Rock Paper Scissors played against everyone at the table at the same time. You are not facing one opponent, you make a single pick against every player in the room, and your score is the net result of all those matchups. That small change turns the game into something quite different from the two-player version.
You get 10 seconds when the round starts. Pick Rock, Paper or Scissors. Your choice locks and the game waits for the others; if everyone locks early the remaining time is skipped and the result opens immediately. Miss the deadline and you take 0 for the round.
The result screen shows what everyone picked, so you can read who leans where before the next round. Play a few rounds with the same group and it turns into a bluffing game.
The formula is simple: players you beat minus players who beat you. Anyone who picked the same thing as you does not count. Your score can go negative; at a table of six, beating two people and losing to four closes the round at -2.
So the real question is not "what will my opponent pick" but "what will the majority pick". If half the table plays Rock, Paper takes the round on its own.
At a table of three the game still resembles the two-player version: reading one person is enough. Past six players reading individuals becomes impossible and the game turns statistical; you are estimating what share of the table plays Rock. The score range widens too: at a table of eight a round can land anywhere between +7 and -7, so a single correct read can swing the whole match.
In solo mode three bots fill the table, so you can try the game on your own. Two of them follow a round-to-round pattern and the third picks at random; crack the pattern and you can close most rounds in the black. Bots lock before they can see your pick, so nobody is peeking.
For the real thing still open a room and bring friends. Human bluffing is messier than any bot can imitate, and the bigger the table the better the game gets.
