How to Decide on the Best Online Slots Site for You

These tips can help you decide which online slot casinos are the best for you.

Consider What Type of Online Slots You Want to Play

Do you want to play online casino slot games for real money, are you looking for free demo slots, or do you prefer slot tournaments? Several of our recommended online slot casinos offer both real money wagering and free demo play. For slots tournaments, check out Super Slots, Wild Casino, and SlotsandCasino.

Consider What Banking Methods You Prefer

Crypto payments provide anonymity and are the fastest payout online casino method, while credit cards are always popular choices among players. Las Atlantis offers both credit card and cryptocurrency deposits and payouts.

Consider Your Bankroll

All our recommended slot casinos have low bet minimums, and most minimum deposits fall in the range of $10–$50. However, if you have a larger bankroll, you should consider using a site like DuckyLuck that rewards players who make frequent or large deposits through its DuckyBucks and Crypto Elite loyalty programs.

Consider the Type of Player You Are

Do you want to play slots with a high probability of payout, or do you want to chase a jackpot on a slot with lower payout odds? If you prefer high probabilities of payouts, SlotsandCasino has a large selection of classic-style slots, while Bovada is a great choice for progressive jackpot slots.

Features of Online Casino Slots Games

Online slot games have an array of diverse features. Here are some special features often found in slot games.

Progressive Jackpots & Hot Drop Jackpots

Progressive jackpots take a small portion of each player’s wagers and put them toward the pot. These jackpots build until someone wins, which is why they frequently reach six-figure prizes. Hot Drop Jackpots are progressive jackpots with guaranteed payouts every hour, every day, and one that can drop randomly at any time.

Reels & Paylines

Slot reels are the spinning mechanism that the game’s symbols are placed on in most slots. The most common set of reels and symbols in slot games are 3×3 or 5×3. Paylines are the lines or patterns that crisscross the reels and indicate where the symbols must land to generate a win. Note that some video slots have game mechanics without reels or even paylines.

Wilds Symbols

Wilds symbols are icons in slot games that can substitute for other symbols in the game, and therefore help you win. Many online slots have wilds with extra features, making them multiply your winnings, expand to cover more symbols, or even walk or fall. The sticky wilds that offer re-spins in the game are also a players’ favorite version of a wild symbol.

Scatter Symbols

Scatters are symbols in a slot game that are not dependent on a payline. Wins from scatter symbols don’t depend on where the symbols land — they’re scattered! Often, a scatter is used as a bonus symbol that can trigger a free spins bonus game, a pick-and-click bonus, or any other special bonus the game offers.


A multiplier in a slot game is a special feature that multiplies your winnings by a certain number, like 2x, 3x, or 25x. Multipliers are typically connected to another symbol, such as a wild symbol. Or, they can be rewarded randomly in a game round. Multipliers are also commonly found within the bonus game in a slot, such as a free spins bonus.

Tips for Playing Online Slots

Keep these top online slot tips in mind to get the maximum benefit from playing slot games. 

Use Bonuses & Promotions

When playing slots, online casino bonuses can go a long way to extend your bankroll and playtime. For example, welcome bonuses often match a percentage of your deposit, and some include slot games with free spins.

Another way you get the maximum benefit from slot games is through slot tournaments with low buy-ins and big prizes. Loyalty programs that award slot play can also work to your advantage with perks like free spins, matching deposit bonuses, and cashing out comp points.

Understand Return to Player Percentage, Volatility & Variance

RTP represents the average percentage of money that a slot game returns as winnings over a long period of play. Games with a high RTP have better long-term odds, and games with a low RTP have lower payout odds.

Volatility and variance refer to the frequency and size of payouts in slot games. Low variance slots are low risk because they offer small but frequent wins. On the other hand, high slot variance means you can expect infrequent but large wins.

Ignore Myths About Hot Games & Timing Your Bets

Online slot games use random number generators (RNGs), which are software-generated algorithms that ensure game outcomes are both random and fair. The idea that a slot game is about to “hit” or is “hot” is a myth, as all game results are completely random.

The timing of your bet does not affect your odds of winning. Slot games are purely games of chance, and there are no strategies or methods to predict or improve your chances of winning.

Play Games by a Variety of Developers

When you play slot games by a variety of trusted software developers, you’re treated to a world of diverse slot themes and storylines. You also find unique in-game features like free spins, multipliers, wilds, and bonus games.

Each developer has a unique style, so trying several is a great way to explore various types of slots. For example, SlotsandCasino uses nine developers, and they are categorized, so you can easily find games from different developers.

Free Online Slots Options

Most of our recommended online slot casinos offer slots with a free-play or practice mode where you play using a fake money balance. This allows you to test various slots and familiarize yourself with the game before you make a real money wager.

Playing online slots for free is especially useful if you want to try out a new slot, but it can also be a great option when you want some free entertainment. Try these popular slot titles for free.

Here are a few tips to help you keep things in check:

  • Before you start playing, decide on how much money you want to play for, and for how long you want to play — stick to your decision

  • Manage your slot game wagering by setting limits on your casino account — most casinos offer a deposit, loss, wager, and session limit

  • Never chase your losses, and never play for money you can’t afford to lose — when gambling is no longer fun, it’s time to stop
