There are three steps you can take to tell when a slot is nearing the jackpot. First, you need to check the payout percentage of the machine. If the payout percentage is low, it may be a loose machine, so you should stay away from it or find another machine. Second, look for any announcements about recent big wins.
Slot machines are governed by Random Number Generators (RNGs), so any spin can be a big winner or a loser. However, if you notice that a machine has more than a few loose spins, it might be close to hitting the jackpot.
Third, try to play on multiple machines at once. This will maximize your chances of winning. It is best to play with maximum coins if a machine has a jackpot. Also, check the payout table, as it will show the probability of winning combinations.
Fourth, observe the reels. If they wiggle or appear to have a pattern, that’s the best time to bet your maximum amount. Once you notice a pattern, bet your max and try to hit the jackpot. You’ll get an idea of when the jackpot is approaching, and you’ll be more likely to hit it.
