In Armor Games’ free online simulation, “Dark Cut,” you play a medieval surgeon, summoned by your king to perform offbeat, primitive surgical procedures — like removing an arrow or lancing a nasty boil or dispensing with a…well, I won’t say.
It’s a relatively easy operation, because you’re given instructions virtually all the way through it and the “game” doesn’t involve much challenge — all that’s required is a steady hand and a dark sense of humor. What makes it worth wasting your precious time is the disturbing surprise of each patient’s symptoms and the anticipation invoked by each repulsive-yet-cute cartoon graphic that goes along with it.

If this sort of thing is your cup of glee, you also might have some fun with this medieval surgery mad lib. It was designed to be educational, but I recommend printing it out and using your own randomly chosen words!
