More about slot machines

Casino slot machines are fun to play online and offer many special casino features and enticing gameplay. The best online slots offer a fair chance of winning and provide loads of entertainment and betting action.

When choosing slots online, the first thing to consider is whether to play free slots or real money slots. Next, select a theme that appeals to you and finally, a slot machine that suits your budget. Many online slots offer a wide range of betting options and pay lines. The fewer the pay lines, the better for your bankroll as you can bet on all the pay lines and activate all the features with less money. A slot with 30 pay lines will cost more than one with only 9. Generally, betting on all the pay lines activate the bonus features and a progressive jackpot. With so many coin sizes to choose from, you can always find a bet that fits your budget.

What are bonus features in slot games?

The most popular slot features include free spins, bonus rounds and special symbols like Scatters and Wilds. The Scatter usually triggers free spins or the bonus game. Wild symbols replace others to create winnings on your pay lines. They all contribute to the enjoyment and serve up extra chances to win. Some games have cascading reels, sticky wilds and expanding wilds. Newer slot releases are breaking the boundaries and treading new ground with original features never seen before and new setup and structures.

What is the layout and design of a slot machine?

Online casino slot machines are centred around the reels and pay lines where the bets are set. The symbols appear on the reels after every spin and getting two or more identical symbols pays out a prize. Slot symbols typically pay out from left to right except for the Scatter. Slots pay out according to their return to player (RTP) percentages. The best online slots tend to pay out between 95% and 98%. That percentage represents the amount you can expect to get back from the game if you play for an extended time. The RTP will determine your eventual payback, so the higher it is, the better.

With so much to consider, choosing the right slot is no easy task! New slots with innovative features are appearing, and styles and designs are evolving too. The theme is a matter of personal preference, and there are numerous mobile slots, especially optimised, to work on tablets and smartphones.

Discover new slots every day

There are new casino slots released regularly and in abundance. All you have to do is choose one that tickles your fancy. Perhaps a traditional one-armed bandit slot machine, or an atmospheric Ancient Egyptian themed slot. You might want to go for the huge prize progressive jackpot, or discover a cascading reels slot. With such a choice of new slots coming online, the future beckons and slot fans have a lot to look forward to.

Classic retro games or new slots?

Classic 3-reel slots are as popular today as when they first appeared at land casinos. Vintage style online slots are available at all online casinos due to their high payout potential and high demand. These slots use retro symbols like fruits, bells and bars and the style is akin to traditional slot machines. You might prefer a more adventurous slot game with 5-reels, or more and exciting bonuses and free spins. These slots contain bonus rounds, multiple stages and a storyline. There are many new real money slots you can try, and playing the free slots first prepares you when betting real money later.
