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

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.

Common Features of Real Money Slot Games Online

While every game is different, most online slots follow a similar structure. There are basic symbols that award money based on the paytable and there are usually some sort of special symbols that unlock bonus rounds or free spins. Here are the top features to look for.

Scatter Symbols

Function: Unlock bonus rounds, free spins, and mini-games.

Tip: Look for a set number of scatters to activate these special features.

Multipliers

Function: Amplify your winnings.

Example: A 5x multiplier turns a $10 prize into a $50 win.

Wild Symbols

Function: Substitute for other symbols to complete winning combinations.

Note: Wilds usually can’t replace scatter symbols.

Free Spins

Function: Award you with additional spins without extra cost.

Tip: Accumulate scatters or trigger special features to activate free spins.

Mini Games

Function: These are extra games to win prizes. Just like a “Spin the Wheel” situation.

Tip: Landing on certain segments can lead to bigger rewards or even jackpots.

Cascading Reels

Function: Symbols from winning combinations disappear, allowing new symbols and potential additional wins.

Note: This feature can lead to consecutive wins from a single spin.

Top Online Slot Game Developers

Navigating the world of online slots can be overwhelming with the multitude of game developers out there.

To help you understand the landscape better, here is some information about the leading real money slot game developers, highlighting their offerings and backgrounds.

Real Money Slots vs. Free Games and Demos

Many online casinos offer free demos and practice play, which gives you valuable information, like how to activate the bonus features, what the symbols look like, and exactly how payouts work when you win.

While free games have their perks, they also have some downsides. Let’s compare the pros and cons of each gameplay style.

Tips and Strategies for Playing Online Slots

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.

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.

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?

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.

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.
