Odd One Out · Verbal Reasoning Test
Four words. Three share a category — the fourth is an impostor. Tap the odd one out, as many as you can in 60 seconds.
How to play Odd One Out
Each trial deals four words: three from one category (say, tools) and one intruder. Tap the word that doesn't belong. Correct answers score +1, wrong picks cost 1. 60 seconds.
What it measures
Odd-one-out classification is a staple of verbal reasoning assessments. Each trial makes you retrieve what the words mean, infer the hidden category, and test the outlier against it — semantic memory and abstraction working at speed.
Honest note: This leans on vocabulary and English-language categories, so it measures verbal knowledge as much as reasoning speed. A low score in a second language says nothing about your intelligence.
What's a good score?
Around 12 is typical; 20+ means your semantic network is fast as well as accurate. The percentile we show is an estimate based on typical distributions, not a clinical norm.
FAQ
Some categories feel debatable — what gives?
We keep categories deliberately clean (fruits, tools, birds), but language is fuzzy at the edges. If a set made you argue with the screen, that hesitation is itself the reasoning workout.
Does this improve my vocabulary?
It exercises retrieval of words you already know rather than teaching new ones. For building vocabulary, reading beats any game — including ours.
