About Mahjong Efficiency Trainer

Dive into the fast-paced world of Mahjong Efficiency Trainer, the ultimate tile efficiency race for ambitious Riichi Mahjong players! Set in a sleek, minimalist interface designed for both clarity and speed, this browser-based indie gem challenges you to think like a Mahjong pro while battling the clock. As you face round after round of complex hands, your mission isn’t just to play—it’s to optimize, analyze, and make lightning-fast decisions that will shave critical turns off your shanten count.

Unlike classic Mahjong games, Mahjong Efficiency Trainer is laser-focused on improving your tile selection reflexes and strategic insight. Each hand drops you straight into the action, presenting branching paths with every discard option. The Trainer breaks down the math for you: how many tiles for each scenario can draw your hand closer to "Tenpai" (ready state), letting you instantly see which choice is most efficient. This is more than a game; it’s a full-scale training tool built for the competitive Riichi scene.

With hardcore difficulty and an unforgiving scoring system, every second counts. Your fastest runs are tracked, challenging you to outdo yourself—and the global leaderboard—one efficient tile at a time. Whether you’re grinding for improvement for your next tournament or simply want to experience the thrill of split-second theory-crafting, this trainer will push your limits. Fully mobile compatible and running seamlessly in any modern browser, it’s ready wherever and whenever you are.

Learn directly from the best as you access videos of top players dissecting their thought process, or contribute to the community by helping translate the game for global audiences. With open source code and a passionate indie spirit bubbling throughout, Mahjong Efficiency Trainer is more than just a practice tool—it’s a growing hub for Mahjong lovers who want to play smarter, faster, and with more heart. Are you ready to race toward mastery?

How to Play

To get started with Mahjong Efficiency Trainer, simply launch the game in your browser—no download required. Once inside, you’ll be presented with a random Japanese Riichi Mahjong hand. Your goal is to reach Tenpai (a ready hand) in the fewest discards possible by maximizing your tile efficiency on every move.

Controls are intuitive: tap or click on the tile you want to discard, and the trainer immediately recalculates your hand’s shanten (distance from ready) for all possible draws. Each move is a race against the clock, so make your decisions swiftly! The interface highlights tile improvement opportunities and lets you analyze results after every discard, so you’re constantly learning.

For beginners, focus first on understanding shanten and pay attention to which tiles connect your hand vs. which are dead weight. Watch the video guides linked in-game for extra insight from advanced players. And remember, there’s no penalty for replaying a hand—practice is key in mastering efficiency!

Whether playing on PC or mobile, touch and mouse controls are seamless. Keep an eye on the timer and leaderboard to push yourself for faster, smarter plays. As you improve, try experimenting with less obvious discards and compare their effects—soon, your instincts will sharpen for real-world Riichi matches.
