Based on your experience while playing in slots, is the probability of winning measurable?
It depends on the definition of "winning," if it's max-win the help section of some provider states the probability of getting a max-win. Let's say 1/1,000,000 spins (one in a million). But, it doesn't mean that you will definitely get a max-win if you spin 1 million times. It's only on average after x billion simulation. That said, you can get a max-win even with one spin and get none even after one million spins.
I think we can't calculate winning (if you mean profit) probability without knowing the math inside the slots software, and how many spins you want to do. I only know that more people are losing than winning.
I was taught by a friend of mine, even in the competition it is not always possible to cover the losses suffered by the players, so I have to be wise to take steps. Is it really like that?
Yes, if you are often unlucky (like me). I think this week alone I burned more than $200 without getting any good result. So -$200 for me this week, so the worst scenario for me.
So do you think every player who plays slots will end up just losing a lot of their money?
Nope, it is based on your LUCK, and some dudes are luckier than other.
He thinks the same as I do. That slots are EV-games and therefore people who play they lose in the long run, even though in the short run they may win a jackpot or have a winning streak.
You know that's only in theory (and on average), right? Like in theory, your chance to win lottery is slim, slimmer than getting struck by lightning, EV- for sure in the long run. But for those who are lucky, they win and get EV+++.
It overwhelms me how this thread can have 25 pages of supposed "strategies" to win with slots when it is a game that mathematically gives you less money than you bet.
Please read the content first before commenting, that should be the golden rule of this forum. There are no 25 pages of strategy here, but this thread is for slots players to share their experience, bragging their winning, informing contests, discussing their favorite games, etc.
And what is the strategy for, then?
Please, read the content first.
Well, there is no "strategy" per se for this one click spin and pure luck-based game. However, you can use several playing styles for various scenarios you may encounter in this game.
Let's say you deposit $100 and want to play slots. "Strategy" here is just to give you some scenario on how to play the game.
You can do $20 x 5 spins -> not a good strategy IMO, but you can win big depends on your luck.
Or you can do $0.25 x 400 spins, or progressive $0.25 x 200 and then followed by $0.5 x 100.
It depends on what you play for. If you expect to get rich, yes, you are wasting your time. If you expect to be entertained or have fun, having the opportunity to win money in that session, but being aware that it is a game in which the odds are against you, no, you are not.
True, don't play poker as well, it's just a waste of time and money. Work harder and smarter! LuL
Competition is always nice, it can be an additional winning amount when we are lucky or it can be something like loss back while playing for the competition.
