Game play and sounds effect:
How you choice to play the game is to press pick one of the three hand-signs display on the upper top screen against a computer simulated games.

Each of the three basic hand-signs (from left to right: rock, paper, and scissors) beats one of the other two, and loses to the other against computer watch.
The players pick one of the hand picture and count aloud to 3, or speak the name of the game (e.g. "Rock Paper Scissors!" or "Ro Sham Bo!")

Process:
Hand-sign is generate randomly by computer

var randomNumber = Int(arc4random_uniform(3))
if (randomNumber == rock or userChoice == paper) and or
(randomNumber == paper or userChoice == scissors) and or
(randomNumber == scissors or userChoice == rock)

"You Win!"

else if ( userChoice == rock or randomNumber == paper) ||
( userChoice == paper or randomNumber == scissors ) ||
( userChoice == scissors or randomNumber == rock) {

"Computer Watch Win!"

else "It's a Draw".

Other names for the game in the English-speaking world include roshambo, ick-ack-ock, ching-chang-walla (in some parts of South East England), and other orderings of the three items, sometimes with "rock" being called "stone".
