Augment Mahjong Demo

※ About the Demo Version

The current demo build focuses on verifying 'multiplayer synchronization'. The roguelite elements featured in the campaign will be fully implemented in the upcoming full release version. Please enjoy the solid foundation of this variant Mahjong in the demo first, and add us to your Wishlist to stay tuned for the various augments, systems, and campaign updates coming to cyberspace!

[Rules aren't meant to be followed; they're meant to be rewritten.]

A cyberspace within a space observatory where endless starlight flows. Victory here isn't decided simply by luck and point calculations. Whoever modifies the rules of the board first determines the outcome. Share authority with one of two opposing management assistant AIs, If and Else, and twist the rules of Mahjong with the Augment cards given each round to seize first place!

[Key Features]

■ Augments — 23 Weapons to Rewrite the Rules

At the start of each round, you select a rule modification card that applies only to you. 17 Common + 6 Guide-Exclusive, making a total of 23 unique cards. There are absolutely no "filler" cards.

■ System Overrides — Global Disasters that Strike Everyone

If Augments are your personal weapons, System Overrides are common variables that tighten the noose around all four players.

■ Guide Selection: The Chaos of IF vs. The Order of ELSE

The exclusive Augment cards you can draw will change depending on who you team up with in the lobby.

■ Custom Interface from Beginners to Veterans

Easy Explanation Mode: Turn this on if complex Mahjong terminology is unfamiliar. All Augments and System Rules are instantly translated into intuitive, beginner-friendly sentences.

4 AI Difficulties: Supports various AI levels, from aggressive bots aiming to minimize Shanten (tiles away from winning) to balanced bots that comprehensively calculate expected values, defense, and Augment variables.

■ Custom Room: Take Control of the Match Environment

Adjust the appearance rates of Augment cards by tier (Normal / Rare / Legendary).

Toggle System Overrides On/Off and adjust thinking time (Base + Banked time).

Set Tobi (Bankruptcy) match-end conditions and the number of Aka Dora (Red Fives).

Individually assign AI difficulty and personality (If / Else) for each empty seat. The entire aspect of the game changes completely based on the host's settings.

[⚠️ Warning (Please Read)]

This game does NOT feature a tutorial to teach the basic rules of Mahjong.

It is an "advanced variant" game that assumes you already know the basic rules of Riichi Mahjong. If you do not know how to play Mahjong at all, normal gameplay will be impossible, so we do not recommend purchasing this. We strongly encourage you to discover the joy of Mahjong first through excellent games like Mahjong Soul or Riichi City before coming here.
