About Roshamboss
Powerful monsters have appeared in Hybris. The fate of the city rests in the hands of its Heroes. Roshamboss is a strategy card game for 4 friends. In this 1v3 card game, 1 Boss fights 3 Heroes in Rock Paper Scissors with superpowers. We recommend playing with friends in voice chat.Roshamboss is a party game for strategy players. Each round, the Boss places a Rock, Paper, or Scissors "throw" face down, then the Heroes take their turn together.Damage is dealt based on the results until only one team remains.Here it is step-by-step:The Heroes respond together: each Hero chooses their own throw. Every comp enables new strategies—work together and lock in! The Dare phase: after the Heroes lock in, the Boss has a choice: single out a Hero and dare them to change their choice, or start combat. The Reveal phase: Combat begins when the Boss flips their card and damage is dealt based on the results. Do it again, but bigger: Strengthen your throw to deal more damage, apply Tiebreak to win on ties, Protect yourself or allies from harm, or Armor up to tank it all.
