Good, but not highly engaging – Kanji Solitaire Review
With little but what you already know to go on, it's a lot like dull flash cards. I don't mean to make it sound awful, since any way to make memorizing Kanji less tedious can really help.
Just, while I enjoy this it feels like the only in-game guidance is being punished when you make a mistake. Getting it right should feel better.
