Here are 15 “Which one doesn’t belong?” puzzles.
In each case, we present five Scrabble tiles or groups of tiles. Your job is to discover the common pattern that four tiles exhibit and then identify the tile or assemblage of tiles that doesn’t fit. For example, for the series A, B, C, D, R, the simplest pattern is the first letters of the alphabet. R, then, is the tile that doesn’t belong.
We designed many of the puzzles to be in the wheelhouse of financial professionals. We will start with simple patterns and then get increasingly complex. Some of the items require specialized knowledge. To make it a bit easier, each puzzle is introduced with a hint.
The puzzles are designed to have one elegant solution. The reality is that every “Which one doesn’t belong?” puzzle admits to multiple solutions. If your solution is as elegant and satisfying as ours, please tell us about it. If you can answer 10 of the puzzles, you’re doing great. Enjoy.
