Turn a quiet moment into a route-solving session.
Connect every line in a network with one continuous trace. Each line can be used only once, while ordinary nodes can be revisited. Choose a starting node, read the structure, and plan your route before the network closes behind you.
The puzzle collection grows through four rule chapters:
• Open starts let you explore the fundamentals.
• Starting point networks ask you to begin at a marked node.
• Marked order networks add checkpoints to visit in sequence.
• One-way links introduce arrows that must be followed in the right direction.
Every board is stored locally and works without an account or an internet connection. Drag between connected nodes, use Undo to remove the last segment, or restart when you want a clean attempt. Hints explain the reason behind a safe next choice without revealing the complete route.
After a route is complete, review your local progress and earn badges for solving without a hint. A daily challenge rotates through the built-in networks, so it remains available offline and does not require a service or login.
