Before you spin the reels in an online slot game, you need to make three decisions called betting options: the number of paylines, the coin size and the number of coins you wager per payline. Some slots will not offer the third option and instead fix the number at one. Very few casinos only leave the first option open.
Two important terms are the line bet (the amount wagered per payline – the product of the number of coins per payline and the coin size) and the total bet (the amount wagered per spin – the product of the number of paylines and the line bet).
You cannot win if the winning combination is in a payline that’s not enabled, so without enabling all of them you might get the winning combination and still receive no payout at all. Therefore when you choose the number of paylines you need to select all. It’s especially true for progressive jackpots because you get the jackpot when the winning combination is in the highest payline. Enabling all paylines can increase the total bet significantly. It’s better to lower your line bet but still keep all paylines.
The line bet depends on your bankroll and how many spins you want to play. For example, if your bankroll is 100 credits and you want to spin 100 times, the line bet should be 1. This can be achieved by 1 coin of 1, 2 coins of 0.50 or 4 coins of 0.25.
