That’s just a really bad run of luck maybe? You need to vary the casino’s that you play at and also vary your games. I play across 6 casino’s, can be a sucker for going on the same games but I do try new stuff. I’ll usually have a cash out each month but there have been recent times of depositing and no bonuses happening. I might play the games I like at one casino and they are doing nothing, switch over to another and the same games are doing something. All hit and miss but you must have variety in your choice.
If a game isn’t bonusing, have the will to close it and move onto something else and take the loss. Go back to it you build your balance back up.
