I had the concept in my head for some time and firstly just prototyped it using only HTML & CSS. Sent it to a few friends and they liked it so I made it into its own website and added few 'competitive' features like click counter and share button.

Hi HN! I'm the developer of rdx, a mildly popular ad-free, privacy and user friendly Reddit client. This time, I made something for a very specific use case: solving chess puzzles with no internet. Why? Well, my Wi-Fi is terrible in the bathroom—and that's where I do some of my best thinking. I tried printing out “mate in X” puzzles to solve offline, but they weren’t fun without interaction.

I like small puzzle games to play on my mobile, (because you can put them away easily as well). But I got really annoyed that a lot of them force feed you advertisements. To counter this I made my own puzzle game, as a progressive web app. This means you can install it on your mobile or desktop as an application, and play offline. After the game is offline ready, no requests should be outgoing except checking for updates of the game. So there is no tracking/reporting going on.
