In conclusion, if you are already having a rough time on playing same game over and over despite you have a good experience on it before. Trying new games to you and taking break will help you to snap out of your losing streak because chasing losses usually make us trap on our losses.
In your case, how do you approach when you are on losing streak so badly on specific game. Does changing game works for you?
Previously I don't know if someone has told you this. That it doesn't all of the time work in this way as it did for you by virtue of your changing game from blackjack to slot. Someone somewhere could have tried this strategy after going through series of losses and still didn't change the outcome to any win. It's same as someone having a rough time with a particular slot machine at the casino after several session and then decides to change to use a different slot machine and still didn't get a smooth outcome.
By some way of luck we could chose to change our position about a game and hit a win but this is not guaranteed as it has the propensity to lead to further loss. The safe option to fall on when the loss has become a continuous one after several session is to take a break. Taking a break is a powerful strategy in preventing unwarranted losses. That's what I do when the streaks are not going in my favor. I don't push it.
So do you accept calmly the lost sessions when luck is not favoring you as you must be a genius if you can do that.Most people including myself I simply get mad when the lost sessions are coming in a consecutive way and after I see that the only thing I do is to go all in hoping to recover my lost amounts which only lead to even more bad losing.I am trying hard from quite sometime to stop when this thing happen yet I have never been able to accept lost sessions and bad luck calmly,I always get mad while I lose and I know very well my chances are totally against me when I gamble yet I seem to not keep calm mostly because the slot machines and most casinos do not give a damn about the RTP nowadays,they take your money in the fastest possible way while not keeping you entertained by giving you a deceiving win in the middle of such sessions.So the only thing to stop the curse of losing streak is to stop completely and not just take a break.
