Clock Series

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.
