Showdown Tournament

=============================================

Goal: Declare Riichi or Showdown (Tenpai: One Tile Away from Winning) before you run out of turns, and score enough points before you run out of games. This is a Mahjong roguelike where your extensive knowledge of Japanese Mahjong hands—while not required—will be greatly rewarded. Otherwise, you can gain practical experience through the Showdown Tournament, which helps you learn and memorize the numerous hands—known as Yaku—in Japanese Mahjong, while encouraging you to aim for higher scores, unlock achievements, and discover hidden content. Detailed explanations of each yaku are included and categorized for easier memorization.

The Showdown Tournament provides many tools to help you succeed, provided you manage your resources effectively:

Sign Sponsors that reward you when you meet their conditions.

• 150 Sponsors designed to synergize with each other and with various yaku. 

Modify the tiles in your wall with Fluffies to score your favorite yaku more consistently.

• 22 Fluffies with special powers that add, remove, modify, and enhance tiles in your wall.

Gain power-ups by reading Books.

• 8 Books that boost yaku scores across different categories.

Use the power of Friendship to cheat without altering the tiles in your wall.

• 28 Friends who find different kinds of tiles by following your hints.

Battle through different Bosses to win the tournament

• 30 Bosses, each presenting a unique challenge.

Consume Food to gain permanent buffs during your current run.

• 24 Food items, each granting specific benefits.

Master Mahjong through increasing difficulty levels, each designed to reflect advanced rulesets such as furiten.

Tutorial

=============================================

If you are just starting out and trying to learn Mahjong, we got you covered!

"I don’t want to have to read the phone book to play some Chinese solitaire." —Some guy referring to a Mahjong rulebook.

And that guy was absolutely right. I didn’t just read the phone book—I turned it into an 11-step interactive Mahjong tutorial so you don’t have to. My name is Mahjong Sensei, and I designed this tutorial to guide you through the different suits and actions in Mahjong with a clear, step-by-step approach. 

By the end of this tutorial, you’ll have the confidence to know you’re fully justified in slapping your opponent’s hand away with your tile pusher when they try to Chii against your Pon.

Major benefits of learning Mahjong:

• You can enjoy and understand Mahjong anime and movies.

• Gain knowledge that enables you to play other Mahjong or Mahjong-inspired games.

Fringe Benefits of learning Mahjong:

• Impress your Asian in-laws or crushes who play Mahjong.

• Make three friends (or nemeses) in a single game when playing IRL.

• Master the Japanese and Chinese characters for numbers 1 through 9—arguably enough to claim language proficiency on your resume.
