Nobody leaves the Weigh House without their order. You are the workshop's assayer: people bring you scales, mobiles and levers, and you have to set them level using the weights on the counter. Each order takes one to four minutes.

A ledger of 80 orders
Pans: two sides, the same weight.
Mobiles: scales hanging from other scales.
Levers: what hangs far from the center weighs more.
Balloons: pieces that pull upward and subtract.
Combinations: everything you have learned, at once.
Drag each weight onto an empty hook: the scale tilts and its needle, the fiel, shows you which way it is going. Every order has exactly one solution. Solve it on the first try, without moving a weight twice, and the workshop seals it in wax.
