Queens Star Battle, also called simply Star Battle or Two Not Touch and popularized by the LinkedIn Queens game, is a logic puzzle played on a square grid divided into colored regions. Your goal: place one crown (one star) in every row, every column, and every color region, with one hard restriction: no two crowns may ever touch, not even diagonally. Every puzzle here has exactly one solution and can be finished with pure deduction. No guessing, ever.
It plays by the same rules as the LinkedIn Queens game: one crown per row, column, and color region, with no two crowns touching. The difference is unlimited puzzles here, five grid sizes from 7×7 up to 10×10 and 11×11, a fresh daily board, and hints that teach real logic-solving techniques instead of just revealing squares.
