“George Washington is reputed to have played it with Cornwallis and the Comte de Rochambeau to decide who would be the last to leave Cornwallis’s tent after the signing of the British surrender at Yorktown in 1781. (The story goes that Rochambeau won, which is why the game is still called Ro-Sham-Bo in some quarters.)”

Rock, Paper, Scissors is a real game played in Regular Show by Mordecai and Rigby. Benson says it’s an evil game.

Rock, Paper, Scissors. The familiar game of Rock, Paper, Scissors is played like this: at the same time, two players display one of three symbols: a rock, paper, or scissors. A rock beats scissors, scissors beat paper by cutting it, and paper beats rock by covering it.

Upon making a decision the Emperor would have his servants place a sheaf of paper either over or under the rock. If the sheaf was placed under the rock it would signify acceptance of the petition. If the sheaf was placed on top of the rock it signified denial of the petition.

Paper covering a rock still makes sense in an object that is greater than another. This is why the paper beats the rock, just because it does not do any damage to the rock it still makes the rock invisible to the rest of the world rendering it useless.

“Rock is actually a mistaken piece of dog poop. So paper is the only thing that can pick it up and diapose of it. Poop beats scissor because well, No one wants to use dirty scissors.”

That last one is a particularly effective bar hustle, as a cheater can challenge someone to “rock, paper, scissors,” claim victory if they win the first throw, and then continue on as if they always intended to play a “best of whatever” if they lose the first throw until the odds are in their favor (which they …

Scissors shows you are calm. If you want to cut an object or open a box using scissors, you sure have to be careful with it to cut perfectly. Scissors shows you are cunning and waiting for an opportunity. If you thought you could suffocate Rock by throwing Paper, you have just prepared a sweet meal for Scissors.

Because scissors is the statistically least often thrown move, and because rock is the most often thrown move, paper is the best way to go. Paper will beat rock, which is the most commonly thrown move. Scissors can beat paper, but because it’s the least often thrown move the chances of losing are much less likely.

Therefore, this is the best way to win at rock-paper-scissors: if you lose the first round, switch to the thing that beats the thing your opponent just played. If you win, don’t keep playing the same thing, but instead switch to the thing that would beat the thing that you just played.

The best strategy for rock paper scissors is to truly act randomly. This means playing each option about one-third of the time, ensures an opponent can’t guess what’s next.

it turns out that the most common throw is rock (35 percent), scissors (35 percent), and then paper (29.6 percent).

In the game Rock, Paper, Scissors, two opponents randomly toss out hand gestures, and each one wins, loses or draws with equal probability. It’s supposed to be a game of pure luck, not skill — and indeed, if humans were able to be perfectly random, no one could gain an upper hand over anyone else.

Notice that playing rock is a dominant strategy for both players (i.e its best to choose rock, regardless of what your opponent is playing! Therefore, the equilibrium for this game is unique: Both players always select rock.

You have a 1 in 3 chance, each round, of getting a particular result (win, lose or tie).

1/3rd chance of it happening each time. It doesn’t matter what you draw, because the first person’s choice doesn’t matter the 2nd person has a 1/3rd chance of matching it. That does assume that all throws are independent, random and equally likely.

Each preliminary round will consist of a “best of three” head to head competition of each team member (3 head to head individual battles, best of three each). Each individual winner will score one point for his/her team. First team to win two points wins the match and advances to the next round.

A game of rock, paper, scissors. As long as it’s a draw, nothing bad will happen. As long as it’s a draw, nothing bad will happen. As long as it’s a draw, nothing will happen.

There’s a 1:3 chance that the other player will pick what you do. The problem is that 100 games isn’t enough to guarantee a 33% agreement.

If you always select rock, then you will still always have a 1/3 chance of winning. If you select only scissors or paper in any given game, you will still always have a 1/3 chance in each game.
