Online Slot Machine Basics

Little to no skill is needed to play slots at the top online casinos. Let us guide you through the basics of slot machine play.

How to Play Online Slot Machines

Online slots are played on a series of vertical reels filled with symbols. In every game, the reels spin and randomly come to a stop thanks to a random number generator (RNG) that is regularly audited to ensure fairness. You win money by lining up matching symbols on paylines that run horizontally across the reels (though a few games have vertical or diagonal paylines, too).

First, you need to select your coin size and the number of paylines you want to bet on. Some slots have fixed paylines where you will have to bet on every possible combination.

Online Slot Bonus Features & Rounds

Most modern online slot machines feature a bonus round. The bonus can be triggered at random or by landing the required number of scatter symbols. These are symbols that payout regardless of where they land on the reels. Common slot bonuses include:

Free Spins: You receive a number of free games, sometimes with a prize multiplier attached
Prize Wheel: You win a spin of a prize wheel that contains free spins, multipliers or jackpot cash sums.
Wilds: Wilds are joker symbols that help complete a winning combination across the reels. Wilds sometimes have prize multipliers attached.
Cascading Reels/Re-spins: In a slot with cascading reels, winning symbols are removed from play, allowing symbols sitting above on the reels to fall into their place. You then receive a free reel re-spin. Consecutive winning cascades are usually awarded with a progressive multiplier.
Pick ‘em Bonus: In a pick ‘em bonus, you get to choose from 10-12 hidden symbols on the screen. Behind each symbol is a cash prize, free spins or multiplier. Keep choosing symbols until the “Collect” sign appears.

Online Slot Strategies to Consider

Online video slots are simple to learn and play. But how can you make the most of your gambling bankroll? Follow our five easy tips.

1. Choose the Highest RTP

Every slot has a theoretical RTP built into the game. Always check the paytable first to see what the average payout is. The higher the RTP, the better the long-term payouts and the better your chances to win.

2. Choose a Game You Enjoy

There are thousands of online slot machines to choose from. It’s important to select a slot that you won’t get bored of. Choose a game with an interesting theme or characters, and make sure you care about the bonus features.
