Under the hood
  • Written in Java with libGDX. The same code runs on Android, Windows, macOS, Linux and the web, where TeaVM compiles it to WebAssembly.
  • It started as a console game in the terminal, to test the mechanics before there was anything to look at. The console version is still there, and it's where the bot runs.
  • Scoundrel is mostly luck, and it's hard: plenty of deals are close to impossible to win. Playing a few games can't tell you whether a rule change makes it easier or harder, so a bot plays 50,000 runs with each of the eight challenge modifiers, and their score multipliers come from those results.
  • A card theme is just a folder with a JSON file and its icons, so making one takes no coding at all. New themes are welcome on GitHub.
About the game

Scoundrel is a one-player card game by Zach Gage and Kurt Bieg, played with a regular deck of cards. Deckdelve sticks to the official rules by default. The extras, like the challenge modifiers and the rule variants, are all optional.

There are no ads, no accounts and no tracking. The game never goes online, and the Android version doesn't even ask for the internet permission.
