Did you get it right?
This roller-rink skate-window puzzle asks you to compare panel A and panel B around the rental sign, shoe shelves, skates, ticket holder, and floor sign.

The Answer
The correct answer is: There are five visible changes in the skate-window scene..
Here is why
- Difference 1: The shelf number changes from 8 in panel A to 3 in panel B.
- Difference 2: The direction arrow on the floor sign points left in A and right in B.
- Difference 3: The lace loop on the skate being held changes shape.
- Difference 4: The ticket paper in the ADMIT ONE holder has a different torn top edge.
- Difference 5: The small star detail on the wall poster is different between the panels.
Why people miss it
The boy and clerk look very similar, so the real changes are easy to miss in the signs, shelf, and small skate details.
