Afterimage

A silhouette flashes like a camera. Then pick it out of four look-alikes.

Once it starts, it counts — leaving partway scores 0.

How it works

  1. Five short visual tests a day, picked from a pool of ten: estimation, color, memory, proportion, tracking, shape, search and pattern.
  2. Everyone gets the same five tests, in the same order, with the same layouts.
  3. Each test reads its brief first, then runs once. Every test is worth 100, for 500 a day.
  4. Speed isn't scored — accuracy is. Take your time where the test lets you.
  5. These are games, not eyesight tests. Screen size, brightness and color settings all play a part.
