How long have you been playing online slots? It sounds like you may have a gambling problem to be this upset and lose that much money that quickly. I'd suggest looking into responsible gaming settings or quitting gambling altogether. The same thing happens at real casinos. The numbers are completely random and NOT in your favor. But the potential win makes it a fun pastime for many of us who enjoy losing small amounts of money over time to get the thrill of the chase.
I have cashed out more from eternal slots, mro and goatspins than any other casino site. It's not that I win more, but the low barrier of withdrawal of only 20 means I have many nights of micro wins. But I also have many nights where I can't hit anything for what feels like hours. Guess what? The local casino experience is the exact same. Same is the regular regulated websites that are legal in my state. It's stacked against you. It always has been, they are in business to make profit. I've lost 19 black jack hands in a row at a stay at an out of state casino. I've lost roulette 10 times in a row doing two columns with an actual wheel. Nuts stuff happens more often against you than for you. It's not a career. It's a pastime enjoyed by many. And I assure you this casino is legit, and has a very decent rtg of around 91-93 percent based on my gaming record. Not the best but certainly far better than most. They have no reason to con or scam you. They are going to win money over time by simply providing a fair experience.
Also, learn slot volatility and bonus frequency. There are games you can lose 100 dollars doing ten cent spins without ever seeing a bonus, and games where you can virtually never see a bonus and still hover at or near the same amount of cash.
Also, the visual you are getting is a trick on all slot machines. It's irrelevant what picture it shows you. The machine has already decided if it's a winner or loser already. You are going to see same or similar reels on many rtg sites because they don't come with the billions of different visual determinations of wins and losses, as that would make gaming over a website a massive memory drain. What image you see is irrelevant to whether a slot is "rigged" or not. All of them are rigged technically.
