Tazza: AI Hwatu Coach

Tazza is an app for learning Go-Stop, the Korean flower card game, and proving how far you have come. Scores are learning points only, and nothing of value moves between players. What remains is pure judgment.

AI Coach Mode
On every turn, an on-device AI highlights the card it recommends and explains the reason in plain language. "Two brights already. One more and you have three." "Your opponent holds two blue ribbons, so do not hand them a third." Go or stop decisions come with a comparison between the points you lock in now and what you can expect by continuing.

Daily Same-Hand Challenge
Every day all players receive the identical deal, the identical draw pile, and the identical master AI opponent. Rankings are decided by skill, not by luck. Your score combines the points you win with an accuracy bonus.

Rankings and Contested Titles
Compete on daily, weekly, monthly, and all-time leaderboards. Six contested titles can be held by exactly one player each: Tazza of the Week, Precision King, Comeback Artist, Bbeok Hunter, Go Master, and Iron Wall. Post a better record and the title changes hands on the spot.

Replay and Accuracy
When a hand ends, step through it card by card to see exactly where points slipped away. Accuracy is measured as the expected-score gap against the AI's best move, which strips luck out of the result. A weakness report tells you whether discarding, capturing, or go-stop timing is holding you back.

Eighteen AI Levels
Play a quick hand against any of eighteen levels, from Beginner to Grandmaster. Take promotion tests to certify your rank and collect thirty-two achievement titles along the way.
