Q) Is the network safe/Is my machine safe on this network?

Have one machine for the game network, and one machine per contestant for monitoring traffic.
Have multiple network cards - One with a static IP for the game network, one in promiscuous mode for sniffing traffic.

However, there are events where we host only one round with the winner of that round being the overall winner. For Defcon round winners get advanced to the finals.
