Nope I don't verify every bets as a gambler I just enjoy every round as much as I could.
Besides I only play on trusted and well known gambling sites I don't want to play on new sites that doesn't have much info or player.
Once in a while if losing continuously then do just check just to see if everything is fine. I also play on known ones only so that even if not verifying I know they are genuine and not getting any sort of rigged as reputation is on stake of such gambling sites. Also, since just not playing for money so does not even hurt much on loss.
