Kinda late for the party, but... In the coming several weekends I'm improving my passion project – ad-free website with solitaire/puzzle games (https://inSolitaire.com). I got some valuable feedback from niche subreddits.

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 grateful for any feedback as I'm looking to genuinely improve the experience. You can help me answering the questions "What does it lack?".

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