Show HN: Play Riichi Mahjong Online

I'm presenting a website where you can play Riichi Mahjong (4p strategy and luck boardgame):

- Play Mahjong as a guest or registered user

- Invite other players or play against bots

- View your game history and publicly share it with others

- Use the hand calculator for scoring your offline games at https://online-riichi.com/score

The game client has been inspired by "online-go" which I really enjoyed playing on - it's simplistic but feels tactile and remains true to the "feel" of the game. I would like to achieve the same thing.

As part of preparing to share on HN and reading the posting guide, I've added a "Play as guest" button so you don't need an account to play.

Finally, my own selfish goal is to gather a small player base which I can develop features for. My question for HN is - how would you go about attracting users to this kind of project?

All is built with Postgres, Rust and Preact. Done as a pastime to work. I'm sharing it now because I promised myself to do so before the end of the year! I've added a discord link on the website, but you can also contact me at cerpinsmiks@gmail.com.

Merry Christmas!

What worries me about this is that the benefit of well practiced developers using AI to boost their productivity is there, but what happens to the new developers that piggyback off of LLM tooling too much and end up with worse understanding as a whole?

It sounds like it might be a good use case for testing documentation - verifying whether what documentation describes is actually in accordance with the code, and then you can act on it. With that in mind, it's also probably pointless to re-run if relevant code or documentation hasn't changed.

Working on a full on Riichi Mahjong web client because I really like the game and want to make a more serious english client without anime.

Did it also to learn rust, which made it easy to convert the engine code into webassembly and create a hand score calculator for the game :)! https://cerpins.com/mahjong-tool

Plans now are to finish the client, then freshen up the calculator with some QOL and visuals, surely a bug fix might be needed here and there as well.
