I'VE RIGGED THE PLACE TO BLOW... OR HAVE I?: At the beginning of the game, you may place up to 6 Bomb special markers as described on this card on the map, at lease 4 squares from any starting area and each other.

Can I place the Bombs in the boxing ring?

What makes you think this would not work?

2nd player gets to place special terrain before placing objects. These are placed after objects.
