Puzzle Time

12 Weighty Balls

You have 12 balls of identical size and appearance, but one of them is a slightly different weight—it could be heavier or lighter. You have a set of balance scales, as shown below, which will give three possible readings:

Left = Right

Left > Right

Left < Right

You have only 3 chances to weigh the balls in any number and combination of your choosing, using the balance scales.

You need to find which ball is the odd one out and confirm whether it is heavier or lighter than the rest.

How do you do it?

Solution: Weigh two groups of four, then two groups of three, then two singles… but which ones?! For one possible explanation, watch this short video on YouTube: 12 Balls Puzzle

If you enjoy solving puzzles, Alex Bellos sets a challenging puzzle like this in The Guardian every two weeks.
