About Duotrace
Duotrace is a chill but sneaky-tricky puzzle game. The rule is simple: trace every line in the shape exactly twice without lifting your finger. Sounds easy, until the shapes get tangled and you have to think ahead to find the path that works. What sets it apart is that double-trace twist. A small rule that becomes a real brain teaser, with a great "aha, got it!" feeling once you crack a level.
Fans of casual will feel at home, and the puzzle elements give it extra range. Pick it up for a short break or settle in for a while — it runs well on phone, tablet, and desktop alike.
If you want to do well, keep this in mind: Work from the corners and edges inward — they usually have the fewest possible solutions. Take a screenshot of a tricky board before experimenting, so you can always reset in your head.
Duotrace plays free in your browser on Glaze Games — one click and you're in, on any phone, tablet, or laptop, with no sign-up wall.
