I'm still working on it. I think there are a few bugs so only a world file for right now.

once you decide who goes first, press start, and shoot your target. When you hit a button wait to see if the light goes on. And then wait for your turn. The light up top will tel you when its your turn. If no light comes on wait. it is slow, and there is nothing I can do about it, I dont think. There is also a single player mode. Just pull the lever

When your done press stop and all the lights will go on, reset, then turn off. Any questions just ask in the ocmments below. I will try my best to help.

Just remember, there is alot of redstone wiring, and that means alot of repeaters. so it is slow, give it some time

Additional Notes

The first person to get all 12 buttons wins

Take note, most of the instructions I have put above will and may change untill I feel I have completed the project.

Schematic will not be updated for a while untill im completely done. due to the new update.
(I can not Greentree this works remotely. It has been a good long while since i built this and I hardly touch minecraft. that being said, if some one wants to take this and fix it up with more current methodology of redstone, then by all means do so.)
