Bro, it's same experience with every casino except you are extremely lucky to win so much for that day and maybe you didn't repeat the casino again, because another thing I observed is that, after winning so much today and you go back the next day with the hope that you will win just like the previous day, you can lose so much that day and will even regret why you gambled that day or you could question if the game was fair or not

. I know what I experienced but seeing how some other users made same complaints, I just concluded it's so common.
It’s very rare to have a winning streak on daily basis because casino games use an RNG with house edge which means you higher chance of losing.
Continuously winning for a long term means your luck is set to max for beating the casino odds most of the time while you should lose frequently based on stats.
You will likely lose in more days than winning based on stats so it’s normal that you will lose after you manage to win since winning is just a rare occasion in gambling.
That's true, I know all of these things. As a matter of fact, there's how a gambler will win their bets and the casino would limit how much they can stake at once and that clearly tell us that the casino doesn't like it when a gambler wins so much that they expect.
