## Description

"Calm the mind, spark the brain. Just 10 minutes a day, give your mind a workout. Let oxxdoku keep you company on a cozy afternoon."

If you enjoy the reasoning of Sudoku and the process of elimination in Minesweeper, oxxdoku sits right between them.

One O in every row, every column, and every color region. Mark the rest with X. Two O's can never touch — not even at a corner. Double-tap a square to place one.

Every board is solvable by pure deduction. No level will ever ask you to guess: boards that cannot be reached step by step are discarded before they ever reach you.

• 100 campaign levels, on boards up to 10×10
• A fresh daily challenge and a daily check-in, both from level 20
• Undo, hints, three lives, gentle haptics
• Plays offline, anywhere
• About 38 MB — kind to an older phone

About the ads: no account, no start-up popup, no consent form to dismiss. Watching one for an undo or a hint is always your choice. From level 20 a full-screen ad can appear after you clear a level; close it right away if you like — the next board is already waiting.

One row · one column · one color · one O.
