Yuri, the former heiress of a company, finds her father's business bankrupt.
To repay the debts, Yuri must compete in mahjong and continue to win.
Can Yuri truly defeat her formidable opponents?
In this game, you control Yuri and compete in mahjong against various opponents.
If you manage to score the highest points by the end, you can repay the debts all at once. If any of the opponents surpass Yuri's score, it's game over for her.
Moreover, unlike regular mahjong, you can acquire skill points during the mahjong matches which Yuri can use to learn cheating skills.
Unlock these cheating skills and climb your way to victory against high-ranked tables with an advantage.
