How to play
Drag from a power source across grid cells to a bulb. Wires cannot cross. Sources can split by branching the wire. Bulbs need their minimum current to light. Solve by lighting all bulbs.
Game features
- Power-flow rule with current splitting
- One hundred levels across four difficulty bands
- Daily puzzle mode with shared leaderboard
- Touch drag-to-route input
- Mouse-drag also supported
- Local solve-time tracking
Editor review
Circuit Trace is a logic puzzle where you connect power sources to bulbs by tracing wires across a grid. Wires cannot cross, and each bulb needs power from a source that may split among multiple wires. The format is reminiscent of Free Flow but with the added power-source mechanic.
What works is the power-flow rule. Each source has a fixed output current. Bulbs require specific minimum currents to light. When a source splits among multiple bulbs, the current divides. This introduces a quantitative dimension that pure routing puzzles lack, and the quantitative constraints make the late-tier puzzles truly deductive rather than just spatial.
One hundred levels arranged in four difficulty bands. The first band teaches single-source-single-bulb routing. The second band introduces splits, the third band adds source-current limits that force tight allocation, and the fourth band layers in obstacle cells that block wires.
Tested over five commute sessions. Touch with drag-to-route works fine. Mouse-drag also works. Keyboard is not supported. Both touch and mouse inputs are comfortable.
Where the design earns its three-and-a-half is the daily puzzle mode. Every player gets the same puzzle and times are shown on a leaderboard. The daily-puzzle retention pattern works here because the format has enough depth to support repeat play.
Where I would push back is the visual feedback during routing. When a route is invalid, the game shows a generic error message without explaining which constraint was violated. A clearer error message (insufficient current or route blocked, for example) would speed up learning.
Three-and-a-half stars. Solid power-routing puzzle with daily-puzzle retention loop. Worth playing for the format; better error messages would have lifted it higher.
