About this tool
Test your working memory capacity — memorize colored shapes and recall their positions in increasingly challenging rounds.
The Visual Working Memory Test is a five-round change-localisation task: coloured shapes flash on a grid for between 1 and 3 seconds depending on difficulty, the grid clears, and you click the cells where they were. Each round scores as the percentage of target cells you recovered, out of 500 points total, and the result reports your memory span — the largest set size you recalled with no misses and no false clicks. It is a self-test and a game for anyone curious about their own visual span, not a clinical or diagnostic instrument.
Open Visual Working Memory Test on AltFTool — it loads instantly in your browser.
Pick a difficulty on the intro screen — Beginner (2-4 items, 3x3 grid, 3 seconds), Easy (3-5, 4x4, 2 seconds), Medium (4-7, 4x4, 1.5 seconds) or Hard (5-9, 5x5, 1 second) — then press "Start Memory Test".
After the countdown the coloured shapes flash for that level's display time; once the grid clears, click every cell a shape occupied and press "Submit Answer" — the recall phase is untimed.
Cells turn green for correct, red for wrong and orange for missed, and after 5 rounds "Test Complete!" reports your score out of 500, your memory span in items, best streak and correct rounds.
Alongside the score it reports the largest set size you recalled perfectly, which is the figure the underlying task is actually designed to estimate.
Difficulty raises the item count, shrinks the display time from 3 seconds to 1, and expands the grid from 3x3 to 5x5, so the task keeps loading memory rather than reaction speed.
There is no clock during the click-back phase, so the score reflects what you encoded rather than how fast you can move a mouse.
Commonly cited estimates fall in the region of four items, with a wider everyday range of about four to seven depending on how the task is run. This test reports your own span as the largest set size you recalled with no missed and no incorrect cells.
Each of the five rounds is worth up to 100 points, scored as the proportion of target cells you correctly clicked, for a maximum of 500. Reaching 90 percent is labelled Genius, 70 percent Excellent and 50 percent Good, and a streak counter tracks consecutive rounds with a flawless answer.
Beginner shows 2 to 4 shapes on a 3x3 grid for 3 seconds; Easy shows 3 to 5 on a 4x4 grid for 2 seconds; Medium shows 4 to 7 on a 4x4 grid for 1.5 seconds; Hard shows 5 to 9 on a 5x5 grid for 1 second, with nine distinct shapes and nine colours in play.
No. This is an informal browser game with no normed sample behind it, and results move with screen size, distraction, tiredness and how many times you have played. If you are genuinely worried about memory or concentration, speak to a doctor rather than reading anything into a score here.
