👀 How to Play
- Look at the grid without zooming.
- Scan in blocks, not line by line.
- Focus on the shape:
- 8 has two closed loops.
- B has a straight vertical spine with two curves.
- Try to spot B before time runs out.
- Stop when your timer hits 5 seconds.
🎯 Why This Illusion Is So Tricky
Your brain is wired to:
- Group similar shapes
- Auto-correct what it sees
- Skip tiny differences
That’s why B can hide among 8’s unless you stay fully focused.
These challenges help to:
- ✅ Improve concentration
- ✅ Train visual discrimination
- ✅ Boost scanning speed
- ✅ Sharpen attention to detail
🧩 Did You Find It?
Be honest.
Did your eyes catch the B among all those 8’s?
If yes — excellent!
If not — don’t worry. Most people need a second try.
Scroll only when you’re ready.
