What online game is this? - ball puzzle game

I used to play ball online puzzle game, but I can not remember the name of the game or website.
You have to create their own levels and play levels that were submitted by others. We had to position and start the end position of the ball. Then set the level by using treadmills, teleporters, things to throw the ball a certain distance, etc.
If you have a level that the elements used by the Creator to get the ball had gone from beginning to end.
He also had a scoring system.
