Gameplay
One continuous path. No second visits.
Each puzzle is a grid of sequence numbers with a marked start and finish. Move one adjacent cell at a time, keep the sequence honest, and cover the board in a single route.
Training
Practice anytime with custom difficulty and board rules. Training never touches daily leaderboards, so you can sharpen without pressure.
Encore
Finish every daily run in the UTC week to unlock Encore — an extra challenge for players who stayed the course.
Controls
Quiet tools for focused play.
The board stays central. Undo, Hint, and Restart sit under the grid for one-handed clears.

Harder difficulties favour longer routes, more turns, and tighter corridors. The canonical solution is never shown during normal play.
