Sonic Blast Man is an arcade punching game where you put on a boxing glove and slam your fist into a thing which senses the hit. I broke my wrist on that game many years ago. I didn't know it at the time. It just felt like a dull ache. So I then went on to play the arm wrestling game. That definitely didn't help. It got worse in a short time and by the end of the night I was cradling my right wrist in my other arm to relieve the pressure.
I had to wear a cast for 5 months until the hairline fracture healed.
