Since you at least know the layout. Typing of the Dead can be fun for forcing you to start using more fingers as things come at you. I needed to force myself to get better in order to make sure I could pass a timed typing speed and accuracy test for a data entry job. Played it a little every night for at least a week before my interview. I was still kind of slow, but was much more accurate. Which got me into a position that corrected or found missing information from the main data entry folks. If arcade zombie games aren’t your thing, there are some other good games mentioned in the other comments.
I get those a lot from other sites (weirdly YT Music doesn’t on FF or Zen) like Amazon Music (even when just trying to buy a digital track or album). Weirdly the sites will act normal for a moment or two before removed about my browser not being “updated” or otherwise Chromium-based. We managed to break the internet being coded for IE, but allowed Google to openly make the new IE. Safari seems to work for some of the sites, but that is just because Apple made all the iOS browsers use Webkit with custom skins on one of the top selling phone/tablet options.
