Seotda Rank Trainer

Seotda Rank Trainer is the fastest way to memorize the rank order of every hand in Seotda β the classic Korean two-card gambling game played with hwatu (Korean flower cards). Seotda has more hands than poker (29 in total: special pairs, ten "ttaeng" pairs, six special "kkeut" combos, and ten regular "kkeut" hands), and the order isn't always intuitive. Reading a rule book is slow. Short, repeated quizzes are how you actually internalize a ranking system. That's exactly what this app does. --- WHAT'S INSIDE --- β’ Reference β All 29 Hands at a Glance Every hand category is organized into clean groups: Gwangttaeng, Ttaeng, Special Kkeut, and Regular Kkeut. Tap any card to see its tier, the actual hwatu cards that form it, and a clear explanation in your language. β’ Quiz β Three Modes That Cover Every Skill - Identify β "What is this hand called?" Recognize a 2-card hand from real hwatu artwork. - Compare β "Which hand wins?" Two hands side by side, pick the winner. - Counter β "Which hand beats this?" Train your reflexes for table play. β’ Hand Evaluator β Quick Lookup Tool Pick any two hwatu cards and instantly see what hand it forms and where it sits in the ranking. Perfect for settling table disputes or just satisfying curiosity. β’ Stats Tracking See your accuracy per quiz mode. Watch your numbers climb as you learn. --- WHY THIS APP --- β’ Real hwatu card artwork β sourced from the National Folk Museum of Korea (KOGL Type 1 license), not generic playing-card icons. β’ Built for repetition β short quiz sessions designed for 1-2 minute learning bursts. β’ Bilingual β full Korean and English with romanized hand names (Gwangttaeng, Ttaeng, Ali, Doksa) so non-native speakers can learn the proper terms. β’ Offline β no account, no login, no data collection. All progress stays on your device. β’ Light and dark themes. --- FOR WHO --- β’ Anyone learning Seotda for the first time. β’ Casual players who can never remember whether Ali beats Doksa. β’ Players coming from poker who want to map intuition over to Korean rules. β’ Travelers and language learners exploring Korean card culture. --- NOTES --- This app is a learning tool, not a gambling app. There is no real-money play, no in-app purchases, and no online multiplayer. It is designed for general audiences and is not intended for use by children under 14 without parental supervision. Free, with non-intrusive banner ads.
