When something is determined by luck, then strategy won't work because luck determines everything. What strategy will we employ to win the next round of slots? I don't think there's anything we can do.
Many people claim strategies, tips, and tricks for winning, but in reality, they lose more often. Perhaps they were lucky when they used a particular strategy, but they attribute it all to strategy. I don't blame them, nor will I condemn their beliefs, but I personally don't believe it's feasible.
When it comes to slot machines, it's virtually impossible to come up with a real strategy because they operate on a fixed algorithm. And even if you somehow managed to understand that algorithm , which is highly doubtful and unlikely, it still wouldn’t allow you to win consistently. So building a strategy around such games is a myth and self-deception. I can confidently say that not a single millionaire has been made this way, except the casino itself. The only real strategy here is to clearly define the amount you're willing to spend on a game of chance. If you're lucky, you win. If not ,well today just wasn't your day.
