Tap between two stations, or drag from one, to add a beam. Tap again for a double, once more to clear.
Tap between two stations, or drag from one, to add a beam. Tap again for a double, once more to clear.
The field is full of relay stations, and each one shows how many beams it needs. Link them into a single network: beams run straight along a row or a column between two stations that can see each other, a pair of stations can share one beam or two, and beams never cross each other or pass through an asteroid. When every station has exactly its number and the whole network is connected, the signal goes through.
Every puzzle has exactly one solution, and it can be found by deduction alone: a solver checked that no guessing is ever needed. The par is the number of beams in the solution, so a solve without a single wrong beam matches it for three stars. A new network goes up every day at midnight your time. Monday's field is a small 7×7, and each day adds stations, loops and asteroids up to the 11×11 Sunday network.
