Every breaker feeds exactly one room. Nobody labelled them.
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.
Par is the fewest throws that could possibly
work. Two throws can tell four breakers apart; three can tell eight
apart. Beating par is not possible. Matching it is the game.
Basic is four rooms. Hard
is six, and the extra room is worth a whole throw.
