How to solve a Starstruck puzzle
Place one star in every row, every column, and every colored region, with no two stars touching — not even diagonally. Tap a cell once to mark a cross where a star cannot go, tap again to place a star, and tap a third time to clear it. Swipe to mark several cells at once. Solve the whole board and every line will hold exactly one star. New to the game? Read the full how to play guide.
