One marker. Every row, column, and region.
Fendoku is a colorful Regional Queens puzzle: place one marker in every row, column, and colored region, with no two markers touching — not even diagonally. Play a 999-level campaign, a daily puzzle everyone shares, or an untimed Zen mode, all wrapped in hundreds of unlockable themes.

Campaign
999 progressively harder levels on a winding map trail, ramping from 5×5 grids to 12×12 across eight difficulty bands. Deterministic breather levels give you a breather every so often, and finishing one of the trail's ~112 themed sections unlocks new themes. Earn up to three stars per level.
Daily Challenge
One shared puzzle a day, rolling over at 08:00 UTC for everyone. Grid size follows the weekday, so the whole world is solving the same board. Build a streak and replay any past day from the calendar.
Zen
Pick any size from 5×5 to 12×12. No hearts, no pressure — just chain puzzles back-to-back whenever you feel like it.
410 themes
Every theme swaps the board's palette, markers, and mascot. Unlock them through campaign play, or design your own in the built-in theme editor.
