Play Circuit
Circuit is a sequential path puzzle: draw one wire that hits the numbered checkpoints in order and visits every cell on the board exactly once. No diagonals, no crossings, and no cell left out. Finishing early with squares still empty means the route is wrong.
How to play
Draw a wire through every numbered checkpoint. Start at 1 and visit 2, 3, … in order. You may step up, down, left, or right — tap, drag, or use arrow keys.
No diagonals, skips, or leftover cells. You cannot jump diagonally, skip a checkpoint, reuse a cell, or leave any square unwired. The path is a Hamiltonian tour of the grid.
Rewind by stepping back onto the wire. Tap a cell already on your path to rewind to that point. Hint only marks a cell that can still finish the board from here.
Do not isolate a cell. You cannot leave a square with no orthogonal exit. If a cell is stranded, rewind — isolation is usually one wrong turn ago.
