## Overview

This Rails app serves a browser-based Rock–Paper–Scissors game. A player opens the game, chooses rock, scissors, or paper, and the show action generates a computer choice, determines the winner or a draw, and renders the result. The rules and random choice are implemented directly in the controller; no persistence layer is indicated. The view files are present in the tree, but their contents were not sampled, so their detailed form and rendering behavior is inferred from the README and filenames.

Main entry points: [`app/controllers/games_controller.rb`](https://github.com/karinatiurina/rock_paper_scissors/blob/master/app/controllers/games_controller.rb) (Games controller), [`config/routes.rb`](https://github.com/karinatiurina/rock_paper_scissors/blob/master/config/routes.rb) (Game routes), [`app/views/games/new.html.erb`](https://github.com/karinatiurina/rock_paper_scissors/blob/master/app/views/games/new.html.erb) (New game view), [`app/views/games/show.html.erb`](https://github.com/karinatiurina/rock_paper_scissors/blob/master/app/views/games/show.html.erb) (Round result view)
