How to Choose The Best Online Slots Sites

When you are looking for the perfect betting sites with slot games, there are certain considerations that you need to think about before depositing at a site. Two of the most prominent issues are online safety and fairness of play, which we explore in more detail below.

Are Online Slots Fair?

Online slot games, like most casino games, come with an advantage applied to the house, known in the game as house edge. Despite this, players will almost certainly pick up a winning spin or two regularly over five or so spins. This is because casino games employ Random Number Generators (RNGs) to ensure every spin is random and has the same chances of success as each of your other spins, future or past. At the end of the day, slots are games of chance, and a casino will not benefit from any short-term, one-off success enjoyed over players. Instead, online casinos will do much better long-term by encouraging repeat business and making a wider profit. Rigging games would not only lead to customers avoiding their casino site but also alert the relevant authorities.

Are Online Slots Safe?

The question of whether or not the slot game you are playing is safe very much depends on where you are playing it. By ensuring that you choose to deposit and play at an online casino that is fully licensed by the appropriate gaming authority, you should not have any issues to worry about. If the casino is licensed, then it will be utilising all of the very latest security protocols and procedures to ensure that it is safe for all of its players.

 

Why Play Slots Online?

There are a whole host of reasons that people love to play on slots betting sites, but perhaps the most important point to note is that there is next-to-no skill needed to get started playing. Online slots, which can be played anytime, anywhere, also provide endless hours of entertainment, come with brilliant and exciting themes and, critically, come with massive jackpot potential, especially if you are playing progressive jackpots games.

 

How to Play Online Slots

While there are many different types of slots, they all really work in pretty much the same way. This is to say that all slots have reels with symbols on that spin downwards on the grid. Where the symbols land in relation to each other on each spin is what dictates what players will win.

In modern-day online slots, there are many different ways these games can play or payout, and they each come with a range of bonus features. While some are played on three reels, others have five reels; but, at the end of the day, all slots are about the forming of winning combinations.

 

Online Slot Types

There are more than one type of online slots to try and, while they all work in the same basic way, there are a few differences that need to be understood.

Video Slots

Video slots are a great way of showing slot games through the screen. Video slots allow for a far greater range of themes, create extra paylines, allow for added bonuses, side games and features that will keep users of all types entertained.

Progressive Jackpot Slots

Progressive jackpot slots are games that are all connected to a wider jackpot which grows every time a relevant game is played, and the jackpot is not won.

Classic Slots

Classic slots are played with three spinning reels, or bars, that contain all of the old original symbols, such as bells and fruit, hence in the UK they can commonly be called fruit machines.

 

Online Slots Terminology

While it is true that these games are incredibly easy, newcomers to online slots might still be unfamiliar with some of the terminology. What follows should help with this.

Symbols

Most games will employ 10-12 symbols which have differing paying levels. Generally, there will be low paying symbols plus higher paying ones that relate to the theme of the slot.

Reels

The reels run vertically down the grid and include the symbols on them.

Cascading Reels

Every time a win happens in cascading slot games, the symbols that made the win are removed from the game and replaced by new ones that cascade down.

Wild

A wild is a symbol with special abilities that allow it to substitute for all other symbols and make winning combinations.

Scatter

Scatter symbols do not require a payline connection to activate wins and bonus features.

Paylines

Paylines connect the combinations and can zigzag all over the grid, pay left to right, right to left and even sometimes both ways.

RTP

RTP means Return To Player, and refers to the game's payout percentage. The bigger the figure, the better it is for the player.

Progressive jackpots

Progressive jackpots are a shared prize pool that is made up of slices of all of the bets that contributed to it. It will keep swelling until someone scoops the lot.

Bonuses

Often, slots will come with bonus features which can sometimes be a great way to boost winnings.

Jackpots

Jackpots are the maximum amount that can be won playing online slots.

Bet Level

Bet level is the stake that you bet per spin.

RNG

RNG stands for Random Number Generator and ensures the randomness of spins to keep payouts fair and regular.

Slot Software

The software behind the game you are playing. Since the explosion in popularity of online casinos, a saturated market of gaming providers has sprung up each looking to out invent the other. Consequently, today we have many format tweaks around slots games.

 

Best Slots Betting FAQS

🏆 When do Online Slots Pay Out?

Online slots pay out when players achieve and form combinations by lining up winning symbols.

🔢 What Are Paylines Then?

A payline is what connects those same symbols to make the combination.

📍 But, Are Online Slots Fair?

Yes, you don’t have to worry about that – all regulated online slot machines are completely random, thanks to the RNG which keeps things fair.

🎰 How do Online Slot Games Work Exactly Then?

All players need to do is hit the spin button and hope for the best – that’s the basics of how these games work.

💳 No Strategy Needed Then?

No, not at all.
