### Quick Start



- To run the single game application, use the following command: `./gradlew run`



- If you don't have Java 23 installed on your system you can install it first with [SDKMAN](https://sdkman.io/):



```bash

curl -s "https://get.sdkman.io" | bash



sdk install java 23-tem



./gradlew run

```
