Slots Pay Out FAQs: Did you know this about Slot Machines?

In this section we’ll be covering some final questions you might have in relation to the best payout slots, which should be a great section for new players for obvious reasons. With this knowledge you should be able to navigate sites like Easy Slots with the greatest of ease. We hope you take something away from this section.

Can I win real money with free spins?

Yes, you can win real money through free spins. Free spins in general in any slot you play are always worth chasing as they often come with multipliers attached. In other words: netting real money can be fast-tracked through free spins, almost exclusively. We should mention that any bonus spins played through a promotion are subject to wagering requirements.

Wagering requirements are important to know as bonus funds are separate to standard winnings. These terms and conditions will dictate when it’s possible to cash out any wins accumulated through casino bonuses. Wagering requirements also let you know when your winnings must be used within, in terms of time, before they expire too. Just remember to please gamble responsibly no matter what you play.

What should I check in a slot game?

Max bet and bonus features should be the main thing you check in a slot game. Any min deposit 20 max or deposit 20 max bonus slot you come across is normally worthwhile. Always look at return to player percentages and any wagering requirements are present too — only if this slot is part of an active welcome bonus.

New customers, be sure to check out how many ways to win there are in every slot you play. We say this because new players should probably stick to online slots that are relatively easy to get the hang of. A fruit slot for example is a good starting point. Once you’ve established confidence in slot games, you should then move up to the higher payline/variance slots.

Which are the best online casinos?

As stated, the best online casinos are those that offer a diverse list of online slot games and unique welcome bonuses/standard promotions. Easy Slots is a great start, but we aren’t ruling out others. Be sure to check out user reviews of the so-called ‘best casino sites’, as they tend to provide a clearer picture on any given online casino where you can win real money.

We find that any site with a rewarding VIP levelling system is worthy of your time and your money. Some of the best payouts will come through bonuses provided by this system. All you need to do to hit max rank is to simply play certain online slot machines too — it’s a perfect incentive to earn bonus funds!

What is the house edge in slots?

Every online casino site you come across will have a house edge present in all casino games. Like the house edge you might find in land casinos, so too does online casinos offering the digitised version. You’ll find that the house edge differs depending on the online slot, or online casino game, you’re playing. This is a purposeful decision, as strategies and other factors can increase/decrease your chances of victory.

The house edge is otherwise known as the ‘hold’ of the game. Every pay table and bonus feature you come across have been carefully considered by a mathematician when working out the house edge. One of the largest misconceptions is that reels lockout to protect the house edge, which just isn’t true, and would be considered highly illegal.

What is the best RTP in online slots?

We’ve mentioned RTP, which stands for return to player, quite a lot already. The return to player percentage determines how much money you get at the result of a pay out. Most new players believe that 100% of their winnings come back to them. No, in online casino games a small cut goes elsewhere, which is why it is important you always play the games that benefit you and you alone.

As a rule of thumb we’d always recommend playing online slot games with a RTP of 95% RTP or higher — or if you’re really dedicated: a RTP of 97% or higher. High variance games/progressive jackpot games are a hell of a lot more rewarding (literally) when you get a bigger piece of the pie once those reels stop spinning. Find a high RTP game and you’re guaranteeing more cash for yourself!
