Wirespan

Wirespan asks you to power every house from a plant with the least wire possible. You build or remove towers on open ground, and then improve the layout after all houses are connected.

1. Read the day’s grid and locate the plant, houses and usable ground.
2. Tap to build or remove towers; wires connect anything within two squares.
3. Power every house, then rearrange the layout to shorten wires and raise the delivered output.

It is a compact optimization puzzle for players who like a clean first solution and an even cleaner second pass.

The interface exposes three live measures: towers built, houses powered and output in MW. Its rules state that shorter wires deliver more MW, so a solved grid can still be improved.

Today

Drills

Practice drills offer a fresh grid at any time.

• Finish the connection first, then optimize: the site explicitly lets you keep tuning after every house is lit.
• Use a tower only when it creates a useful two-square connection; surplus towers can lengthen the network.
