In fight I think of it like this: A normal hit is when you hit their skin, very little damage. Bleed is when you get through their skin, critical is when you hit their internal organs and instant kill is when you punch a hole through their heart.
I noticed a bug in the casino. When I bet 3 tokens and I roll 3 nothings, I get 3 free spins. But I have +134% payouts so I should get 4 free spins instead of 3. Pls fix
