Firstly, you go to the scratch search bar and enter any game you really like but aren’t able to make, because it is so difficult. This is demonstrated in the picture below.
Many different games should come up. If they don’t, it means that no one has made the type of game in Scratch.
Next you click on the game you like and wait till the game appears. There should be a Remix button hyperlink. You click on the Remix button.
Now it will say remixing. This is demonstrated in the image.
When you click on my stuff, you will see the game you have just remixed. The person who has made the game still has it. It is just that you have the same copy as them.
