It is known that Rock Paper Scissors (RPS) is already mentioned in 15th Century Chinese resources. So the origins of the game may be dating back even earlier. The modern version of RPS
becomes widespread in Japan in 18th Century, and has been popular throughout the world since the 20th. Today there are quite a number of national and international RMS tournaments around the
RSM is usually played between two people.
Each player simultaneously forms one of three shapes with an outstretched hand. These shapes are "rock" (✊ a simple fist), "paper" (✋ a flat hand), and "scissors" (✌️ a fist with the index
and middle fingers together forming a V).
The game has only three possible outcomes other than a tie: a player who decides to play rock will beat another player who has chosen scissors ("rock crushes scissors") but will lose to one
who has played paper ("paper covers rock"); a play of paper will lose to a play of scissors ("scissors cut paper"). If both players choose the same shape, the game is tied and is usually
immediately replayed to break the tie.
At the end of each clash, the loser is punished with a humble display of violence - the loser holds his/her playing hand extended, and the winner (using the two scissors fingers closed),
hits a stroke on the outer part of the hand at a point close to the wrist.
Beware; as the game proceeds, the redness of the hands, pain, and the power of strokes will probably increase.
