Ocufuse games are for fun and screen breaks. They are not a vision test and do not diagnose or treat any condition. See an eye care professional for any concerns.
How to play
- Press Start and look at the cross in the middle of the play area.
- Without moving your eyes, watch for the amber diamond that flashes near an edge.
- Tap that edge of the play area, or press the matching arrow key.
Levels and scoring
A game is 30 flashes in six levels of five, which takes about 90 seconds. Levels 1 and 2 use only the left and right edges; from level 3 all four edges are in play. Blue circles join as decoys from level 2, up to three at a time, and the flash gets shorter, from 0.7 seconds at level 1 to 0.2 seconds at level 6. You have 2.5 seconds after each flash to answer. A right answer scores 8 points plus 2 for each level, so 10 points at level 1 and 20 at level 6. Wrong or missed answers score nothing.
Tips for a high score
- Keep your gaze on the cross. If your eyes jump to the edge, the flash is usually gone by the time they land.
- Sit centred, so all four edges are about the same distance from your eyes.
- On a large monitor, sit a little further back so the edges are not too far out.
- Look for the colour first: the diamond is amber and the decoys are blue.
- Blink between flashes. Staring without blinking dries your eyes out quickly.

Does it work on my phone?
Yes. It works in any up-to-date browser on a phone, tablet or computer, with touch, a mouse or a keyboard. The game pauses by itself if you switch tabs.
Is Edge Spot a peripheral vision test?
No. Edge Spot is a game, and a score cannot tell you anything about your field of vision. Screen size and how far you sit change it a lot. If you notice shadows, a curtain or missing areas at the side of your vision, see an eye care professional straight away.
Why does it matter where I look?
The game is about noticing things at the edge of your view while your eyes stay on the cross. If your eyes jump to the edges, the flash is usually gone before they arrive.
