About

Hangul Blocks

Features
Read full description

Learn to read Korean by playing. Hangeul Blocks turns the Korean alphabet (한글) into eight bite-sized games that teach you how syllables are built — not just memorized. Korean isn't random shapes. Every syllable is assembled from a handful of simple letters (jamo) that follow clear, logical rules. Hangeul Blocks makes those rules visible and turns them into play, so reading finally clicks. WHAT YOU'LL LEARN • Build syllable blocks from consonants and vowels • Tell apart the plain / tense / aspirated consonant tiers (ㄱ ㄲ ㅋ) • Distinguish look-alike vowels (ㅓ vs ㅗ) • Master the final consonant (batchim) and how it changes a syllable's sound • Read real syllables quickly and confidently • Grow your vocabulary with falling-word puzzles and spaced-repetition review EIGHT GAME MODES • Letter Blocks — build syllables from jamo • Consonant Tiers — plain · tense · aspirated • Hangeul Memory — flip and match the pairs • Vowel Match — tell similar vowels apart • Word Review — spaced-repetition flashcards • Final Consonant — master the batchim (Premium) • Reading Runner — read syllables on the run (Premium) • Syllable Rain — complete words as they fall (Premium) NATIVE-STYLE PRONUNCIATION Hear every letter, syllable, and word with clear audio so you learn the right sounds from day one. DESIGNED FOR BEGINNERS • English interface — start with zero Korean • Short sessions that fit into a busy day • Smart review that brings back exactly what you're about to forget • Progress syncs across your iPhone and iPad with iCloud FREE TO START — NO SUBSCRIPTION Five modes are free forever. A single one-time Premium purchase unlocks every advanced mode and reading challenge, removes ads, and gives you unlimited review. Buy once, keep it for good — there is never a subscription. Start reading Korean today, one block at a time.
