Senior Brain: Hangul Code

🧠 Refresh your visual focus and pattern recognition in just 3 minutes with daily Hangul cipher workouts! 🧠

Senior Brain: Hangul Code is an engaging, accessible cognitive workout designed for seniors and adults to sharpen visual discrimination, pattern synthesis, and mental agility through the combinatorial beauty of Korean syllable structures.

Inspired by the classical Fanqie (反切, Banjeol) phonological synthesis method, this app challenges you to examine two characters, extract the initial consonant from the first and the vowel/coda from the second, and verify the resulting syllable equation (A + B = C). No knowledge of Korean is required—gameplay relies purely on observing visual shapes, distinguishing geometric components, and testing your pattern-matching reflexes!
