SyllaBrawl is built on one idea: you don't learn a language by recognizing words. You learn by retrieving them under pressure. That's what a duel is. Two minutes, seven rounds, alternating turns with another player or a bot. Answer faster and more accurately than your opponent and their HP drops. Miss a word and it comes back in a no-pressure drill, teach-first. The pressure is the point. The mistakes are the engine. — LANGUAGES — Starting with Korean and Thai. More on the way. Korean — 17 units, 155 hand-authored lessons. Hangul from day one (you read 안녕 in your first lesson), through politeness, conjugation, and connectives. Thai — 16 units, 109 hand-authored lessons. Five tones, three consonant classes, and the Thai script taught as the system that makes Thai work. Every lesson is hand-authored with an intro, a "why it matters," and example sentences that recycle vocab you already know. — PLAY — Friend duels, ranked matches, async turn-by-turn play, and bots tuned to your level. Climb from Tin to Diamond. — PRACTICE — For when you don't feel like fighting. Same lessons, no clock, teach cards on every miss. — PRICING — Free to play, A one-time $2.99 purchase removes ads across all your devices. No subscription. No paywall on lessons. Built for iOS 17 and later.
