There are eight cards for two or four players and nine for three, so everyone has equal turns. Player numbers in the corners identify ownership. Use different coloured pencils and write player numbers when playing on paper.
You can change your card before your first check. Clear selection clears only your draft. Hint gives search advice without losing points. Restart game repeats this setup; Rematch rotates the starting player.
Use Tab to reach cards and the grid. Within the grid, arrow keys move, Home/End move to the first/last square of a row, and Enter/Space selects an unclaimed square. Claimed squares remain readable.
