There are dozens of decks. You can start with JLPT Tests from N5 to N1, or try out Kentei or other more specific stuff. It’s fun and you can learn kanji and vocab in a natural way because the cards are placed randomly and the meanings are also shown after you pass a card, which after a while get ingrained in your brain. It’s good practice, try them out 🙂

The idea is pretty good, but I just tried playing it and you have to type in the exact syntax in english which is present in the card or else it’s considered wrong.
