Apologies if you’ve seen this before. A game from tudorbritain.org, with sound. Looks simple, but not so on trying the thing. I still haven’t won the third bout. Anyway – might be something for the slow work day (with the sound off, o’course). 
Not bad for a 5-minute fix
Choose the top left knight, Thunder as your horse, Elizabethan jousting armour, and always go for the chest
If you get too frustrated trying to beat the third one, this worked for me:
Ride Thunder.
Wear Soldier’s Armor.
Aim: 1st: body
2nd: head
3rd: body
Ah, you beauties, Quartz and QuizCustodet! Thanks, mates!
