A slot machine strategy that many players find effective is the 'bet sizing trick'. This involves keeping your bet size the same until you experience around 10 to 15 spins without a win. At this point, you increase your bet size until you hit a big win or enter a bonus round. After the win, you then reduce your bet to a third of what you were betting for the next 50 to 75 spins before repeating the process. While this strategy doesn't guarantee wins, it's a method you can try, especially on three-reel slot games like 'Ten Times Vegas'.
