Rather than increasing the frequency of wins or big wins, strategies target finding high-paying slot machines or managing your money to maximize your chances at wins while minimizing losses.
Nevertheless, some players like to use strategic approaches to slot play. That's as true with online slots as it has been for generations in live casinos. Nothing you do can change a slot's payback percentage.
With the exception of a tiny minority of skill-based games, slots are games of pure chance with results driven by random number generators.
