Playground Differences

We invite you to the fun city Playground Differences, where only children live, and instead of streets and boring buildings, there are playgrounds with various attractions all over the place.
Periodically, new sites are being completed, but recently citizens have begun to notice that similar areas have appeared.
This did not please the small inhabitants of the game town.
They ask you to compare pairs of identical pictures, if you find the differences, they will leave them.
All you need to see ten places and find at least four differences.
