Idiom Crossword is a crossword built from Chinese four-character idioms (chengyu). Fill each empty cell with the right character so that every idiom across and down is complete. It is a fun way for Chinese learners and native speakers alike to practice idioms and their meanings.
Click an empty cell and type using your Chinese input method. Click Hint to reveal an idiom’s meaning when you are stuck.

You need a Chinese input method, such as pinyin, installed on your device to type the characters.
Beginner uses common four-character idioms, Intermediate adds less common ones, and Advanced uses classical idioms.
Yes. The meaning hints make it a good way to learn new idioms in context.
Only correct characters turn green, so a character that stays uncolored is a signal to rethink that idiom. You can change any cell until the whole grid is complete.
