how do you do gravity wells?

you have to have the line rider dude have his front end in the air then put aline close to his sled at its highest point , but make sure that the blue side not the black side is facing him. that way the line rider dude will be pulled to the top, or something like that

no... no... no...
*facepalm*
It's actually pretty complicated. If one of the 'points' is below a line it gets pulled up. There are 'points' at the shoulder, both hands, the butt, both feet, the two pegs of the tail, the place where the string meets the sled, and a little in front of where the sled just starts to curve. Bosh is connected to the sled by the string and his butt. The butt connection is stiff and the string is loose (both are elastic). when the different points get pulled in certain directions these connections are stressed in diff ways, sometimes pulling bosh off of the sled. the farther a point is from the line, the stronger the well, but the well will also have a harder time activating. The bigger the line is, the easier it is to connect. There is a maximum distance for wells. The wells in the online beta tests activate over 1 frame. The mobile wells are very weak and constantly activate. It takes a lot less accelleration in the mobile version to rip bosh off of the sled than it does in the online betas.
