Slot games are solely luck based games, strategies don't work in this type of games, because they don't actually exist.
As gamblers we can strategize on the to go about our playing so that we don't end up spending all of our money in just a few rounds of the game, but when it comes to winning or losing, this two are completely based on how lucky the gambler is.
I agree with this, there is no strategy in this game. The Slot game is a game of calculating several rounds, so when playing Slots you really have to know and count several rounds, the winnings you will get, then this is the correct game. It really drains the players' minds, which is why sometimes players forget about it and don't find out how to play the game.
