About Duotrace

You trace lines through geometric shapes with one catch: every edge must be drawn exactly twice. Duotrace starts simple – a few nodes, a few connections – but ramps up as shapes overlap and paths weave through each other. The challenge is planning your route so you can double back over every line without painting yourself into a corner.

The double-trace rule turns familiar path-tracing into something fresh. Early puzzles teach the logic; later ones demand you map several moves ahead. When a tangled web finally clicks and you close the last line, the payoff is worth the head-scratching. Poki Games offers dozens of levels that keep the difficulty curve smooth but satisfying, so you always feel one puzzle away from your next breakthrough.
