Unity - Completed - The Fantasy World of Mahjong Princess [Final] [LSJ Productions]

Debating between giving it 2 stars or 3.

I started this because it’s a Riichi Mahjong game, and while I’m not high-level, I consider myself decent—I mostly follow Daina Chiba’s approach. The art is clean draw anime style with restrained animations that do the job (though this kind of art sometimes feels a bit flat to me). The H content is decent, and the story wisely doesn’t pretend to matter; it leans into a light, comedic tone that fits the premise. You play Mahjong, you unlock scenes, simple and fine.

The problem is the gameplay. At first it looks like a regular Mahjong title where you hope AI ramps up and you lean on fundamentals—aim for hands with good upgrade paths or secure quick, small yaku with Pinfu + Riichi. But as you progress the game pivots into stat grinding—mainly Luck—and the opponents have those stats too.

If you think you can ignore the stats, you can’t. High Luck warps outcomes... safe, standard lines become less reliable, while things like Chinitsu or even the occasional Yakuman, start appearing with suspicious regularity. At that point it stops feeling like Riichi Mahjong and turns into a grind, and it’s hard not to drop it unless you enjoy farming numbers.

TL;DR: Visuals do their job and the H content is fine, but the Mahjong gradually devolves into a Luck-stat grind. If you came to play or learn Mahjong, it’s not really worth it; if you’re here for the H content, grab a full-gallery save unless you don’t mind grinding.

Mahjong Princess is a game that does exactly what it says on the tin. No more, no less. You challenge girls to 2-player Japanese mahjong, and if you beat them you unlock an H-scene.

Art scenes are fantastic, with highly varied scenes and a wide selection of girl designs to collect.

As for gameplay, (Japanese) mahjong is a notoriously rule heavy game, and can be quite difficult for new players to learn and pick up. While the tutorial and help menu are both good reference tools, the game still requires some knowledge of defensive and efficiency strategies.

To remedy this, the game has a special mechanic where a player can spend in-game currency to rig their hand and start very close to a high scoring hand. I tested it a few times for the sake of this review-- I find it's not necessary if you know what you're doing, but still very useful if you don't.

In terms of mechanics, you can also use your currency to train your girls to up their stats. While not strictly necessary, upping your stats allows you some breathing room to make mistakes. Specifically, your starting HP is enough to be OHKO'd by a strong hand from the opponent. Since opponent HP's scale up with each successive battle, having the option to scale up your HP allows the player to trade blows with the opponent without requiring to fold when they are in riichi.

In terms of gameplay, there's a few minor inconveniences, like not being able to see your wait unless you declare riichi, or not having an option to turn off chii/pon prompts when your hand doesn't need them-- but these aren't big enough to actually impede gameplay.

In short-- the art is great. If you don't know what you're doing but you want to see the art, the game's built in mechanics give you a fair experience. But if you do know what you're doing and are up for a challenge, the game is still fun and fair just as a mahjong simulator.
