Duotrace

Duotrace is a puzzle game that feels calm at first, but it hides a clever twist underneath its simple surface. The main rule is easy to grasp: you have to trace every line in the shape exactly twice, and you cannot lift your finger while doing it. That sounds straightforward, right? But once the shapes start getting more tangled and complex, you quickly realize that this is not just about moving your finger along the lines. You have to think several steps ahead, planning your route carefully, because the wrong move can leave you stuck with no way to finish.

What makes Duotrace stand out from other puzzle games is that double trace mechanic. It is such a small change to the usual trace the line formula, but it turns every level into a genuine brain teaser. You will find yourself staring at a shape, trying to figure out the order of lines that lets you cover everything twice without backtracking into a dead end. And when you finally spot the path that works, there is that great moment of clarity, that satisfying aha, got it feeling that makes all the thinking worth it. NAJOX brings you this experience, where each level feels like a fresh little puzzle box waiting to be opened. The game does not rush you, so you can take your time, experiment, and enjoy the process of untangling each new challenge. It is perfect for players who like a quiet, thoughtful game that still gives their brain a proper workout.
