Online Slot Machine Basics

Little to no skill is needed to play slots. 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.

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.  

3. Test the Volatility with Demo Play

Some slots will have a low hit rate. That’s the frequency with which a game pays a prize. Volatile slots might decimate your bankroll before awarding a big prize. Test these games out with play credits first to see whether they have high or low variance by playing free online slots.  

4. Increase Your Stakes for a Progressive Jackpot

Progressive slots award a big jackpot at random or through a special bonus game. But progressives will usually award big prizes to players who pay the highest stakes. Try increasing your coin size and take a shot. 

5. Claim Your Casino Free Spins

The best US gambling sites will award free spins to new signups. As a regular player, you can also claim bonus spins on a Slot of the Week. Take advantage of these bonus promotions when you play online slots for real money.
