Blood Bowl Three Way Throwdown!

Nope, here it is, just about the closest 3x board you could do in hexes, I bet. 15 squares wide, and 13 squares to score a TD from the LOS.

One slight anomaly is that you can line up in the center front square, and an opponent can still get three guys to your right on the LOS, not in you TZ, and not in the wide zone.

Kick offs are done by rolling dice. High roll chooses to receive or kick. If he chooses to kick, 2nd highest makes the choice, then the third. The kicker with the highest roll sets up first, and will kick the ball to the receiver. The kicker with the lowest roll then sets up, but is not considered to be the kicking or receiving team (although any KO results which affects both the kicker and receiver affects him similarly-- Throw A Rock affects the lowest roll). Finally, the receiver sets up last and takes the first turn as normal.
A block is only between players on the teams of the blocker and the target; and TZs from the third team are ignored. Fouls are similar. All TZs count for dodging. Any team member can intercept.
I still think it might be a good idea to narrow the center of the fields to 5 squares wide, and play 9 players per team.
