Proper term for "four way duel"

On this Wednesday's Survivor, Jeff Probst called one of the challenges as a "four way duel."

Now, obviously, this is wrong because a duel is between two opponents, but is there a term referring to a fight between four opponents?


Solution 1:

It would probably be best to say "a four-way contest".

Solution 2:

Why, it's a squirmish of course!
