Choose From and To
English supplies the center prompt. Choose Simplified Chinese, Traditional Chinese, Japanese, or German for the answer tiles.
Choose a Vocabulary Track
Language Learner mode uses HSK 1 through HSK 7-9 for Simplified Chinese, TOCFL Novice 1, Novice 2, and Levels 1 through 5 for Traditional Chinese, JLPT N5 through JLPT N1 for Japanese, and CEFR A1 through CEFR C2 for German.
Choose a Difficulty
Learner tracks are ordered from easiest to hardest. Native mode offers Native 1 through Native 10 based on word frequency, from common vocabulary to rarer terms.
Explore every learner and Native level, then open a ready-to-play preset for the language you are studying.
Harder vocabulary earns more. Language Learner levels scale from 1 to 10 base points. Native 1 starts at 15 points and each level adds 5 points, reaching 60 points at Native 10.
Consecutive correct answers build your combo. Combo 5 adds 3 seconds, Combo 12 adds 5 seconds, Combo 20 adds 7 seconds, and every 10 correct answers from Combo 30 through Combo 100 adds 10 seconds.
Every wrong answer removes 10 seconds and resets the combo to zero. Fast guessing can therefore end a run sooner than careful recognition.
Every combo time-bonus milestone also awards one random lifeline. Lifelines fill the lowest empty slot, duplicates are possible, and you can hold up to nine at once. If every slot is full, you still receive the bonus time.
Tap an active lifeline, or press its numbered slot from 1 to 9 on desktop. Passive lifelines activate automatically.
Removes half of the remaining distractor tiles, leaving the correct answer on the board.
Your first wrong selection is removed without a time penalty or combo reset, giving you one more attempt. Only one can trigger per puzzle.
Briefly highlights the row or column containing the correct answer, choosing the direction with the most visible options.
Replaces the current puzzle without awarding points. The rerolled puzzle stays in your review but does not affect correct answers, incorrect answers, accuracy, score, or combo.
Play on a 4x4 board with 12 answers and three minutes on the clock. Standard mode uses the normal score for your selected vocabulary level.
Expand the board to 6x6 with 32 answers and multiply every score award by 2.
Start with only 90 seconds and multiply every score award by 2.5. Rampage and Berserk can be combined for a 6x6, 90-second run with a 5x score multiplier.

Radical Rush uses English prompts with Simplified Chinese, Traditional Chinese, Japanese, or German answer tiles.
Language Learner mode follows established study levels: HSK for Simplified Chinese, TOCFL for Traditional Chinese, JLPT for Japanese, and CEFR for German. Native mode groups vocabulary into ten frequency-based levels, progressing from common words to rarer and more specialized terms.
Every consecutive correct answer increases your combo. Combo 5 adds 3 seconds, Combo 12 adds 5 seconds, Combo 20 adds 7 seconds, and every tenth correct answer from Combo 30 through Combo 100 adds 10 seconds. A wrong answer resets the combo and removes 10 seconds.
Rampage expands the standard 4x4 board with 12 answers to a 6x6 board with 32 answers and doubles your score. Berserk reduces the starting time from three minutes to 90 seconds and multiplies your score by 2.5. Enabling both creates a 6x6, 90-second game with a 5x score multiplier.
Yes. The completed game review preserves every board and shows the correct and selected answers. Available readings and translations can be inspected from the tiles, along with each round's score, answer time, and combo bonus.
The game repeatedly asks you to connect a written term with its meaning under time pressure. This practices rapid word recognition, reinforces form-to-meaning associations, and exposes uncertain vocabulary that you can revisit in the game review. Higher levels introduce progressively less familiar words as your recognition improves.
Start with the learner level you are currently studying. If most tiles are immediately recognizable, move up one level. If you are frequently guessing, move down and build accuracy first. A suitable level should challenge your recognition without turning every round into chance.
Yes, when the language combination is available. Changing direction alters the cue you see in the center and can reveal vocabulary that is easy to recognize in one direction but difficult in the other. Practicing both directions creates a stronger connection between the terms.
No single vocabulary game covers every language skill. Radical Rush is best used for recognition speed and vocabulary reinforcement alongside listening, reading, pronunciation, writing, conversation, and grammar practice. Short, regular sessions can support those broader learning activities.
