Fendoku

A cozy logic puzzle with 999 campaign levels, a shared daily challenge, and pressure-free zen mode. Hundreds of adorable themes. No ads, no accounts.

Fendoku is a cozy logic puzzle: place one marker in every row, column, and colored region — and no two markers can touch, not even diagonally. Easy to learn, endlessly satisfying to master.

THREE WAYS TO PLAY • Campaign — 999 hand-tuned levels along a winding, illustrated map trail. Boards grow from friendly 5×5 grids to brain-bending 12×12 giants, with themed sections that unlock new looks as you climb. Earn up to three stars per level. • Daily Challenge — one shared puzzle per day, the same board for everyone worldwide. Build a streak, replay past days from the calendar, and beat your best times. • Zen — pick any size from 5×5 to 12×12. No hearts, no timers, no pressure. The next puzzle is always ready the instant you finish.

MAKE IT YOURS • Hundreds of built-in themes swap the board colors, mascot, markers, and celebration puns — cats, dogs, food, space, ocean, sports, travel, and more. • Unlock new themes by completing campaign sections. • Design your own themes in the built-in editor with a live board preview.

THOUGHTFUL BY DESIGN • Tap to mark, double-tap to place, drag to paint marks across cells. • Free hints and marking boosters every day when you get stuck. • Win celebrations with confetti, stars, and best-time stats. • iCloud sync keeps progress in step across iPhone, iPad, and Mac. • Supports Reduce Motion; plays fully offline. • No ads, no account, no tracking. Your data stays yours.

Whether you have two minutes or a whole evening, Fendoku is a warm little corner of logic to settle into. Come solve, purr, repeat.
