The original ruleset by Naoki Inaba (transcribed below) did not contain numbers (requiring always exactly 1 light bulb per region).
The implementation generalises the original ruleset, following an idea that appeared in the latest WPC booklet (October 2024).
These puzzles were kindly transcribed by PinkHoodie.
