Rock Scissor Paper Lizard Spock simulator

Rock Scissors Paper Lizard Spock

Create a system that can simulate a rock scissors paper lizard spock (RSPLS) tournament.

Rules of the Game

A game will start, and both player will select either Rock, Scissors, Paper, Lizard or Spock.

The rules for determining the winner are as follows:

• Scissors cuts Paper
• Paper covers Rock
• Rock crushes Lizard
• Lizard poisons Spock
• Spock smashes Scissors
• Scissors decapitates Lizard
• Lizard eats Paper
• Paper disproves Spock
• Spock vaporizes Rock
• Rock crushes Scissors

Basic Mode

Write a program that:

• Take a list of player names
• Simulates games of LPSLS between the all players (everyone plays everyone)
• Each match consists of best of 5 (configurable) games between each player
• Determines the winner based on number of match wins, and then game wins

Example - Start Options:

$ ./rpsls --players holsee, zulu, oscar --best-of 5

Example - Verbose logging output:

Game: holsee v zulu, holsee picked rock, zulu picked lizard, rock crushes lizard
Match: holsee 1 - 0 zulu

Game: holsee v zulu, holsee picked rock, zulu picked spock, spock vaporizes rock
Match: holsee 1 - 1 zulu

Game: holsee v zulu, holsee picked rock, zulu picked lizard, rock crushes lizard
Match: holsee 2 - 1 zulu

Game: holsee v zulu, holsee picked rock, zulu picked lizard, rock crushes lizard
Match: holsee 3 - 1 zulu, holsee wins the match!

Example - Results table:

| player | match wins | game wins |
| ------ | ---------- | --------- |
| holsee |  2         |  6        |
| zulu   |  1         |  4        |
| ada    |  1         |  3        |

Strategies

Design your player bot so that it can implement different strategies, and adapt based on opponents historical selections.

Distributed RSPLS!

Extract the game coordination logic into a server component that can coordinate remote actors as players within a tournament.

This should allow any player bot, written in any language to play each other in a tournament.

E.g.

[Server] Game Coordinator:

• broadcast new tournament
• schedule games
• start game
• compute winner
• store results
• broadcast results

[Client] Player Bot:

• listen for new tournament
• register in tournament
• listen for game start
• provide selection (RPSLS)
• obtain result
• listen for tournament results
