This is not something for the near future, but an idea that I'm toying with for 2025. I'm really working to better engage our community, and we seem to have a ton of developers!
As some users know, about twice a year I do a stamp card rally on the dashboard, where you have simple little games/activities that you can play for a daily stamp and a reward at the end of the month.
A lot of people have asked to have that more often (or even put the games somewhere in a permanent spot), but I've always felt bad because, at the moment, there are 3 minigames, and so each one has to run for 10 days (1/3 of the event period).
All of them are written using html/js (no frameworks, jquery is the only library that I have), no api calls (the data (vocab, or whatever) is preloaded, and are effectively encapsulated into a single block of code. The only real interaction with renshuu the server is the initial generation of data (say list of words, or whatever), and then the final "they're done, this is how many points they got" update.
I'm wondering if frontend developers would be interested in a contest to make these little minigames for renshuu, so our stamp-rallies could be more frequent and/or more varied.
If you're curious, here are the three games we currently run:
1. Drawing challenge - given a prompt "like draw a どうぶつ", then you can draw one. Just a way for simple interaction with words.
2. character scramble - get a grid of characters, then try and make as many words as you can in the time period
3. speed matching - I believe it's a single definition, then two words. You have to tap one or the other, and it gets really fast really quickly.
I still have the code laying around for a picture based one, but I cannot recall why I stopped using that.
Anyway, I'm curious as to if there'd be interest in this! renshuu's backend is not clean enough to open up a free area for people to develop games to work off of renshuu's api, but this might be a good step in that direction.
