    How to Start Playing Online Slots

    If you’re ready to get started, follow this step-by-step guide, and you’ll be playing online slots for real money in no time.

    1. Choose a Trusted Casino

      Start by selecting a reputable online casino with slots. If they have a welcome bonus with free spins, it’s a plus. However, if you decide to claim a bonus, please do not forget to review the terms and conditions.
    2. Fund Your Account

      You can play game demos until the cows come home, but you’ll need to deposit funds into your account if you decide to play for real money. Find the casino’s cashier page and make at least the minimum deposit, which is typically around $20.
    3. Pick an Online Slot Game

      Head to the slots section of the site. Look for slots with a high RTP and consider the volatility or jackpot potential (like the ones on this page). You might prefer penny slots if you are starting. If unsure, check the guide to find slots by type on this page (bonus buy, crypto, penny, and so on). Click on the logo to open the game.
    4. Read Through the Game’s Instructions

      Each game has different symbols and ways to activate the bonus features. Read the rules, learn about the features, and go through the symbol paytable so you know exactly how to play.
    5. Choose Your Bet Amount

      Your bet depends on the coin denomination and the number of paylines you play. Adjust the wagering settings using the game’s buttons to set the amount per spin you want to spend.
    6. Spin the Reels & Have Fun

      Click the spin button (usually the largest one) to spin the reels. Where the symbols stop determines which winning combinations you hit and your payouts. Don’t forget to take breaks, watch your bankroll, and have fun.

    Responsible Gambling Disclosure

    Responsible Gambling Icon

    Set reasonable limits for yourself, and only play for real money when you can afford it.

    Real money slot games require discipline and sometimes restraint. Take heed to the responsible gambling advice set out by every top online casino.

    Use tools such as clocks on the display of many slots games and the win/loss limits you can set with some titles.

    The Highest Paying Online Slot Games

    High RTP slots are the most sought-after games. That’s because, for every dollar you put in, you’re more likely to get some of that money back.

    Regardless of the theme, layouts, or bonus features, the return to player percentage indicates which titles pay out the most. The higher the number, the more money the machine spits out over time.

    Tips and Strategies to Play Better and Win More Often

    Aside from the RTP, many things can affect how lucrative an online slot game can be at the end of the day. If you want to increase your chances of winning at online slot games, keep the following advice in mind.

    Online slots odds and rtp

    Slow Down Your Gameplay

    With auto spin features and only needing to move a finger over to the mouse, it’s easy to play online slots really fast.

    To have an enjoyable session, I’d recommend that you slow down a bit, set time limits, and take breaks. It will not only extend your bankroll but also help you get more entertainment between deposits.

    Online slots volatility

    Consider Slot Volatility

    The volatility of a slot lets you know the risk that’s baked into the game. A low volatility slot pays out more frequent smaller wins, while a high volatility game will pay more money less often.

    Consider what works best for you. Do you prefer to take chances or play on the safe side?

    High Money Bets Banner

    Bet for Your Bankroll

    If you sit down at a machine with $20, you’ll want to set a low enough bet per spin that you can make it through strings of losses without draining your account.

    The general rules of bankroll management say you should set a bet that gives you between 100-200 spins for a session.

    slot machine 5 reel slots banner

    Play to Hit Bonus Rounds

    Every game has a main objective, and when you’re playing slots, that is to hit a bonus round. Whether it’s free spins, sticky wilds, or a cascading mega bonus, these features pay the big bucks.

    Hitting some bonus rounds can take 20, 50, or even 100+ spins. Another reason it’s important to set a bet that fits your bankroll.
