When will the fun chess variants be available on mobile?

I really enjoy playing all of the many cool and interesting chess variants on PC, but I typically would rather play other games when I have free time. It would be really great if they were available on mobile so my friends and I could play all the time without needing to plan around schedules or choose chess over other more appealing options for entertainment. Don't get me wrong, Chess and its many variants are all fun and enjoyable and I'd love to play them all the time, but other games tend to draw my attention when I'm relaxing at home. I'd play the chess variants way more often if they were available on mobile since I religiously check in on the app to take my turns in regular games. Does anyone know if any variants will be added for mobile and if so, when could we expect to see betas for them? I'm not sure how hard it'd be to implement them to the mobile app considering all of the code should be done given how long the variants have been available on PC. But maybe the mobile platforms require different code to function properly? I don't know, I'm not a computer science major. Please let me know of any info regarding this topic as I'm very interested in seeing the variants on mobile.

I'm the same here, I'm pretty sure that the code would be different bc some of the variants have a really big board, so variants like that wouldn't work. But I think the ones that are needed for achievements should be added.

I don't know if there are plans to add any variants. The variants code is completely different and my understanding is that all variants, other than 960, are only going to be on the variants server in the future.
