit Knight is played on a 4×4 board with the following setup:

There are 5 unit types in the game:

• Orthogonal knight , move like chess rook
• Diagonal knight , move like chess bishop
• Unpromoted leader , move like chess king
• Orthogonal leader , move like king or rook
• Diagonal leader , move like king or bishop

All pieces capture by replacement, like in chess.

Players take turn to either:

• Drop one of their 3 off-board knights on an empty square in the castle by their throne, as either orthogonal or diagonal
• step with unpromoted leader . If reaches grass field, promote to orthogonal or diagonal
• Move knight or promoted leader, afterwards selecting orthogonal or diagonal orientation for next turn

There are two win conditions:

• regicide - Kill the enemy leader
• infiltration - Move your leader to enemy throne
