• A daily challenge that changes every day
• Progress broken down by domain, not one vague number
• Hints when you're stuck, skips when you're done

LEARN SOMETHING WHILE YOU PLAY

Every level you solve ends with a card about Japan: a word, a place, a piece of history. Washi paper. Mushin. Nachi Falls. The Tale of Genji. Small things, worth knowing.
