Think you're good at puzzles? You've never experienced a fast action puzzler like this before! Crystal Clash competitively pits you against other online players around the world in realtime, requiring quick puzzle solving skills and fast reactions in order to win. In the world of Crystal Clash, you are the lord of your castle, and your soldiers, called "Bits", assist you in expanding your territory. Both you and your opponent simultaneously solve the same set of pixel logic puzzles, and with each correct fill, your Bits automatically advance and attack your opponent. Decide the best strategy for your Bits by controlling the lanes they attack on -- either keeping your defense strong, or pushing them all for a full attack to claim your opponent's area. For each puzzle you solve, you'll gain experience to level up your Bits, increasing their strength, defense, speed and hit points, and will unlock new and powerful skills for use in battle!


Crystal Clash was developed in a span of three months, and simultaneously released and exhibited at Tokyo Game Show 2017 in the Indie Games Area, booth 9-B43. Crystal Clash uses Cold Fusion's in-house developed high performance multithreaded 3D rendering engine and multiplayer networking technology. Updates are continually released every two to three weeks, adding new features and functionality to the game.


  • Hyper-speed puzzle battles!
  • Fight against other players from around the world in realtime!
  • Gain experience, level up, and build and customize your own character!
