Loop
One line. Every number. Daily.
Start at 1, finish on the highest number on the board, and cover every cell exactly once without crossing your own path. Loop pairs a deceptively simple rule set with a real difficulty curve — Easy, Medium, and Hard boards genuinely play differently, with sparser numbers and zigzagging walls that force real backtracking.
How to play
Press and hold the first cell and drag — your line has to end exactly on the highest number on the board.
Numbers only connect in order, so a wrong move simply won't register and you'll know immediately.
Cover every cell exactly once without crossing your own path or the walls that carve up harder boards.
Why people stick with Loop
Daily puzzle & streaks
A fresh puzzle drops every morning. Build a streak, get reminders before it breaks, and use a streak freeze to cover a missed day.
A difficulty curve that means it
Easy, Medium, and Hard are genuinely different boards — sparser numbers, longer routes, and zigzagging walls that force real backtracking on Hard.
Hints that actually help
Stuck? A hint rewinds your line to the last point a solution was still possible, then shows you the way forward.
200+ levels, never a rerun
Every board is generated and verified solvable on the fly — no two puzzles feel like the same layout.
