This hidden-number puzzle combines several digits inside one overlapping drawing.
At first glance, most people immediately notice the numbers 6, 8, 4, and 1. However, the curves, loops, diagonal lines, and shared strokes hide several additional digits.
The intended solution contains all ten digits:
0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
That means the correct answer is 10 different numbers.
Some digits are much easier to recognize than others because several of them share the same lines. Viewers may count more if they include repeated loops, but the standard answer counts each unique digit only once.
