What it does
DarkSquares helps you master blindfold chess through a progressive training system. Start with fundamentals like square colors and coordinates, then advance to knight paths, tactical puzzles, and replaying famous games (Morphy, Kasparov, Carlsen) entirely in your head. The app gradually removes visual cues — from full board to silhouettes to complete blindfold. Play against AI at multiple difficulty levels without ever seeing the pieces. Available on web, iOS, and Android.
Free blindfold chess training app. 7 progressive levels from square recognition to full blindfold games. Web, iOS, Android.

We built ChessBoss at the TechCrunch Disrupt hackathon this week. It didn’t make the top 10 but I thought Hacker News might think it’s pretty cool. https://devpost.com/software/chess-boss There are these really cool smart chessboards that can suggest moves and track your games... but they’re $400 and weigh 19 pounds. And of course there are apps that can analyze games but tracking and inputting games by hand is a huge pain. Or fully-digital chess apps... but board games are way more fun in real life!

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986.
