Draw one line. Hit every number. Fill every cell.
Knotty is a calm, clever path puzzle. Start at 1, drag through the numbers in
order, and cover the whole board without crossing your own line. Easy to
learn, satisfying to master.
A FRESH PUZZLE EVERY DAY
Everyone gets the same daily knot. Solve it to keep your streak going, and
earn streak freezes to protect it on busy days.
TWELVE WORLDS OF TWISTS
Work through a campaign that grows from gentle 5×5 boards to tricky 8×8
grids. Each world adds something new: portals that jump your line, one-way
arrows, slippery ice, keys and gates, crumbling tiles, switches and fog.
RACE THE CLOCK IN ENDLESS
Puzzles keep coming and get harder. Every solve buys more time, and clean
solves build a score combo. How far can you go?
BEAT THE RIVALS
Every puzzle has a rival time to chase. Earn three stars by solving without
hints and beating the rival.
