Complete the pattern! You'll see a matrix with a missing piece — identify the underlying rule and select the correct completion. This non-verbal reasoning task measures your ability to identify patterns, deduce rules, and apply logic. Used in intelligence testing to measure fluid intelligence and abstract reasoning ability.
How to Play
- Each grid follows a hidden rule across rows and columns.
- The bottom-right cell is missing — choose it from 4 options.
- Rules grow harder: color, shape, count, rotation, then combined.
- 30s per puzzle; 3 wrong answers ends the game.
Scoring
- Correct = clamp(1000 − rt, 100, 1000) × difficulty (1.0–2.5).
- Wrong or timeout = −100.
- Total = sum of all puzzles.
Tips
- Scan one attribute at a time (color, then shape, then count).
- Check both the row and the column of the missing cell.
