Then they keep trying for the next 5 days right it didnt seem like there was a match limit between the assassins and the targets it's just you have to stay alive if your the target for 5 days basically meaning you cant lose to the assassin at all during the 5 days

Than after those 5 days are up if the Target survived and met the parameters set originally on games played and such than he would be moved on and get the round prize.
If the Assassin wins a single match in those 5 days he moves on and gets the round prize.

That's basically how I understand it working from how the rules are setup.
