About WazaDeck
WazaDeck is the fastest way to learn and memorize Judo techniques. Built on the official Nage-Waza and Katame-Waza classification, WazaDeck turns technique study into a tight, repeatable flashcard game — so names, families, and categories actually stick. FEATURES • Flashcard quiz — see a technique, recall its name, family, and category, with immediate feedback on every card. • Learn from misses — wrong answers reveal the correct technique and where it belongs, turning mistakes into memory. • Technique library — browse the full catalog of Judo throws and grappling techniques, organized by official family. • Track your progress — build daily streaks and watch your stats climb. • Leaderboard — see how you rank against other judoka. • English & Portuguese — study in either language. Whether you're prepping for a belt exam or sharpening your knowledge for the mat, WazaDeck keeps study fast, focused, and effective.
