Hello everyone! Thank you for your interest and support in the roguelike mahjong game Demonic Mahjong!
Back in April, we nervously released our first demo—a version riddled with bugs, featuring only a handful of playable characters and limited strategies. We’re incredibly grateful to all the players who helped us test repeatedly, uncovering many bugs and providing invaluable optimization suggestions!
Over the past two months, through over a dozen major updates—each introducing nearly 100 changes—we’ve gradually expanded the game’s content while squashing more and more bugs.
Playable characters have increased from the initial 6 to 21;

With the addition of talents, progression systems, and more figurines, offerings, and relics, the game’s playstyles and strategic depth have grown significantly;

More visual effects and animations have further elevated the battle experience:

During the recent Steam Next Fest, nearly 10,000 mahjong enthusiasts braved the underworld to play the demo, with the average playtime exceeding 7 hours—and many players even surpassing 100 hours!
After continuous polishing, we’ve decided that the full version will officially launch on July 16! The price will be $16.99 with a 10% discount for the first two weeks!

We’re still working hard in these final two weeks to ensure the full version delivers a more complete experience!
Here’s what you can expect in the official release:
Full voice acting—breathing life into the underworld’s "ghosts"!
Immersive story integration—unravel the tale behind Demonic Mahjong.
More new characters, figurines, and relics—expand your strategic options.
Final secret stage—a "Hell Heart" challenge awaits the most skilled players! (Coming within two weeks of launch.)
Revamped tutorial—easy to learn, even if you’ve never played mahjong.
Major balance adjustments, bug fixes, and UI optimizations—for smoother gameplay.
But this isn’t the end! Post-launch, we’ll continue updating with plans including:
Expanded lore—new themed stages and characters (e.g., Greek Hades).
Additional mahjong variants—more diverse battle modes.
Character stories & affinity system—deepen bonds with the underworld’s "ghosts."
Multilingual voiceovers—Japanese and English dubs are in the works.
Better controller support—more seamless controls (currently playable via touch on Steam Deck).
