--EDIT--
Changed playfield to better suit how the items move when water hits them.
It seems I had trouble passing from 1 row to another. Now it should be alittle easier.

Saw one made by sethbling, and thought it would be a cool idea to make one on my server. I did make several changes adding more features that makes my version far superior to sethblings.

I built this completely by myself from scratch.

Differences:
1. Mine has a pretty Redstone Lamp Display compared to sethblings sand display.
2. When you score 10 points you get a victory tune.
3. The ball is Auto-served for players. Who ever lost will have the ball served on their side.
4. The balls will stop being served after someone gets 10 points.

Basically the only thing in common is the play field which was a pain to replicate as I had to use the video as there were no screen shots and count out the spacings.

Give it a try with a friend!
Diamonds would be nice!

Additional Notes

Had to put it as a zip file as it wouldnt let me post it as is... (schematic file)

Please download and give feedback!

Btw due to my forgetfulness the dispensers MAY not have any Magma Creams (Balls) in them as my server uses a Supply Sign plugin.
So if need be, just fill both dispensers with magma creams or snowballs or whatever item.
