It is really not surprising to see a 40 consecutive losses especially in dice. Even in slots which often gives small amount just to break the dead spin streak gives 30 plus consecutive dead spin (read streak) when we are spinning for too long. I always experienced that scenario since I am the kind of slot player that seldom hop to different games and often ends up playing in a single slot game.
In slots having a lot of consecutive losses happens pretty frequently especially on high volatile games. On the in-house games like Dice or limbo or crash it can also happen but more rarely. The longest "bad" streak I saw was about 20-25 consecutive losses (luckily for myself I was not playing Martingale than or otherwise I would have busted my entire bankroll lol).
Not usual but it can happen, 40 red losing streaks are something that you can't imagine happening if you are the one who's playing, those who are using martingale system who hopes that they can recover their losses after winning their next bet would be empty if that long losing streak take place.
Though, if you experienced that long red losing bets for sure the aggressiveness inside you will lead you to lose more than your expected budget.
You're so unlucky if you experienced such and it might discourage you to play that particular game again. Well, I don't stay in games that giving me bad experience, the reason why i'm not a fan of slot. Fortunately on the game where I usually play (live games), I never encounter yet of having consecutive losses (20-40 like others have experienced already). But even so, the ending is still favor n the house as i'm often finishing my gambling time with losses.
