How to solve a Queens puzzle
Place one queen in every row, every column, and every colored region, with no two queens touching — not even diagonally. Tap a cell once to mark an X where a queen cannot go, tap again to place a queen, and tap a third time to clear it. Swipe to mark several cells at once, and placing a queen auto-marks the cells it rules out. New to the game? Read the full how to play guide.
