# Rock-Paper-Scissors-Kata Kata for practicing OO style programming The inspiration for this Kata comes from an example in the book [Object Design: Roles, Responsibilities, and Collaborations](https://www.amazon.co.uk/Object-Design-Responsibilities-Collaborations-Addison-Wesley/dp/0201379430) and the rules in the [Object Calisthenics](https://www.cs.helsinki.fi/u/luontola/tdd-2009/ext/ObjectCalisthenics.pdf) paper by Jeff Bay. ## Description >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 throw the same shape, the game is tied and is usually immediately replayed to break the tie. > --[Wikipedia](https://en.wikipedia.org/wiki/Rock-paper-scissors) ## Kata Rules ### Stage 1 Write code to determine whether one shape object beats another. e.g. aPaper.beats(aRock) Do this for all combinations > rock crushes scissors > paper covers rock > scissors cut paper ### Stage 2 Refactor your code to adhere to these rules: * One level of indentation per method * One dot per line * Don’t use if, else or case statements ### Stage 3 Add Spock and Lizard to the equation: > Spock smashes scissors and vaporizes rock > Spock is poisoned by lizard and disproven by paper > Lizard poisons Spock and eats paper > Lizard is crushed by rock and decapitated by scissors ### Stage 4 Create a Game object that will simulate 2 players throwing shapes until one player wins the best of 7. Each round must be printed showing the shapes thrown by both players, the result of the round and a running total of the scores.
