What is sequence completion?

Sequence completion is the ability to identify patterns in a series and predict what comes next. It is a fundamental measure of fluid intelligence (Gf) — the capacity to reason about novel problems without relying on prior knowledge.

Are sequence puzzles used in IQ tests?

Yes. Matrix reasoning and sequence completion tasks appear in major IQ assessments including Raven's Progressive Matrices, the WAIS, and the Stanford-Binet, where they measure fluid and abstract reasoning.

What types of sequences appear in the game?

The game includes arithmetic sequences (e.g., +3 each step), geometric sequences, alternating patterns, and abstract visual pattern sequences depending on difficulty.

Is Sequence Completion free?

Yes, completely free with no account required.
