Seattle Stack

Francis Favorini (in animation) came up with this variation while working on the Georgian Shuffle.

The throwing order is right, left, right, left.

Every throw is a multiplex throw. The hand that just threw reaches over the top to catch the first ball out of the multiplex.

Quote from Mr. Favorini:

"If you do it smoothly, the balls kind of form a stack down the center through which the balls cycle."
