One rule. Every cell.

How it plays
One rule, and it never changes.
Boards grow bigger and threads grow longer. The rule stays the same, so the puzzles get deeper, never more complicated.
Fill every cell
A board is done only when no cell is left empty. The short way often starves the others.
Never cross
Threads never cross or share a cell. Every board is proven to have exactly one answer.
What's inside
Plenty to play.
A campaign to work through, a board a day, and modes for five minutes or fifty.
Levels
Twenty worlds, each ending on a boss board played on hearts.
A board a day
The same board for everyone, every day. Keep your streak going.
Rush
Clear boards against the clock, build a combo, beat your best.
Endless
Boards that never run out, matched to how you play.
Hints that explain
A Nudge shows the next sure move and says why. You draw it, and keep your stars.
Rooms in the Den
Decorate Knotty's home room by room, and collect hats, scenes and palettes.
Take a look
Made to feel good.
Every thread you draw plays a note, joins light up, and the finish lands with a flourish.
