Wirespan
Route power to every house with the least wire.
Every day: One power-line grid a day, the same for the whole world: connect every house to the plant with as little wire as you can. New puzzle: Midnight on your device clock.
Wirespan is a daily logic puzzle about building power lines. You place towers to carry power from a plant to every house, and shorter wires deliver more megawatts, so you keep rearranging to raise your score. The game is in English and many other languages, and the grid is the same for everyone each day.
About Wirespan
Wirespan is a browser puzzle credited to Derek Peterson, with its puzzle numbers counted from 1 January 2026. Its interface is in English by default and is translated into many languages, including French, German, Spanish, Italian, Dutch, Danish, Norwegian and Indonesian.
Each day's map has a power plant, some houses, open ground, rivers and ridges. You tap a square to build or remove a tower. Wires join anything within two squares, towers have to stand on open ground, and wires can cross rivers and ridges. Once every house is lit you have a solution, but not necessarily a good one: shorter wires deliver more megawatts, so you keep moving towers to improve your output.
Your result is shown in megawatts and compared with the engineers' grid, the best known layout for that map. You can study that grid afterwards, and the archive marks a day you studied. Ranks run from apprentice lineworker to superconductor. Besides the daily grid there are drills and a practice mode that deals fresh maps at any time, and settings for sound, haptics, reduced motion, high contrast and larger text.
Wirespan suits players who like optimisation puzzles where finishing is easy and doing it well is the real challenge.
How to play Wirespan
- Look at the day's map: the plant, the houses, rivers and ridges.
- Tap open ground to build a tower; tap again to remove it.
- Place towers so wires, which reach two squares, link the plant to every house.
- Once all houses are lit, keep rearranging to shorten wires and raise the MW output.
- Copy your result to share, and compare it with the engineers' grid.
Tips
- Wires cross rivers and ridges, so do not detour around them.
- Fewer, well-placed towers usually beat a long chain of short hops.
- Use practice grids or drills to test layouts before the daily one.
