I have completed a project and uploaded to website. I can find it in my account. Can someone tell me how i can share the link with my friend, like /projects/XXXXX … Many thanks.

So once you have created it, AND shared it with the community, you can copy the link at the address bar for that game (or have your friend go to your account), then give it to them. Then they will be able to play the game.

Also, please ask questions like this in the “Questions About Scratch Topic,” the show and tell is for sharing your games/studios.

It really works! Thank you so much! @DrChicken24
