Tips for playing real money Slots Online

Slots are games of chance, operating through Random Number Generators (RNG). This means there is no strategy that guarantees wins when playing slots. However, there are some tips to keep in mind when playing online slot games.

Check the RTP Check the RTP

The RTP (return-to-player percentage) of a slot means the average amount won when playing the game.

For example, a slot with a 97% RTP will pay out an average of $0.97 per $1 bet. This is an average, not a guarantee, but does mean a slot with a higher RTP is slightly more likely to pay out.

Use all the paylines Use all the paylines

Some slots provide variable paylines. This means you can select the number of paylines active when you play. While less paylines is cheaper, it also shuts down some of the way to wins. Always bet the maximum number of paylines if you can afford to or play a fixed payline slot.

Keep to your budget Keep to your budget

While betting higher amounts can make wins more likely, it does not guarantee wins. Have a budget in mind before you start playing, and whether you reach that budget in 200 small value spins, or 10 high value spins, make sure you stop. Never bet money you can't afford to lose.

Stick to the best Stick to the best

The highest profile software developers have the reputations they do for a reason. Not only are the games from these developers the highest quality in terms of bonuses and graphics, they are also known to be safe, secure, and fair.

Free play first Free play first

If you're considering trying a new slot, see if you can find a free version of it before making your first real money bet. This gives you a chance to try the slot out and practice some strategies before moving on to real money play.

Bonus Rounds Bonus Rounds

Always keep an eye out for tempting bonus rounds whilst playing. Some online slots games have hidden bonus features, so you could get lucky and stumble across free spins, jackpots, multipliers, or cash prizes.

Sweepstakes Casinos

Sweepstakes Casinos adapt old sweepstakes laws which allow for real money slot play online. This is done by allowing players to spin the reels of slots using virtual currencies, which is purchased with real money. These online casinos started back in 2005 and have been growing in popularity ever since.

FAQs

How do online slots work?

You just need to spin the reels and then see which symbols come up. If you get a winning combination of symbols, you'll be given a prize. Some slots also have bonus features, such as free spins, which are loads of fun and can lead to some big prizes.

What is a progressive jackpot?

Which online slots pay out the most?

When it comes to the slot with the biggest jackpot, it's almost always Mega Moolah. This is the world's most popular progressive slot and regularly offers a jackpot worth over $10 million.
