Since we came out from pandemic, I always verify my bet before playing them to see some error to be correct in the gambling center before playing the game which is really helping me to win most of my game since we came out from pandemic.
I do not often check or say rarely do it just because in the end its a luck in many games which help you win it. Also, what is the outcome like how many times were you able to report the error of the total bets you verified because at times you may bet a lot like in dice etc so cannot go and verify each bet.
If you make like 100 bets, I think that's 100 times of verification, it's too time consuming, a reputable site would not attempt to scam their bettors, otherwise they will loss their opportunity to make money. In games like luck based games, sites always offers a way to verify it's fairness, but I believe majority of the bettors would not bother to verify their bets, unless maybe they risk a big amount of money in a bet.
