Demonic Mahjong DLC “Heatwave Carnival” Test Live — 20% Off Soon!

If you’d like to join the test branch, right-click Demonic Mahjong in your Steam Library, select “Properties” → “Betas” → “testbranch,” then wait for the game to finish updating.

In addition to the 6 upcoming new characters—Dragonvine, Sweetie, Monotropa, Lycoris, Mandra, and King Dushi—this test version also adds 42 Figurines, 18 Relics, 2 Treasure Tile Spirits, and 15 brand-new Patterns.

As the new DLC is still in development, some character models, animations, voice lines, and other content may have missing art assets or temporary placeholder assets. Thank you for your understanding.

If you run into any issues during the test, please go to [Settings] → [Report a Bug] in-game and submit the details so we can investigate and fix them. Thank you for your support!

Regarding two questions many of you have been asking:

1. After the DLC is officially released, it will be optional content. There will be an in-game toggle, so you can choose whether to enable the new DLC based on your preference.

2. This update will not add any additional Steam achievements, but related achievements will be added in-game.

We expect the official version of the new DLC to meet you very soon!

Demonic Mahjong will reach a new historical-low 20% off discount on June 17! This discount will last until the end of the Steam Summer Sale on July 10!

In addition, our studio’s other game, Murders on the Yangtze River, is also currently at a new historical-low 40% off discount. Starting June 17, if you purchase the bundle containing both games, you can enjoy an extra 10% off on top of both games’ historical-low discounts!
