Triples (and Quadruples)

Triples is a card game where you try to spot triples of cards as quickly as possible.

Play it live at triples.vllmrt.net or via Telegram @TriplesBot.

The frontend is built using Elm and SVG. It should work both on mobile and desktop. Single player works fully client-side.

There is a Go backend included that supports multiplayer games and the Telegram integration.

Game rules

Every card has four properties: color, count, shape, filling.

Three cards form a triple if, for each property by itself, all three cards are the same or all three cards are different. (If this seems confusing, just try hitting the hint button at the top right.)

In the game, keep collecting triples, and more cards will be dealt automatically. It's possible that there are no triples to be found, in which case you can ask for extra cards using the button at the top right. If you missed a triple, this button will reveal the number of triples instead, and offer hints afterwards.

If this gets boring, you can move on to quadruples. For those games, four cards ABCD form a quadruple if there exists a fifth card X such that ABX and CDX are triples.

Deploying

Here's an nginx config fragment to make things work for the backend.

    proxy_pass http://127.0.0.1:8080/api/join;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";

    # go websocket origin check

}
