How to play Number Kingdoms
Fill every empty cell with a number from 1 to 8. The board is divided into six outlined regions called kingdoms, and each kingdom must contain every number from 1 to 8 exactly once. The dark cells are stones.
The remaining rules come from chess. Two cells that hold the same number cannot share a row, column, or diagonal unless a stone lies between them; the stone blocks that line. Two cells that hold the same number also cannot be a knight's move apart, meaning two cells in one direction and then one cell to the side. A stone does not block a knight's move.
