Challenge tournament

This style of tournament is probably the easiest to run. You get all your fighters together, one fighter challenges another fighter, they fight, the loser goes to the list keeper to tell them who their opponent was (so the list keeper records the wins/losses for each fighter). This means fighters can fight as much as they like and more fights can be carried out at one time, although it also means that the hit list might become a little disproportioned. If one fighter only fights twice but wins both times, they have a 100% winning average, yet someone who has fought twelve bouts but lost four of them will only have a 66.66% winning average.
