Balance (Scales) Game Practice

Arctic Shores' Balance task, as candidates describe it, is a set of scales holding shapes with hidden weights. A few scales are shown already balanced; from them you work out what to put on the empty pan of the last scale so that it balances too. It is a numerical and logical reasoning task with right answers, and it adapts: solve one and the next is harder, miss one and it gets easier.

How this practice version works. Ten puzzles, a minute each. Read the balanced scales, then build the empty pan from the tray of shapes — any combination that weighs the same is right, except copying the full pan across. Difficulty runs from two shapes and one scale up to four shapes and four scales where you have to combine them — sometimes with the same shape on both sides, to cancel out. Your score is the sum of the levels you solved, so harder puzzles count for more.

What helps: pick the lightest shape as your unit and rewrite every other shape in it. "A triangle balances two circles" makes a triangle 2; then "a square balances a triangle and a circle" makes the square 3. If a ratio comes out as a half — two triangles balance three circles — use half a circle as the unit instead. Once everything is in units, the last scale is addition.
