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.
Because unlimited mode hands you a new board every time, it's a good place to test techniques from our strategy guide — like spotting a region trapped inside a single row — before relying on them in the daily puzzle. If you'd rather practice on a fixed board you can revisit, the numbered puzzle library keeps the same layout every time you open it.
