If you’ve ever sat down to play Seotda and blanked on whether Ali beats Doksa, you’re not alone. The Korean hwatu card game has 29 distinct hand rankings — more than poker, and far less intuitive to memorize. Reading through a reference guide once or twice doesn’t cut it.
I built this because I kept hitting the same wall: I’d learn the rankings, feel confident, and then freeze up mid-game. The only thing that actually helped was being drilled on short, repeated quizzes until the hierarchy became instinct. So I made an app that does exactly that.
The app, originally named 섯다 랭크 트레이너 in Korean, is now available on the App Store as a free download.
What It Does
- Hand Reference — All 29 rankings organized into four groups: Gwangttaeng, Ttaeng, special Geut hands, and standard Geut hands. Tap any entry to see the actual hwatu card combination, its rank position, and a plain-language explanation.
- Three Quiz Modes — Hand Identification shows you two hwatu cards and asks you to name the hand. Head-to-Head Comparison puts two hands side by side and asks which one wins. Counter Hand gives you an opponent’s hand and asks what beats it — the closest thing to live-game reflex training.
- Hand Evaluator — Pick any two hwatu cards manually and get an instant verdict: what hand it forms and where it sits in the ranking order. Useful for settling disputes at the table.
- Progress Tracking — The app tracks your correct answer rate per quiz mode so you can see where your weak spots actually are.
- Real Hwatu Card Images — The card art comes from original images licensed under KOGL Type 1 from the National Folk Museum of Korea. These are authentic hwatu illustrations, not generic icons.
Everything runs offline. There’s no account, no login, no data collection. Your learning history stays on your device.
Who It’s For
This app is squarely aimed at anyone trying to get competent at Seotda. That includes complete beginners who’ve never touched hwatu cards, intermediate players who still second-guess the mid-tier rankings, and poker players trying to rewire their hand-reading instincts for a completely different hierarchy. It also has full English support — terms are rendered in romanized Korean (Gwangttaeng, Ttaeng, Ali, Doksa, and so on), which makes it a reasonable entry point for non-Korean speakers interested in the game or in Korean card culture more broadly.
Quiz sessions are designed to run in one to two minutes, so this fits naturally into dead time — a commute, a break, five minutes before the game actually starts.
If Seotda is on your learning list, version 1.0 is free on the App Store with banner ads. Give it a try and see how many rounds it takes before the rankings finally stick.
