500 - Multiplayer card game

500 is the classic trick-taking card game of Australia and New Zealand. Outbid the other side, call trumps, and steer your partnership to 500 points — with the Joker, both bowers, and the ever-tempting Misère along the way. New to 500? The interactive tutorial deals you a real hand and coaches you through every bid, discard and trick — the fastest way to learn the game that keeps families arguing (fondly) for generations. Features: * Full Australian rules: a 43-card deck with the Joker, both bowers, a 3-card kitty, bidding from 6 to 10 tricks across the suits and no-trumps, plus Misère and Open Misère. * Play offline against capable AI opponents — no account, no network required. * Play online with friends: create or join a room with a short code, with cross-play between Android and the web. Any empty seats fill with bots, and if someone drops out a bot plays their hand until they rejoin. No account needed, and you can point the app at your own server. * Four ways to play: the classic 4-player partnership game, 2-player head-to-head, or 6 players as two teams of three or three teams of two. * Interactive tutorial that teaches by playing, not by reading. * House rules: switch Misère or no-trumps bidding off to match how your table plays. * Learn to count cards: hold each finished trick on the table for as long as you like, and slow down or speed up the pace to taste. * A proper score sheet: every hand's contract and points, tallied at game end. * First side to 500 points wins. This app is free and open source. Source code at https://github.com/rotundtapir/500
