Learn Japanese vocabulary by real-life topic: workplace words, everyday words, onomatopoeia, adverbs, slang. Pick a level and play a few minutes a day.
This topic collects every game where the task is remembering what words mean. Most are industry vocabulary — the words you see on the work schedule, not the ones in textbooks.
The rest are words used off the clock, the kind textbooks skip because they're not on any exam: onomatopoeia, adverbs, slang, and katakana words whose meaning drifted far from the original English.
Learning by topic is faster than learning word lists sorted by level, because words in one session are about the same thing and anchor each other.
