Circuit Logic — Free Online Pipe Rotation Puzzle
Circuit Logic is an addictive puzzle game where you rotate circuit tiles to connect all paths and complete the circuit. With 65 free levels ranging from easy 4×4 grids to expert 8×8 challenges, it's a perfect brain teaser for puzzle fans of all skill levels.
How to Play Circuit Logic
- Click or tap any tile to rotate it 90 degrees. Some tiles are straight wires, others are bends, T-junctions, or crosses.
- Rotate tiles so that all paths connect to form a complete circuit with no loose ends.
- Every pipe endpoint must connect to another — no dangling wires!
- When all tiles are properly connected, the level solves automatically.
- Progress from simple 4×4 grids to massive 8×8 expert challenges.
Tips & Strategy
- Start from the corners and edges — these tiles have fewer possible orientations, so they're easier to lock in first.
- Work inward from solved tiles. If a corner pipe only goes two directions, one of them must connect inward.
- Look for straight-line segments — a row of tiles that must all point the same way.
- If you're stuck, try rotating a single tile and see how it affects the surrounding connections.
- Fewer moves = more stars. Plan your rotations to minimize unnecessary clicks.
