TraceFlow

Turn a network into one continuous route.

This offline puzzle game is built for short sessions of focused route planning. Read the nodes, choose a legal start, and drag through each connection without using any edge twice. Nodes can be revisited when the network allows it, so every decision matters.

Explore 90 handcrafted levels across four chapters:

• Open paths: learn the core rule and find your own starting point.
• Starting point: begin from a clearly marked node and plan around the exits.
• Marked sequence: visit numbered nodes in order while keeping the route open.
• One-way links: follow arrows and respect direction as the network tightens.

The board keeps your trail visible as you play. Nearby nodes are easy to catch, used edges stay visibly marked, and Undo removes only the last segment so you can test a better choice. Hints explain whether to protect a remaining exit or respect a directional limit without revealing the whole answer.

When a route closes, the failed trail remains available for review. Complete routes show your time, undo count, hint count, and progress through the map. A rotating daily challenge uses the built-in level set and works without an account or an internet connection.

Progress and preferences stay on your device. There are no accounts, ads, payments, rankings, or external content.
