Color-Dot Puzzle
Generated browser dot images
Eight synthetic dot images are generated in the browser, each with a target digit. Choose what you see from randomized options; the result is only the raw number correct out of eight.
Your screen, its brightness, its color settings, and the light around you can all change how these images look. This puzzle runs in your browser. It is not a screening test for color vision, and it is not a diagnosis.
