Blocks fall and you combine them to form Chinese characters known as hanzi or words! This is great for you if: 1) You are new to Mandarin Chinese and want a fun way to learn a lot of hanzi easily; or 2) You are advanced in Chinese and want a fun game to test and sharpen your skills; or 3) You love brain training apps and would like one where you train your brain and learn a language with very little effort at all and a lot of fun -- it's BrainTraining++! More: Thanks for checking out my app! I'm a solo-developer trying to make learning fun and easy! :-D Blocks with Chinese hanzi on them fall and you try to eliminate them by forming words and and activating hanzi-related powerups by combining them into more complex hanzi. It's a great way to learn hanzi for beginners, a fun alternative to flashcards for advanced learners as you can import your study decks, and a fun game overall! :D There are also fun minigames and focused learning tools to keep you learning hanzi and words as you play! This works great in conjunction with other apps and resources! Tired of playing games where you spend a lot of time and have nothing to show for it? You compare yourself before and after and you're just ... less bored. Well, if you'd rather spend your time more productively and have fun, try Chinese Drop where you can learn how to read Chinese without any effort at all! You'll find yourself in a relaxed state picking up a lot of hanzi and words almost passively! No stress, only fun! Chinese hanzi are the ideograms found in Chinese that are kind of like letters, but represent an idea, like gold, fish, sun, etc.! Now learn them in this falling block puzzle hanzi game where you'll find emoji to help you learn hanzi, POWERUPS that relate to the hanzi, and a fully functional glossary. You can even narrow down your learning list to hanzi for the HSK! You can even review hanzi from your text book lesson, like Integrated Chinese! You can also play in a learning mode with more time between hanzi! Learning hanzi has never been easier or more fun! Learn Chinese hanzi by dropping blocks to make hanzi and words! Make hanzi from their parts and words from other hanzi! Blow them up by making words or filling your limit meter and they all EXPLODE! Learn Chinese hanzi for fun or proficiency. Every time you make a word or hanzi, its meaning is spoken and you also hear the pronunciation of words. You also learn how to make hanzi from their parts. You can find links to stories, links to practice sentences, as well as animated stroke order diagrams and a list of your favorite hanzi. Open to all skill levels! It starts off easy and gives you hints when you're stuck. Keep playing and you'll find yourself recognizing more and more hanzi!
