633

633 is a simple symmetrical 4 object siteswap. Two balls go up and down at 6 ball height, one on each side of the pattern, while the other two balls are juggled low, like part of a 3 ball cascade. The first throw is a high, non-crossing throw from the right hand (a 6), and the next two throws are much lower, crossing throws (3s), about a 6th of the height of the 6s, one from the left hand and then one from the right hand. Then the same three throws are repeated on the other side, starting with the left hand throwing a 6. This pattern was known as "towers" before the invention of siteswap notation.
Before learning 633, you should already be good at the 4 ball fountain, 630, 603, 6330, and 6334.
