The application can be launched with:

petanque::runShinyApp()

The aim of the game is, as in a usual game of Pétanque, to land your balls as close as possible to the target ball (red). Each player has 3 balls to throw, and players alternate throws.

The game is controlled with the keyboard as described at the bottom of the page.
