How to Play
- Spot your fish
One fish glows for a moment.
- Follow it
Every fish turns identical and the tank starts moving.
- Pick it out
When they stop, tap the one fish you were following.
Fish Tracker
One fish is marked. Then every fish looks the same and they all start swimming. Keep your eyes on that one fish.
Ready to test your tracking?
Watch the one marked fish, follow it through the slower-moving shoal, and pick it out when everything stops. A short chime plays when you start; sound is optional.
Nothing is hidden — the fish never change. Only your attention can slip.
What It Challenges
- Selective attention
Keep track of one fish among moving distractions.
- Sustained focus
Stay locked on for the whole crossing.
- Spatial tracking
Follow a path, not a picture.
