TraceCircuit

Trace a route through a network of nodes and touch every edge exactly once.

This quiet, focused puzzle is made for short sessions. Each circuit takes a minute or two to read, test and solve. Drag from node to node to leave a bright ink trail. The line you have used disappears from the choices, while ordinary nodes can be visited again when the remaining route allows it.

Work through 90 handcrafted circuits across four chapters:

• Open paths let you choose your starting point.
• Chosen starts ask you to read the marked opening node.
• Sequence nodes add numbered discoveries to the route.
• One-way edges introduce arrows that must be followed in the right direction.

The board keeps your current trace when you lift your finger. Undo one segment at a time, ask for a focused hint, or finish the attempt to review the decision that closed the route. Successful runs record your time, undo count and hint count, with personal bests stored locally.

Use the daily circuit for a dependable offline challenge that rotates through the built-in puzzle set. No account, network connection, advertising, payment or external content is needed.
