Circuit Courier
Rotate wire tiles to power every bulb before the charge drains.

About Circuit Courier
Circuit Courier is a compact logic puzzle where you rotate wire tiles on a small grid so the current flows from a battery to every bulb before the charge meter drains. Each board mixes straight wires, corners, T-junctions, and the occasional cross piece. The first 30 seconds of every round are intentionally simple: a single battery, a single bulb, and three misaligned wires that show you what one tap can do.
Daily mode bundles five hand-authored boards picked deterministically from the UTC date, so every player sees the same set on the same day. Endless mode draws from the harder pool and tightens the charge budget the deeper you go. A clean clear awards three things: the base board points, a remaining-charge bonus, and a rotation-efficiency bonus that rewards solving with as few rotations as possible.
Boards are designed to run quickly on mobile. Tiles use SVG glyphs rather than canvas, so rotation animations stay sharp on small screens, and the layout reflows down to a 360px viewport. Daily completion, your current streak, and your high score live in local storage on your device. Nothing about your runs is sent off-device.
How to Play
- Tap any wire tile to rotate it 90 degrees clockwise. Battery and bulb tiles are locked.
- Connect the battery to every bulb. The current flows through wire edges that meet at a shared cell border.
- Watch the charge meter at the top. The board ends when every bulb is powered or when the meter reaches zero.
- Daily mode runs five boards in a row. Endless mode keeps going until you run out of charge.
- Use the keyboard if you prefer. Each tile is a real button, so Tab moves between cells and Enter or Space rotates.
Tips & Tricks
- Plan from the bulb backward. Every bulb has exactly one open edge, so figuring out which neighbour must feed it usually fixes a chunk of the path.
- Cross tiles never need to rotate. They always carry current on all four sides, so treat them as fixed waypoints when you trace the route.
- Corner tiles only have two edges. If a corner has to deliver current in three directions, you need a T-junction instead.
- Save rotations for the path you actually plan to use. Idly rotating dead-end wires costs you the rotation bonus at the end of the board.
Scoring
- Base board score: 100 points per cleared board.
- Charge bonus: up to 100 points based on the share of charge remaining when the board cleared.
- Rotation bonus: up to 100 points; the closer you stay to the optimal rotation count for the board, the bigger the bonus.
- Run total: the sum of the score from every cleared board.
Daily and endless
- Daily: five boards, deterministic by UTC date. Replaying the same daily does not extend your streak.
- Endless: hard-pool boards with a charge penalty that grows with depth. Use it for high-score chasing.
- Streak: only a fresh UTC daily clear with every board solved bumps the daily streak counter.
Use cases*
- Quick logic break: one daily set fits in a few minutes between tasks.
- Pattern-recognition warm-up: short rotations and a few rules of thumb make a fast tune-up.
- Friendly competition: the daily set is identical for every player, so scores compare cleanly.
- Mobile-friendly play: the grid reflows to small screens and only needs taps.
