Cross Out: Logic Puzzle Game

Welcome to Cross Out: Logic Puzzle Game — One Mark, One Solution, Infinite Deduction. No guessing, no luck — just pure logic. Cross Out is a deduction puzzle built on one elegant rule: place exactly one X in every row, every column, and every colored region — and never let two X's touch. Every board hides a single valid solution, and it's yours to uncover one careful mark at a time. Your mission: read the colored regions, rule out the impossible, and place your X's until every row, column, and region holds exactly one — with none of them touching, not even at the corners. Tap to leave a note, tap again to commit your X, and let the grid guide you to the only answer. Can you find the one solution hiding in over 9 quintillion puzzles? 🧩 Key Features ❌ The Satisfaction of the Perfect Deduction Feel the click of the final X dropping into place and the whole grid locking into solved. No trial-and-error needed — every move follows from logic, and every solved board is earned. 🧠 9 Quintillion Unique Challenges The journey literally never ends. From breezy 5×5 grids to dense 10×10 boards packed with colored regions and blocks, the engine generates unique, guaranteed single-solution puzzles that scale with your skill. You'll never solve the same board twice. 🌈 Clean, Focused Design A calm, distraction-free grid built for deep thinking. Crisp colored regions, clean black X's, no clutter — a modern aesthetic designed for clarity and focus. 🔲 Master Every Constraint As you climb, the grids fight back. Blocked cells rule out squares entirely, locked clue X's anchor your opening, and the no-touch rule keeps you honest. Every region and every neighbor changes where your next X can go. 💡 Smart Solver Hints Lost the thread? The built-in hint doesn't just reveal a square — it points to the next move logic demands, flagging a wrong X to remove or the very cell that's forced. 🤝 Effortless Marking Drop an X where one already sits in that row, column, or region and the old one simply moves to your new cell. Think out loud on the board — no manual cleanup, ever. 🌎 Reach the Unreachable How far can your logic carry you?
