Really Bad Chess is just like chess, but with totally random pieces. Try 8 Knights, 4 Bishops, and 3 pawns — why not? Whether you play chess daily, or quit just after learning the rules, this small twist will open the door to an entire new world of chess. Compete vs. an AI in Ranked, Daily, or Weekly Challenges. Improve your skills using the included Freeplay mode. Compete against your friends locally in versus mode! Warm up every day with our new daily chess puzzle — Knight Hike! ------A WORD FROM THE DEVELOPER Chess is one of those games I always wished I enjoyed, but its commitment to beauty, elegance, and perfect balance always turned me away. Really Bad Chess removes these boring restrictions and flips chess on its head. As much as random pieces change the game in some ways, I was really surprised to notice how much the game remains the same, and how powerful some pieces are — you've never truly struggled against a pawn until you've struggled against a pawn in the back row. For chess pros, Really Bad Chess will give you a new type of challenge — the pieces & the moves are the same, but you'll have to throw out your openings and your understanding of normal patterns of play. For novice chess players (like most of us), Really Bad Chess greatly opens up the game. Instead of starting by studying openings, in your first games you'll get to discover the joy (and challenge!) of learning how to checkmate. -zach
