What is distinct here

Circuit Trace asks for one continuous route through numbered relays without revisiting a cell. Relay order adds a readable constraint to pathfinding, while the visible board keeps failures attributable to the chosen route.

Rules

  1. Start at S and move only to an orthogonally adjacent open circuit cell.
  2. Visit relay 1 and then relay 2 before reaching F.
  3. A traced cell cannot be visited twice; finish quickly and use fewer undos for a higher score.

Strategy tips

  • Read the whole corridor before moving so you know where each turn leads.
  • Undo immediately after a wrong turn; every undo costs points but preserves the puzzle.

What we tested

Each board ships with a verified route and supports all eight rotations and reflections plus reversal. Tests check adjacency, walls, relay order, revisits, backtracking, end conditions, pointer tracing, keyboard movement, pause and reset.

Frequently asked questions

Is every Circuit Trace puzzle solvable?

Yes. Each board is generated from a continuous tested route, then rotated, reflected or reversed for variety.
