Visual Memory

Visual Memory is the spatial-recall cognitive test popularized by Human Benchmark. A grid of squares appears, some flash white for a moment, then go blank. This version follows the same idea with its own level progression. You click all the squares that lit up — without clicking any that didn’t. Each successful round adds another lit square; the grid grows as you advance.

How to play

• Click Start. The board displays a grid (3×3 to start).
• Some squares flash white for about 1.5–2 seconds (the flash gets a little longer as you level up). Level 1 lights 3 squares, and each level adds one more.
• Click every square that lit up. Correct = green, wrong = red.
• Three wrong clicks in one round costs a life, and the level restarts with a new pattern. 3 lives total.
• Clear all lit squares to advance. Your best level is saved in your browser.
• Grid grows: 3×3 (levels 1-2), 4×4 (3-5), 5×5 (6-10), 6×6 (11-15), 7×7 (16+).

Beginner strategy

• Chunk by position. “Top-left cluster + lone bottom-right” beats 4 separate positions.
• Use grid coordinates as anchors. “Row 2, column 3” is faster to encode.
• Look at the pattern, not the cells. Shapes are easier than positions.
• Click confident ones first. Certain clicks before uncertain ones.
• Don’t rush after the flash. Pause to consolidate.

Intermediate strategy

• Region-based memory. Top-left, top-right, etc. quadrants.
• Edge mapping. Edges easier to remember than centre cells.
• Cross-reference patterns. If lit cells form a recognizable shape, remember the shape.
• Click in same order. Encode path order = recall path order.
• Lives management. You can make 2 wrong clicks in a round for free; the third costs a life. Save uncertain clicks for last.

How you compare

Because this version uses its own grid sizes and tile counts, levels here don’t map directly onto Human Benchmark’s scale. The best comparison is against your own saved best level. The mechanic draws on visuospatial working memory, a well-studied idea in cognitive psychology.

FAQ

• Q: What’s tested? A: Visuospatial working memory.
• Q: How long is the flash? A: 1.6 seconds at level 1, growing by 0.1 seconds per level up to 2.1 seconds.
• Q: Best strategy? A: Chunk + shape recognition, not individual cells.
• Q: How to improve? A: Practice the chunking and shape strategies above, and pause after the flash before you start clicking.
