oxxdoku vs Queens Puzzle !

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 10 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. Privacy Policy: https://huashan.studio/oxxdoku/privacy
