Clock Series

medium

Watch the hands move through a sequence of clocks and pick the next one.

How to play

You'll see a short sequence of clock faces. Figure out how the hour and minute hands are moving from one clock to the next, then pick the clock that continues the pattern.

Look at how both the hour and minute hands change between clocks in the sequence.
The rule is usually a fixed rotation or offset applied at each step.
Pick the option that keeps that rule going for the next clock.
Difficulty ramps up automatically as you answer correctly.

Why this matters

Clock-based series are a visual variant of the abstract sequence-completion items used to gauge fluid reasoning on tests like Raven's Progressive Matrices — the pattern lives in the relationship between steps, not in any single clock. Read more about the Raven's Progressive Matrices.
