Short games are oNen played among friends to quickly determine who should $$go first$$ or for a

winner to resolve some other dispute. It is ideal to have a game that can be played quickly and

available for mobile cell phone devices. This is where a game like $$Rock$-$Paper$-$Scissors$$ comes

in$!$

Workshop Details

A complete descripCon of the human$-$to$-$human set of rules for the $$Rock$-$Paper$-$Scissors$$ game

are available here: hXps:$//$ m$.$wikihow.com$/$Play$-$Rock,$-$Paper,$-$Scissors. However, the main

concepts will be provided in this document as well.

A soNware developer wants to create a version of this game for SMART mobile phones,

however before considering the soNware approach, a thorough understanding of the game in

its physical format is required. The rules for this game are very simple:

Game Rules and Requirements

$$ Two players are needed $($Human vs$.$ Computer$)$

$$ A start rouCne is required to help build suspense and Cme for the human player to choose

their desired object $($usually a countdown of three$).$ The animaCon will involve moving two

fists up and down synchronously.

$$ There are only three $(3)$ possible plays $($objects$)$:

$1.$ Rock: Represented by a hand making a "fist" shape

$2.$ Paper: Represented by a straight open flat hand

$3.$ Scissors: Represented by spreading the index and

$2$nd finger apart $($mocking scissors$)$

$$ Each object type can be defeated but can also be a winner depending on the opponents

chosen object.
