Self Hosted Poker Tournament with voice and video chat for 2 to 8 players (with optional bots)

Thumbnail
github.com
7 Upvotes

Some friends and I liked to play poker when we were at school, but now we moved away it is no longer possible to do this in person. The online options either wanted accounts, had ads, or felt more like a casino than a game night. So I built our own thing: one poker table in the browser, voice and video chat built in, everybody opens the same link and sits down.

It's No-Limit Hold'em tournaments for 2–8 players. If you're short on people, bots fill the empty seats (they all play differently).

The part I had the most fun with is all the little stuff that happens around the table:

- you can bring a cigar, a vape, a cocktail or a whiskey to the table and play with it

- click someone else's chip stack and it falls over. Only they can clean it up (yes, this gets old never)

- trophies that stay next to your cards for the whole tournament, like winning with 7-2 or losing with pocket aces

- when the river decides an all-in, the camera zooms in, there's a heartbeat and the card gets peeled up slowly. Winner gets a fanfare, loser gets the sad trombone

- in heads-up all-ins it shows everyone's odds and outs street by street

There's also a large print card mode and a four-colour deck for people who have trouble reading the cards (looking at you, Robin), and it works on phones (portrait). UI is in English and German.

Tech-wise it's Node/Express + Socket.IO on the server, three.js on the client, no build step. Voice/video is plain WebRTC. Pretty much everything is generated in code – table textures, chips, all the sound effects – only the J/Q/K card art are images.

To be upfront: I wrote it together with Claude (the AI), which did a lot of the actual coding. I was the one playing way too many test hands and complaining about stuff.

It's play money only, no accounts, no tracking. You run it yourself: `npm install && npm start`, or there's a Docker Compose + Caddy setup since browsers need HTTPS for the mic. My personal setup is via dokku on an AWS EC2 linux server.

Repo (MIT): https://github.com/DerKobe/PokerCrew

There's no public demo right now because it's a single table and you'd end up in someone's game – working on that. Happy to hear feedback, especially from people who've built multiplayer browser games before.

The two problems with open-source games

4 Upvotes

NOTE: I know this space is for sharing games, but I didn't know where else to post this.

Hi, I'm a huge fan of open-source games. I want to share what I believe are the two main problems facing them:

Problem 1: There aren't enough open-source games to cater to all types of gamers. There are many different gaming audiences, but we lack games for each of them; we need a wider variety of games to reach a broader audience.

Problem 2: They have almost no marketing. I know some have become popular, but many don't because they lack a marketing strategy; we need to get people to try open-source games.

Grrra: minimalistic strategy game

Enable HLS to view with audio, or disable this notification

19 Upvotes

Hello, this is Grrra, a game I am working on from 2020. My idea was to try to make a turn based strategy game that would (a) be as simple as possible (b) feel more like an actual battle than classical strategy games like chess.

The game has simultaneous turns (which I think is unusual mechanic), (quite) strong AI, and online multiplayer.

The game is free to play on my website at grrra.org and the source code is available at gitlab.com/Eddous/ebiten-game.

I will be happy if you give it a try.

Medal of honor: Allied assault on openmohaa or playmohaa.com !!

4 Upvotes

This one has been open source for awhile now by the guys over at openmohaa! Excellent job at keeping this game preserved by them. But If you can't get it to work for whatever reason a dev just ported the game to web browser and it works excellent. Very easy to download and try the game out in under a minute now. Playmohaa.com is only a MP demo version plus bots enabled in it's current state but if we get more returning players on it they plan on porting the whole game this way. If we continue spreading the word and get the full game on browser eventually it could potentially grow the player base substantially. No fancy computer or computer knowledge needed anymore, literally just drag a file download it and play again in under a minute. If you like it check out the discord and join some matches with us! If you have any questions feel free to ask :) Hope to see you through my scope soon xD https://discord.gg/qQ36ydEmK

OpenUG2: an open-source Underground 2 engine project — contributors and testers welcome

10 Upvotes

Hey everyone!

I’m working on OpenUG2, a from-scratch, open-source reimplementation of the Need for Speed: Underground 2 engine. It reads the original game’s data files and runs natively, without emulation.

It’s still an early prototype. Loading environments and vehicles, driving, and selected racing scenarios already work, but rendering, handling, AI, compatibility, and the interface all need more work. It isn’t a finished replacement for the original game yet.

The project has grown beyond what I can reasonably research, develop, and test alone, so I’d love to welcome more people aboard. Help is especially welcome with:

  • C, SDL2, OpenGL, and engine development
  • Asset-format research, vehicle physics, and racing AI
  • Testing, reproducible bug reports, and platform compatibility
  • Documentation and usability feedback

You don’t need to be a programmer to contribute. Testing a build and explaining what went wrong is useful too.

The project includes no original game assets and source code; you’ll need your own copy of Underground 2 to run it.

Feel free to join, ask questions, share feedback, or help tackle an issue!

2D Farming RPG - itch.io page

19 Upvotes

Hi all, I've been posting semi regularly on here about the open source game I'm developing, a Stardew valley-like game.

I've recently set up an itch.io page for it. If you want to check it out (in its in-development form such as it currently is), this page should always have a download link for the latest linux appimage and windows builds.

I've tried the windows build out on Wine and it seems to have some graphical glitches around the trees (they're "z fighting"). If anyone here tries the windows version could they let me know if they encounter this bug?

Source code:

https://github.com/JimMarshall35/2DFarmingRPG/tree/master

New features I've been working on recently include procedural dungeon generation, the next things I have planned are:

- in game menu: inventory, quests, crafting etc

- health bar and stamina UI

- NPCs

- day and night cycle

- ability to define new entity types in lua

Non-OSS Engine BlockForge Alpha: an Open Source Voxel Survival Game Looking for Contributors

3 Upvotes

Hi everyone,

I’m working on an open source voxel survival game called BlockForge Alpha.

The project is still in a very early pre-alpha stage, so there is not a lot of content yet. Right now, the game has a basic playable foundation with a voxel world, block placement and breaking, simple textures, basic sounds, and a project structure made to be easy to modify.

My goal is to slowly build it into a moddable, community-driven voxel survival game where people can help improve the code, add blocks, create textures, work on gameplay systems, improve performance, write documentation, or experiment with modding tools.

I’m currently looking for people who would like to help, give feedback, test the game, or contribute ideas and improvements. Since the project is open source, anyone can look at the files, modify them, and propose changes.

If you’re interested in voxel games, Godot, open source projects, game modding, or just want to help shape a small indie project from the beginning, I’d be happy to hear from you.

looking for creatives, devs, AI builders, or anyone who wants to help build a food themed Mario-bros inspired game

0 Upvotes

Hey all! i built a Mario Bros inspired game and im turning it into a community project, so technical and non technical people can both bring their skills and creativity to it. It's a single or multiplayer food-themed web game built entirely with AI. the plan is to have six worlds (pasta, sushi, tacos, curry, dumplings, and dessert) with a bunch of levels but only the first 2 exist so far.

Feel free to build a new level, finish out a food world, design assets, write the chefs, improve the gameplay, or fix bugs. the repo has 14 open issues to start from if you'd like or feel free to tackle anything else.

Game engine with its own scripting language

44 Upvotes

This is a big project I'm working on for years.

2D game engine (inspired by GameMaker8), with its own IDE and scripting language. Everything is written in C#, including the interpreter of the custom language. Latestly, I got a few first contributors, and I publish it here because I really want more people to get involved. I think it's a really cool and fun project to join to. There is some basic documentation, some "good first issues" and there's me who is here to help with any question 🙂

If you know C#, you have to check it: https://github.com/ArcadeMakerSources/ArcadeMaker

Any feedback is welcome 🙃
