Rooms on a side
Pick how many rooms sit on one side of the square. The number is rooms, not pixels — walls sit between rooms, so an N×N board draws as 2N+1 tiles across. Classic shows the map. Fog limits the lamp. Keys lock the exit.
Every board here is perfect: one route between any two rooms. Easy, Medium, Hard, and Expert are shortcuts into common size and mode pairs. Daily locks a twelve to the UTC date. Timed adds a sixty-second clock on twelve classic.
