Why do you fail single Kanji vocabulary words if you put in the kanji reading?

I too go very very fast on my reviews and I too remember having this exact problem. Sometimes I typo my answers, sometimes I か when I mean to け (I say the answers aloud as I type to help me focus), sometimes I enter the wrong answer before my memory kicks in properly… anyway, I can highly recommend doing this:

  1. Install Tampermonkey/Greasemonkey on your browser of choice
  2. Don’t install [OBSOLETE] Wanikani Override ("ignore answer button") - heed the wise advice below…
