Algodoo

The first version of this scene was posted on Algobox 10 days ago and was removed because it was regarded as a “voting”or “signup”scene. After examination, I think it is likely that the sign "Who will win"at the beginning caused the problem. I added it in the scene because it appears in many marble race videos. However, when uploading this scene, I did not take into account that it appeared on the cover of the scene, which makes this scene considered to be a “voting”or “signup”scene and has a bad impact on Algobox. In this version, I removed this misleading sign and reuploaded it after carefully checking the scene and introduction according to Algobox's rules. Because I really want people to see my work, I don't want to spend days of time and energy in vain. For every scene I upload after that, I will check them according to Algobox’s rules to make sure the same thing doesn't happen again.
I hope you can take my experience as a lesson, but also hope that administrators can understand.

This is the best!
