There are three versions of BoxxyBall: Standard, Pro and Youth.
The net for BoxxyBall Standard and BoxxyBall Pro is 8 1/2 ft tall.
The net for BoxxyBall Youth is 7 1/2 ft tall.
BoxxyBall Standard and BoxxyBall Pro can be lowered to 7 1/2 ft by switching the regular B poles for the shorter BY poles. BoxxyBall Youth can be raised to 8 1/2 ft by switching the shorter BY poles for the regular B poles. (Pole A and Pole C are the same for all versions of the game)
You can purchase B poles and BY poles on the BoxxyBall website.
Tip 1: BoxxyBall Standard set-up with the shorter BY poles is identical to BoxxyBall Youth, just as BoxxyBall Youth set-up with the standard B poles is identical to BoxxyBall Standard.
Tip 2: BoxxyBall Pro is identical to BoxxyBall Standard, apart from the net – which is only two rows of ten boxes (the standard net is three rows of ten boxes). BoxxyBall Pro is identical to BoxxyBall Youth, apart from the net and the BY poles.
