Odd One Out
IntellectualNine abstract objects share a hidden rule — spot the one that breaks it, fast. Replicates the cut-e (Aon) scales ix inductive reasoning test.
Overview
Odd One Out measures inductive reasoning: the ability to discover a rule in unfamiliar visual material and spot where it is violated — quickly. Each item presents nine abstract objects; eight obey a common rule and exactly one breaks it, and every item is procedurally generated so no two runs repeat. It replicates the presentation of the cut-e (Aon) scales ix ("Discovering Rules") test used in airline and corporate selection: nine objects per item, a 5-minute / 20-item pace, and correct-minus-incorrect scoring that penalises guessing. Difficulty progresses from salient rules (shape, shading, dot count) through subtler ones (position, size, dot style) to relational rules where what matters is how an object's parts relate to each other.

Example: which object breaks the rule?
Nine abstract objects share one common rule — exactly one breaks it. Scan for what all of them have in common, then find the exception. The odd one out is highlighted below.

Game Phases
Configure
Choose your difficulty and test duration. Longer tests draw more items and have a higher target score.
Discover
Scan the nine objects, induce the rule they share, and click the one object that breaks it — keys 1–9 work too.
Review
Afterwards, revisit every item with the odd object marked and the rule it broke explained.
More Practice
Abstract Reasoning
8 exercisesNon-Verbal Reasoning
Spot the rule in a set of abstract figures — pick the odd one out, the option that completes the pattern, or the true rotation of a figure. Tests non-verbal, fluid reasoning under time pressure.
Figural Analogies
Work out how the first shape becomes the second, then apply the same transformation to the third shape and pick the figure that completes the analogy. Tests non-verbal, abstract inductive reasoning under time pressure.
Rule Application
Hold a small rule-set in mind and apply it to a fast stream of coloured symbols — press the response each rule dictates before the window closes.
Matrix Transformations
Discover the hidden rule linking two example symbol grids, then mark exactly the two of four candidates that follow it — the real cut-e (Aon) scales clx screen, in its official 6-minute length. A classic pair-transformation mode remains as the practice variant.
Grid Classification
Six example tables, two hidden classes — deduce the rule that separates them and assign new tables to the right class. Adapted from the cut-e (Aon) scales cls format, including an Assessment Format mode that mirrors the real screen: four unmarked tables per item, 12 items in 12 minutes.
Switch Challenge
Deduce which numbered operator — a digit code that reorders a row of symbols — turns the top row into the bottom row. Replicates the cut-e (Aon) switchChallenge from the smartPredict battery.
ENAC Figure Matrices
A 3 × 3 matrix of figures with the bottom-right square missing, and 8 options to complete it. The rules run along the rows, down the columns and across the diagonals, and a board often has two or three at once. The exam format is 30 boards in 30 minutes, and you can move between boards and change your answers until you hand in.
ENAC Law and Anti-Law
Three numbers, words or figures obey a hidden law, and three don't. Under them are 8 propositions: tick every one that obeys the law. Numbers, words and figures are mixed through the run. The exam format is 35 boards in 30 minutes, and you're free to move between boards and change your ticks until you hand in.
