## Overview

This is a web casino application with account registration/login, user and admin pages, and browser-playable roulette, slot, and crash games. The visible game workflow is player interaction → game logic and result display; one slot client also fetches and submits balance updates. The tree identifies backend controller, service, model, and repository layers, but their source was not sampled, so backend calls beyond the explicit slot HTTP requests are left unwired. The duplicated resource trees are represented only where sampled behavior supports them.

Main entry points: [`src/main/resources/templates`](https://github.com/yaroslav-kirsenko/casino/tree/master/src/main/resources/templates) (Pages and entry), [`src/main/java/com/example/Casino/Controller/AuthController.java`](https://github.com/yaroslav-kirsenko/casino/blob/master/src/main/java/com/example/Casino/Controller/AuthController.java) (Authentication routes), [`src/main/java/com/example/Casino/Repo`](https://github.com/yaroslav-kirsenko/casino/tree/master/src/main/java/com/example/Casino/Repo) (User repositories), [`src/main/resources/templates/LoginRegister`](https://github.com/yaroslav-kirsenko/casino/tree/master/src/main/resources/templates/LoginRegister) (Login and register)
