Hello,
I hate to say it in such a quick succession, but with all respect, properly licensed casinos just do not need to "rig" the game. As long as the house edge is always on the casino's side, the longer you play, the more likely you are to end up without money. Speaking of which, how long have you been playing there, what games with what RTP value?
Just a brief recap if you don't mind:
slots have different RTP, you want to play slots with higher RTP (around 96%), because they pay more
you need to pay attention, because some game providers allow casinos to decrease the RTP on their slots, so it can happen to you, that the same slot can have different RTP in 2 different casinos. Anyway, good casinos always show you how much is the RTP on a specific game
there are high volatility and low volatility games, when you play low volatility games, you win quite often, but the winnings are often lower than your bets. When you play high volatility games (for example jackpot games are often high volatility games), you can have a dead spin after a dead spin, maybe 50 in a row, but then you enter a special bonus feature and win a big part of you losses back. Anyway, if you stop playing earlier, you feel like the slot didn't pay you anything
Perhaps you have been quite lucky until you played in Boomerang.
Rather than considering games rigged without proof, which is usually not found, how about trying a hobby without neccessary risk? Just asking. You don't sound like having much fun.
