How to play Circuit Paths

Circuit Paths is a whole family of puzzles built on one idea: divide every dot on the board into separate paths. In the classic version there are 66 dots — 22 solid and 44 white — to split into 11 paths of six, each running solid → white → white → white → white → solid.

The other types change the rules but not the idea: colour pairs to join, numbers that give each path’s length, white dots whose values must add up to a target, letters that spell words, paths that must turn exactly twice or visit two regions, closed loops, bridges where two paths can cross, hexagonal boards and freeform networks.

Every puzzle is made solution-first and checked by an exact solver, so it has exactly one answer. Hints never just copy the answer: they find forced paths, forced steps and contradictions, and explain them. The creator lets you build your own, export them as JSON, and share a link.

How to play Circuit Paths

Divide every dot into separate paths; each path follows the rules for length, endpoints and anything else the puzzle sets.

The rules

  1. Every playable dot belongs to exactly one path. No dot is shared and none is left over (unless the puzzle says some may be).
  2. Paths move along allowed connections — across and down on a grid, six ways on a hexagonal board, along the links on a freeform board.
  3. A path starts and ends on endpoint dots and never passes through one. Internal dots join exactly two neighbours; endpoints join one.
  4. Each type adds rules: a fixed length (Classic: six dots), matching colours, endpoint numbers that give the length, target sums, rising numbers, exact turns, regions to visit, words to spell, or closed loops. Bridges and tunnels let two paths cross.
  5. More types: triangle boards; two floors joined by lettered lifts; branching networks (only ✚ junctions branch, and in Network Junctions a network may also close a loop); Match Up (join each question to its answer); Double Lengths (one path is twice as long as another); One-Way Streets (all the arrows on a path point the same way); Hidden Ends (any dot may end a path, but grey stop dots can only be ends); Odd Dot Out (exactly one dot can’t be used); and Cheapest Routes (any valid answer, but aim for the lowest cost).

Playing here

  1. Choose a puzzle type and size, then press New Puzzle. The rules for that type are written under the board.
  2. Drag from dot to dot to draw a path. Drag back along it to rub out. Tap a path to select it and press Delete, or double-tap / right-click a dot to clear its path.
  3. Every dot must end up on exactly one path, and every path must follow the rules — the right length, the right endpoints, and any sums, words, turns or regions.
  4. Mistakes get a specific message (“This path contains seven dots; it must contain six.”). Hint and the Genie explain the next forced step. 📽 Present makes the board big for a classroom screen.
  5. Choose Board shape: Symmetric for boards with a symmetric outline. In networks, only the ✚ junction squares may branch; in cost challenges any valid answer solves it, and the aim is the cheapest.

Questions

Is there always exactly one answer?

Yes — every generated puzzle is checked by the solver. Locked segments (drawn thicker) are added only when needed to make the answer unique.

Can I make my own?

Yes — open the Creator: build a board, set the rules, draw a hidden solution, derive the clues, make it unique and export or share it.

What is Present mode?

It hides the side panels and makes the board as big as possible, for teaching on a projector or big screen.
