Ask HN: Those with money-making side projects,how did you come up with the idea?
I've created an online solitaire platform (<a href="https://online-solitaire.com/" rel="nofollow">https://online-solitaire.com/</a>) that's earning me $10k/m now. It started as a side-project 5 years ago, but I've recently gone full time on it.<p>It actually started as a Mac app 10 years ago and I choose to create a solitaire game because I had made a string of side-project that I didn't earn any money on, so I wanted to see if I could find a project that would actually generate some side-income.<p>I did it by scraping the Mac App Store so I could find apps that had a lot of downloads and bad reviews. I figured that if an app had a lot of downloads, but got bad reviews then I could create something better and there would be an audience for it. The app ended up making enough money that I've kept it as a side-hustle for all these years. I've written about how I picked the app here: <a href="https://www.indiehackers.com/post/how-i-grew-a-simple-solitaire-game-to-10k-mrr-28e352c308" rel="nofollow">https://www.indiehackers.com/post/how-i-grew-a-simple-solita...</a>.
