The mixed battery is the other great classic of intelligence testing. Where a matrices test speaks only in pictures, the battery Hans Eysenck popularised in his famous self-scoring IQ books throws everything at you under one clock — word puzzles, number rules and figure series, interleaved so you must keep switching mental gears. That switching is the point: general ability shows most clearly when no single trick carries you through.
This free test is the battery in miniature: twelve original puzzles — word bridges, anagram odd-one-outs, letter and number series, rule-linked number wheels, and figure sequences — in a gentle nine minutes. We score it the moment you finish and email you a free report with your level, a verbal / numerical / figural breakdown and where to focus next.
The full Classic 40 — forty items under the classic thirty-minute clock, exam conditions, worked solutions for every item and a classic-style scale estimate for your score — is available as the paid version of this test. Squizly is not affiliated with the estate of H.J. Eysenck or any psychometric test publisher, and this test is not endorsed by either; the historical name describes the format. Every puzzle here is an original item written in the classic mixed-battery style.
