Extending the game

The natural extension of this game would probably be Rock-paper-scissors-lizard-Spock. This can be achieved by simply extending the constraint object in the RockPaperScissors class.

Here's a quick example for lizard

this.constraints = {
	rock: {
		name: 'Rock',
		beats: {
			scissors: 'crushes', // rock crushes scissors
			lizard: 'crushes' // rock crushes lizard
		}
	},
	scissors: {
		name: 'Scissors',
		beats: {
			paper: 'cut', // scissors cut paper
			lizard: 'decapitates' // scissors decapitate lizard
		}
	},
	paper: {
		name: 'Paper',
		beats: {
			rock: 'covers' // paper covers rock
		}
	},
	lizard: {
		name: 'Lizard',
		beats: {
			paper: 'eats' // lizard eats paper
		}
	},
};
