Did you get it right?
Count the real sheep on the hillside pasture, not the painted sheep on the sign.

The Answer
The correct answer is: 13 real sheep.
Here is why
- Count the sheep spread across the hill.
- Do not count the painted sheep on the sign at the lower right.
- The real sheep are spaced apart so they can be counted one by one.
Why people miss it
The hill, barn, and sign all look friendly and calm, which makes it easy to skip the painted sign sheep or miss one of the real ones.
