Gilligan's Box is an odd
variation of the Box that combines portions of the Burst Box with an
additional vertical throw that is not paired with any horizontal pass. This
gives the pattern a more relaxed cadence, while also offering more variety
to the normally rigid Box siteswap. Because this trick includes parts of the
Burst Box, it helps to already know the Broken or Burst Box patterns before
attempting Gilligan's Box, though this is not required.
To learn Gilligan's Box, start with two balls in your dominant hand and one ball in your non-dominant. Make a fountain-style (where the ball travels in a circle rather than along a single vertical column) throw from your dominant hand, and then follow it up with a second fountain throw from your dominant hand paired with a horizontal pass from your non-dominant hand to your dominant hand. As that pass is being made, cross your non-dominant hand underneath your dominant hand, and then use it to catch the first fountain throw. At this point, the second fountain ball should be descending toward your dominant hand. To clear space for the catch, make a fountain throw from your dominant hand, while also simultaneously uncrossing your non-dominant hand. Catch the second fountain throw in your now empty dominant hand, and then catch the third fountain throw in your dominant hand.
Practice this on both sides. To run the full Gilligan's Box, simply make a fountain throw from your non-dominant hand, after it uncrosses, paired with a horizontal pass from your dominant hand. This will set you up for a new cycle on the opposite side of your body.
