Btw, not sure how true it is, but I hear it's easy to win at slots when the game has just been listed (new).. and this would be the perfect time for everyone to put this theory to the test...For science

I play games because I want to explore games that are new with me or when I want to have entertainment. I don't play games because of any theory or fallacy of big winning chance, it's untrue. At all casinos, they run business for profit, and gamblers have to be aware of this fact, so there is no easy chance of winning especially winning big and more importantly winning against the casino in long term.
I don't take risk to test any theory or fallacy as I value safety of my fund than chance of beating a casino, or using any playing theory well for profit.
Many gamblers believe the same, but this is not true, obviously. It’s just another gambler’s fallacy.
Whether the game is new or has been around for a too long does not change anything. This doesn’t affect the chances of winning in any way. What really matters is the game’s RTP and volatility.
But why not? There’s nothing wrong with trying to test this theory (as the occasion arose) as long as you enjoy playing those new games and not spending on it more than you can afford to lose

There is nothing wrong to test a new game, test a new theory, but let's do it with money people afford to lose, and surely with very tiny part of their gambling fund and never let it affects their whole gambling fund as well as general finance.
