1. What You're Solving
Circuit Flow is a path puzzle. Tiles hold straight pieces, corners, and T-junctions. Click to rotate them 90 degrees. When a tile touches a powered neighbor the right way, it lights up amber. Your job is to light a continuous route from the battery to the core.
Some tiles are locked. Build around them instead of fighting them. That constraint is most of the challenge.
Why the Last Click Feels Good
An incomplete path feels unfinished. When the final joint snaps into place and the whole line glows, that little tension drops. You don't need a research paper for that - it's the same feeling as finishing a jigsaw.
2. How to Think About the Grid
Don't rotate tiles at random. Trace backward from the core or forward from the battery and ask what orientation each tile needs. Mentally spin a piece before you click - fewer wasted moves.
3. Work Around Fixed Tiles
Fixed tiles won't move. Treat them as walls with a set direction. If the center is blocked, go around the edge. If a T isn't helping, a chain of L corners often will.
T Pieces
A T can feed three directions. Use it when one path needs to branch or when you need to pull power past a tight corner.
L Corners
Corners turn the path. Most clean solutions are a mix of straights and a few well-placed L turns.
Quick Start Habit
Before your first click, find source and sink. Sketch a rough route. Then rotate only the tiles that need to change. Whether it takes five moves or fifty, lit path = win.
