Ask HN: What are you working on?

I've spent several last years solo-developing an ad-free website with over 50 different solitaire/puzzle games (https://inSolitaire.com). I've rewritten this project (almost) completely four times and tried my very best to make it work on both desktop and mobiles.

I would be incredibly grateful for any feedback – I'm looking to genuinely improve the experience. Specifically, I'm wondering whether it is easy to use and what it lacks.

I have a huge backlog to cover for this, but so far it has been great fun and I have learnt an incredible range of things!

In Klondike, not being able to drag out a card from the ordered pile + the app automatically moving cards there is seriously limiting. The odd thing is that you can manually undo automatic moves, but you need to press "undo" to every move because they will be re-played the next turn. Additionally, the auto-moves are buggy and they don't always work at the very end, where they probably make more sense.
