Description by Cross Field Inc. Written by the developer, not by AppBrain. Click to read.
Mahjong Duels Koo is a Mahjong application game for 2 players.
This free app offers an exciting original rule set that is different from traditional mahjong, allowing you to enjoy an exciting game of Mahjong.
Share the new Mahjong fun with players from all over the world.

■Features
・A strategy that is deepened by its own rules!
Based on traditional mahjong rules, the application adds unique elements to create a completely new mahjong experience.

・Easy to play with short term settlement!
The original rules, which use only Pin and Honor tiles, make it easier to form a winning hand than in regular Mahjong.
This shortens the time required for a game and makes it easier to play without stress.

・It is easy to get high-scoring Yakus! High-risk, high-return matchups
The original rule using only Pin and Honor tiles guarantees that the hand will be at least Half Flush, and makes it easy to challenge Full Flush
This rule allows players to enjoy dramatic developments with high risk and high return.

・Original element "Shikigami"
Introduced the "Shikigami" skill, which further enhances the strategic nature of two-player games.
The strategy and reading of the game will be further expanded by the tactics used in various phases and the formation of the Shikigami.

・Heated Online Mode
With the Online mode, you can enjoy online battles with other players.
Aim for the top of the monthly ranking by accumulating victories.

・Gorgeous production
When Ron or Tsumo is played, the game adds a spectacular celebration of the player's achievement in the game. Each move is more vividly and dramatically colored.
