TraceCircuit

Turn a web of lines into one continuous route. Trace every connection once, revisit nodes when needed, and find a finish that keeps the whole circuit connected.

Explore 90 fixed puzzles across four chapters: open routes, required starting nodes, ordered markers, and one-way lines. Each chapter introduces its rule with a simple circuit before adding more choices.

Drag from node to node to draw your route. Used lines stay visible, available connections respond as you move, and lifting your finger leaves the route ready to continue. Undo one line, drag back to revise, or restart after confirming. If a choice blocks the remaining route, review the missed lines and the node where progress stopped.

Use two levels of hints when you need a nudge. Get a starting-node suggestion, then ask for one next-line suggestion with a short explanation about remaining exits or direction. Hints never reveal the whole route.

After a clear, review your time, undos, hints, and personal record. Earn a mark for finishing without hints, save favorite circuits, and return for a daily challenge that rotates through the built-in puzzles.

Adjust node snapping, trail pattern, direction arrows, sound, glow, and the light or dark paper theme. A play guide explains the route rules, including why the number of exits at a node can affect a good starting point.
