Before you start

• ✓30 pattern puzzles. Each shows a grid of figures with one missing. Pick the figure that completes the pattern. They start easy and get hard.
• ✓25 minutes. The clock starts after two practice puzzles. Most people use 15 to 20 minutes. You can skip, go back and change answers.
• ✓No penalty for guessing. A blank counts the same as a wrong answer, so answer everything.
• ✓Your score is free. Score, percentile and margin of error appear the moment you finish. No email, no card.

For a fair result: use a screen large enough to see the figures clearly, find 25 quiet minutes, and work alone without tools. Scores on phones tend to run a little lower.
