What is Return to Player (RTP) with online slots?

No matter where you play your favorite online slots, you’ll see a percentage next to every game. Return to Player is the average percentage that an online slot will pay back to players over time.

For example, an online with an RTP of 97% will, on average, yield back $97 for every $100 spent. This does not guarantee that your spins will return 97%, however. These simulations are run thousands of times to determine that percentage. In theory, higher RTPs will return more to players over time, but individual plays are such a small sample size that results will vary. The majority of online slots are between 94% and 98%, so there isn’t a ton of variance to begin with–but is something players should take into account when determining which online slots they want to play.

Choosing the right volatility

Volatility is a tricky feature to online slots that players will want to take into account before playing. It measures the risk associated with each game, with lower volatility delivering smaller, more frequent wins, while higher volatility offers more chances to win big but at a less frequent rate. There’s no right or wrong volatility for games, and the top sweepstakes casinos and social casinos offer hundreds of games in each category. Players will need to determine how much they’re willing to risk to go big with games. The top operators list the volatility attached to each game, so you’ll know expectations associated with the games before you begin playing.

Types of Features at Top Online Slots Sites

Within the different online slots available to players, you’ll find a handful of features that enhance gameplay and increase your chances for success. Here’s a general look at the different ones you may find during your experience:

• Free spins: Just about every online slot gives the potential for free spins, where you’re able to spin reels at no cost to you. These pay out the same as traditional spins and can be earned through welcome offers, hitting specific symbols on wagered spins, and more. Free spins can also unlock different multipliers and play features, too.
• Wild symbols: Certain online slots will drop wild symbols into reels that offer up more winning combinations to players. Some slots have expanding wilds that cover multiple reels, others have sticky wilds that remain on reels through multiple spins, and others create higher payouts for players.
• Cascading reels: Certain online slots have a feature called cascading reels (or tumbling reels) where winning characters fall off the board and are replaced by new ones, giving players the potential to earn additional winnings on the same spin. Some offerings have multipliers with each cascade, adding to the fun (and winnings).
• Bonus buy: Players will have the chance at certain online slots to buy their way into bonus rounds or free spins instead of trying to trigger it through regular gameplay. You’ll need to decide.
• Hold and win: Players who land special symbols on their spins can lock them into place for additional spins on hold-and-win online slot games. Collecting additional special symbols can unlock multipliers and bonus rounds
