Complete the pattern in the grid.
PlayMemorize Matrix is a free pattern completion game inspired by Raven's Progressive Matrices, one of the most widely used IQ test formats. You see a 3x3 grid with the bottom-right cell missing and must identify the correct piece from multiple options.
Multiple rule types. Patterns use five properties (shape, color, size, fill, count) applied across rows, columns, or diagonals. At higher difficulties, multiple rules combine for complex patterns that test fluid intelligence.
Five shape types. Circle, square, triangle, diamond, and star, each rendered with solid, outline, or half-fill styles. Three sizes and five colors create rich visual variety.
Part of the PlayMemorize family of free memory and brain training games.
Q: What is Matrix Reasoning?
Matrix Reasoning presents a 3x3 grid of shapes following a pattern, with the bottom-right cell missing. You choose the correct completion from multiple options. It is one of the best-validated measures of fluid intelligence.
Q: Is it free?
Yes, completely free. No account, no ads. Your high score is saved locally.
Q: How does difficulty increase?
Early rounds use a single rule (e.g. shapes change by row). After a few correct answers, two rules combine (e.g. shape by row AND color by column). At expert level, three rules overlap and you choose from 6 options instead of 4.
Q: What properties do the patterns use?
Five properties: shape (circle, square, triangle, diamond, star), color (5 colors), size (small, medium, large), fill (solid, outline, half), and count (1, 2, or 3 shapes per cell).
