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 sit about an arm's length from the screen.
- Follow the blue dot with your eyes and keep your head still.
- When the dot turns amber with a white ring, tap the play area or press Space.
Levels and scoring
A game lasts 2 minutes, split into six rounds of 20 seconds. Each round has its own path (a circle, side to side, a figure of eight, up and down, loops and a wandering path) and the dot moves a little faster each time. The time you have to catch a change also shrinks, from 1.4 seconds in round 1 to 0.75 seconds in round 6. A catch scores 10 points, plus up to 10 more the faster you are. Tapping before the dot changes costs 5 points, and a change you miss scores nothing. The end screen shows how many changes you caught, your average catch time and your early taps.
Tips for a high score
- Follow with your eyes, not your finger. Rest your thumb or mouse near the middle of the play area.
- Wait for the amber ring. Early taps cost points, so don't tap on a hunch.
- Keep your head still and let your eyes do the following.
- Mute notifications for two minutes. Pop-ups pull your eyes away at the worst moment.
- If moving shapes make you feel dizzy or queasy, stop and play Shade Hunt instead. If your device asks for reduced motion, the dot moves more slowly.
