wizard_game

Pure-Python rules engine of Wizard (no dependencies). It is used by the game server and can be installed on its own to train AI players:

pip install ./wizard_server/game_logic

import random
from wizard_game import WizardGame, GameOptions

game = WizardGame(num_players=4, options=GameOptions(not_equal=True), seed=1)
rng = random.Random(1)
while not game.is_finished:
    player = game.current_player
    obs = game.observation(player)          # what this player may see
    action = rng.choice(obs.legal_actions)  # Bid / PlayCard / ChooseTrump
    events = game.apply(player, action)     # TrickCompleted, RoundCompleted, ...
print(game.scores, game.winners())

Observation.to_dict() / Observation.from_dict() and action_to_dict() / action_from_dict() define the JSON format that the server sends to web clients and to the AI service.
