There are a few ways to estimate a slot machine's payout percentage without actually playing it. The most reliable method is researching the machine's approved gameplay parameters from the gaming commission in that jurisdiction. You can also try observing the activity around that machine - if others are winning often and sizable amounts, the payout is likely higher. The precise math and features also offer clues. But admittedly this isn't foolproof without actually feeding coins in yourself and tracking results over many spins. The best players combine research, observation and experience to narrow down the range before placing any bets.
