Why it’s different
A new puzzle, every day
One daily puzzle, the same for everyone, renewing at midnight UTC. Build a streak, then compare routes with friends using a spoiler-free result that never gives the words away.
Play as much as you like
Unlimited practice puzzles whenever you want them, across three to six letters, tuned to how you are actually playing.
Every puzzle is provably fair
Before a puzzle reaches you it’s checked against the full dictionary: a route exists, and it’s the shortest one possible using ordinary words. No obscure words required.

Built with care
Light and dark themes that follow your phone, haptics you can turn off, reduced motion if you want it, and a board designed to be read at a glance on a warm paper canvas.
Family-safe words
41,400 words, curated: no filler, no nonsense entries, nothing you wouldn’t want a child to spell.
Free. Complete. No catch.
