Every breaker feeds exactly one room, and nobody labelled them.
The house is not tidy either: one room is fed by two
breakers, and one room is fed by none at all.
Flip whichever breakers you like, then press THROW.
The rooms fed by those breakers light up. That is one throw off your
budget.
Under each breaker is a blank label. Tap the label
to write on it which room you think that breaker feeds. When every breaker
is labelled, press RESTORE.
A wrong guess also costs a throw. Run out and the box
goes dark until midnight.
A room with two breakers lights from either of them, so it will not
behave like the others. A room with none never lights at all. Finding
which is which is most of the job.
Basic is four rooms. Hard
is six.
