CONSTELLATION

Each star says how many light bridges must touch it. Bridges run straight, never cross, and at most two join any pair of stars. Light the whole constellation into one connected network.

You will never have to guess. Every board is generated and then run through a solver that only makes forced deductions — if the solver cannot finish it by logic alone, the board is thrown away and regenerated. That check is part of the build, so a guessy puzzle cannot ship.

Three sizes and a daily board that is the same for everyone.
