Description
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.
