About this 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? From Level 1 to the 64-bit integer limit — 9,223,372,036,854,775,807 levels — your journey is effectively infinite.
