Balance (puzzle) (original) (raw)

A balance puzzle is a mathematical puzzle which challenges the solver to distribute a subset of numbers so that the several sides of a stylized diagram representing a balance scale are equal. The balance puzzle is a classical number puzzle in the World Puzzle Championship.It consists of a mobile or tree structure, with designated positions where the player must hang specified weights, so that everything balances.See examples below. There are usually 8 to 12 consecutive numbers (weights) to place, which makes it much smaller than, for example, sudoku.
