@alexhall I'm sighted and I don't use a screenreader. You don't type anything to play. Each game is a few words that you must transform into a target word. You do so by selecting one or many consecutive words, and choosing a transformation.
So you click on "sword" and a few synonyms pop up; you choose one and replace the word. Or click "war runs backwards" and replace it with "raw". I assume the website is unfriendly to screenreaders :(
