A blackjack game engine with optional no_std support.

Features

  • Full round flow: betting, player actions, insurance, dealer play, showdown
  • Configurable rules via GameOptions
  • Deterministic RNG seeded at game creation
  • std by default, no_std + alloc supported (enable alloc)

Usage

let options = GameOptions::default();
let game = Game::new(options, 42);

let player_id = game.join(1_000);
game.start_betting();
game.bet(player_id, 50).unwrap();
game.deal().unwrap();

// Player actions, dealer play, and showdown omitted here.
