     The Four Ball Stacked Box is a variation of the Four Ball Box that can best be conceptualized as juggling a small Box underneath a much taller one. This pattern is sometimes referred to as just the Four Ball Box, but I arbitrarily chose to call (6,2x)(6,2x)* the Four Ball Box and therefore refer to this trick as the Stacked variation. Terminology issues aside, the Four Ball Stacked Box is a fairly difficult pattern to learn due to an intense combination of speed and accuracy.

    To begin learning the Four Ball Stacked Box, start with one ball in each hand. Make a very high vertical throw from your dominant hand while simultaneously making a horizontal pass from your non-dominant hand to your dominant hand. As your dominant hand catches the passed ball you are going to throw that ball vertically at roughly the same height as you would if juggling the regular three ball Box pattern. This throw and the very high throw should ideally peak at the same time. After catching the lower ball in your dominant hand you are going to pass it back to your non-dominant hand, clearing space for your dominant hand to catch the very high ball.
    Practice this on both sides until the timing of all your throws is comfortable and consistent. To add in the third ball start with one ball in your dominant hand and two balls in your non-dominant hand. Make the same high vertical throw and horizontal pass combination that you did in step one and then make the lower throw underneath it, except this time you will also make a simultaneous horizontal pass from your non-dominant hand to your dominant hand. If you were to freeze time you should see all three balls on the dominant side of your body—one very high, one lower, and one in your hand. As the lower throw descends you will pass the ball in your dominant hand back to your non-dominant hand and then also pass the lower ball back to your non-dominant hand to clear space for your dominant hand to catch the very high ball.
    Practice this on both sides. When you become comfortable enough with performing one cycle you will then want to combine the cycles on each side of your body. As you prepare to pass the second ball to your non-dominant hand at the end of the cycle you will instead pair that pass with a very high vertical throw from your non-dominant hand, thereby setting you up to repeat the cycle on the other side of your body.
    Though the sequence of throws is somewhat different than those of the Four Ball Stacked Box, this three ball exercise is still very helpful. To add in the fourth ball, start with two balls in each hand. Make a very high vertical throw from your dominant hand and then follow it up with a lower throw from your dominant hand and a horizontal pass from your non-dominant hand. As the lower ball descends you are going to make a very high throw from your non-dominant hand and a horizontal pass from your dominant hand, followed by a lower throw from your non-dominant hand and a second pass from your dominant hand. You will then pass back the ball in your non-dominant hand and catch both the very high throw and the lower throw in your non-dominant hand.
    And that's pretty much all there is to it. To continue the pattern simply make another very high vertical throw from your dominant hand along with the last horizontal pass and the rest of the throws will fall into place. The Four Ball Stacked Box requires quick and precise throws, a combination that will likely take you a fair bit of time to master.
