The true box is a variation of the 3 ball box where one ball follows a rectangular path around the outside of the pattern. The siteswap for this pattern is the same as the normal box - (4,2x)* - but the 2x ball is thrown four different ways:
- The ball is thrown horizontally across the bottom of the pattern.
- The ball is thrown upward and caught at the top of the pattern.
- The ball is thrown horizontally across the top of the pattern. The right hand catches and throws the ball while reaching across to the left side of the pattern and vice versa.
- The ball is dropped back down and caught at the bottom of the pattern.
