Every stage holds five kanji and asks five questions. Pick the reading from four options, or press 1–4.

Four correct out of five (80%) clears a test stage. Practice mode always clears — it shows the reading, runs no timer and costs no HP.

Every miss goes into your review queue: the kanji returns 3 questions later, and 5 questions later if you miss it twice. Three correct answers in a row and it is marked as learned.

Review mode pulls the five kanji you have missed most.
