What Are Slot Paylines?

Slot paylines also known as winning lines or betting lines are specific patterns designed to detect a winning combination. In most classic slots, paylines are simple horizontal lines that run across the middle of the reels. But modern slots can have multiple paylines crisscrossing the reels in straight, zigzag, diagonal or V-shaped arrangements.

Depending on the game, these winning lines can be fixed or flexible, and, to make things even more interesting, some slots don’t even have paylines anymore. These are better known as grid slots, or slots with the famous Cluster Pays mechanic, where a win occurs when you form a cluster of winning symbols.

How 20 Slot Machine Paylines Work

When playing multi-line slots, your aim is to land a set number of identical symbols on an active payline, but for it to register a win, the winning symbols need to land in a specific order. In most 20-line games, you’ll want to line up 3, 4 or 5 identical symbols from left to right horizontally or vertically, starting with the leftmost reel. If you hit a winning combination, the game will calculate the outcome based on the paytable and add it to your cash balance.

How Many Slot Paylines Can You Have?

Slots with 20 lines are some of the most popular games, but you can also play games with 5, 10, 50, 100 and more paylines. In some slots, particularly those that use the famous BTG’s Megaways mechanics, you can unlock as many as 117,649 ways to win. There isn’t a rule as such of how many paylines a slot must include, but these are some of the most popular types:

Most games, including 20-line slots, have the same basic rules on how to play them – you place your bet per spin, push the spin button and match identical symbols on an active payline. If you’re lucky, you’ll also extend your gameplay by triggering a bonus round. Just beware that due to extra paylines, your bet per spin will likely be higher than classic 1 or 3-line slots.

The trick to having the best experience is to choose the right online casino. Many casinos offer sign-up bonuses and other perks, allowing you to test some of their games for free, which leads us to our next tip.

    Differences Between Payline Slots and Reel Slots?

    Reels are the vertical columns that spin when you hit the spin button and suggest the slot’s layout. So a game with 3 or 5 columns is known as a 3-reel or 5-reel slot. Paylines, however, indicate whether you have 1, 10, 20, 50, 100 or more chances to win per spin.

    Are More Paylines Better in Slots?

    It depends on your budget and the max payout a slot can offer. Playing games with fewer payouts can stretch your budget to last longer, but generally speaking, more paylines can provide more ways to win and more bonus rounds leading to more fun.

    Real Wins vs. False Wins at Slot Machines

    False wins make you feel like you’ve won despite losing cash. Whenever you land a win that’s less than what you bet per spin, it’s considered a false win.

    How Does a Slot Machine Payout?

    The great thing about online slot machines is that they’re programmed to payout automatically in real cash to your casino account at the end of your gaming session.
