More Lines, More Chances to Win\n\n In general, the more lines you play, the more chances you have to win. But the more lines you play to, the more each spin is cost. Makes sense given that the house is more likely to lose when more lines are played.
No, slot machines do not pay more often with higher bets. The outcome of each spin on a slot machine is determined by a random number generator, so the amount of the bet does not affect the likelihood of winning. However, higher bets can result in larger potential payouts if a winning combination is hit.
