Circuit Link is a rotation puzzle. The board is a grid of conduit tiles: straight pieces, corners and three-way junctions. Tap a tile and it turns a quarter turn. Your goal is to make one connected route from the yellow source in the top-left corner to the blue core in the bottom-right corner. Three boards make a run, and every rotation you use is subtracted from the score.
- A run is three boards: two 4 × 4 grids, then a 5 × 5 grid.
- Each board is worth 400 points, and every rotation in the run costs 10.
- A board is complete the instant the source connects to the core.
- Tiles turn clockwise only, and a straight piece has just two distinct positions.

Tap or click a tile to rotate it a quarter turn clockwise. The tile animates briefly, and you cannot rotate another tile until it finishes. Tiles connected to the source are lit, so you can always see how far the power currently reaches.

- Three boards, 15 rotations
- 1,050 points
- Three boards, 30 rotations
- 900 points
With three boards the most you can earn is 1,200, and every tap moves you away from that number. A rotation costs a fortieth of a board, so the score is entirely about solving with as few spins as possible.
Each board is generated around a guaranteed route from source to core that only ever steps right or down. Tiles on that route are chosen so they can connect; everything else is random. That means there is always at least one solution that heads steadily toward the bottom-right corner, without doubling back. Use that as your mental map: look for a staircase of tiles moving right and down.
A straight piece looks the same after two quarter turns. If a straight is wrong, one tap fixes it; a second tap just undoes the first. Never tap a straight twice in a row.
The lit tiles show the end of your current powered path. Work outward from there, one tile at a time, rather than fixing tiles in the middle of the board that are not yet connected to anything.
- Look at the source and the core, and sketch a right-and-down route between them.
- Prefer routes through tiles that already point the right way or need a single turn.
- Extend the lit path tile by tile from the source, counting turns before each tap.
- Ignore tiles off your chosen route; they do not need to be tidy.
- Stop as soon as the core lights up. The board completes automatically.
- Rotating tiles to see what they look like, which costs 10 points each time.
- Tapping a straight piece twice and ending up where it started.
- Trying to fix every tile on the board instead of one route.
- Choosing a route that needs several triple-turn corners when a simpler one exists.
Because everyone has the same 1,200-point ceiling, the leaderboards come down to rotation counts. Circuit Link's achievements progress from powering your first run to an efficient one to a nearly spin-perfect run. For the same move-counting discipline in a different shape, read the Tile Shift guide, or the Cipher Vault guide for puzzles where restraint with hints is rewarded.
Which way do tiles rotate?
Clockwise, a quarter turn per tap.
Is every board solvable?
Yes. Each board is built around a guaranteed route from source to core.
Do I have to connect every tile?
No. Only one connected path from source to core matters; the board completes the moment it exists.
Is there a time limit?
No. Only rotations affect the score, so take your time.
Verdict
Circuit Link punishes curiosity and rewards planning. Map a right-and-down route, count turns before you tap, and never spin a straight twice.
