One line.
Every cell.
In order.
Draw one line through the whole grid, hitting the numbers in order. New puzzle every day, and everyone gets the same one. Takes about two minutes. Some days it takes longer than you'd like to admit.
Launching soon on Android & iOS
The rules fit on four cards.
That’s the whole game. Solving it is your problem.
Start at 1
The line starts on tile 1 and has to end on the highest number.
Fill every cell
Your line passes through every cell exactly once. No gaps, no doubling back.
Numbers in order
Hit the checkpoints in order: 1, then 2, then 3. You can’t skip ahead.
Mind the walls
Walls block the way between some cells. Annoying at first, until you realize they’re telling you where to go.
One a day, plus extras.
Play it with your coffee, on the bus, wherever. Then check how everyone else did.
The Daily
One puzzle a day, same for everyone. We tune it so it puts up a fight without ruining your morning.

Streaks & stars
Solve daily to build a streak. Clean solves earn stars. There are achievements too, if you’re into that.
Practice mode
As many puzzles as you want. Grids get bigger and walls get meaner as you level up.
Puzzle packs
Extra sets of puzzles for when one a day isn’t enough.
Hints that help
Stuck? A hint erases your wrong turn and shows the next step. It costs you a star, though.
There’s already a puzzle for today.
Free, no catch. Coming to Android and iOS.
