When you open any online casino lobby, it’s not uncommon to come across hundreds of slots. You may ask yourself what differentiates them and what makes each one “tick”. Between most video slot online, the differences are negligible, but there are cases of rather diverse slot machines that can easily trap the inexperienced player.

When we say that, we refer to progressive jackpots and slots that require a bigger time and money investment in hopes of a return.

Dubbed as one of the best slots for wagering purposes, Break da Bank Again is a refreshment of its 3 reeled predecessor, Break da Bank.

Moreover, Dazzle Me boasts a number of special features; Dazzling Wild Reels – which appear on random reels acting as Wild symbols, Free Spins (8 to 16) and Linked Reels – a feature that only appears during free spins.

Gonzo's Quest slot online UK

Gonzo’s Quest

When we talk about Gonzo’s Quest, we’re talking about a NetEnt flagship product. This video slot has nothing but praise amongst casino players worldwide. While some NetEnt products have come to disappoint over the years, some have proven to be pure gold – such is the case of Gonzo. This NetEnt creation shakes up the foundations of video slots, by replacing the reel feature with an avalanche feature. As the symbols are set in place after a spin, they will be replaced by more falling symbols, increasing your chances of a winning combination as well as your multiplier. A bonus game is the only thing lacking in Gonzo’s Quest, but free spins are in place to match your gusto.

This is why we’ve handpicked the best video slots tailored to your needs in terms of winning potential.

Although you may come across video slots that can potentially pay more, our choice was formulated by taking the frequency of wins and RTP as detrimental factors.

Best slot online machines to win on online

Blood Suckers

The number one on our list – Blood Suckers, is the highest paying NetEnt slot. It has a Return to Player of 98%! In fact, because of its high return, most casinos will only allow 50% game contribution when wagering your bonus on this slot machine. Blood Suckers will not only prove rewarding via normal play, but it also features a free spins round and a bonus game.

The 10 free spins round is initiated by 3 more Scatters (vampire bride symbol) on your reels, as per usual. In the free spins game, all winnings are multiplied by x3. The bonus game on the other hand, is activated by 3 or more bloody hammer symbols. In the bonus game, you must click on coffins and stake vampires, until you come across an empty coffin – which signifies the end of the bonus game.

Super Monopoly Money

Just like monopoly itself can turn you into an owner multiple buildings, businesses and what have you, so can this slot fill your pockets in similar fashion, albeit on a smaller scale.

Super Monopoly Money is renowned for its special bonus features. WMS have obviously done a fantastic job at constructing a slot that offers a fine balance between entertainment and winnings.

Free Spins

Let’s start with the free spins. As you may have assumed by now, 3 or more Bonus or MM Bonus symbols trigger 8, 10 or 15 free spins. The difference between the symbols lies in the fact that spins activated via the MM Bonus symbols will transfer your winnings into monopoly money. No worries, they are still yours but with a side benefit, you have an option of spinning the wheel bonus.

Wheel Bonus

The wheel bonus is part of a special feature exclusive to this slot machine. As we already explained, the MM Bonus gives you monopoly money, which enables you to spin the wheel bonus for a chance of multiplying your stake up to x200. Another bonus symbol is the MM Wild. It can appear on reel 5 and multiply your win, effectively turning it into monopoly money.

Monopoly money can be accumulated, and you can spin the wheel bonus any time you want, but there is a max limit of monopoly money in place.

Free Parking

The free parking symbols take part of yet another feature that is unique to this game. When these symbols appear on your reels, you can choose between 5 unrevealed symbols. When the symbol is revealed, it will replace your free parking symbols and combine with the rest of the symbols, heavily enhancing your chance of winning.

Last but not least, a jackpot win is possible by lining up five jackpot symbols adjacently on your reels. As you can see, Super Monopoly Money can shower you with bonuses all night long. To truly see how it all plays out, you will have to try it out yourself by playing for fun or real money.

Thunderstruck slot

Thunderstruck II

Thunderstruck II is an iconic Microgaming creation. It is based on famous mythology figures in the likes of Thor, Odin and Loki. They are all beautifully intertwined in a marvelous slot that will dazzle you with its graphics and carry you through turbulent waters by its soothing soundtrack.

Food for the eyes – perhaps, but what makes this slot deserving of a mention here?
The answer is simple: bonuses. 3 more or more bonus symbols in Thunderstruck II activate The Great Hall of Spins. The hall contains four bonus games; Valkyrie, Loki, Odin and Thor. Valkyrie is always available, but to play the rest you will need to activate the bonus game 5, 10 and 25 times, respectively.

Valkyrie grants 10 free spins with an x5 multiplier. Loki awards 15 free spins with a Wild Magic symbol. Odin grants 20 free spins with a Wild Raven bonus feature and an x6 multiplier, and lastly – Thor will bestow you with 25 free spins with a Rolling Reels feature and an up to x5 multiplier.
All bonus games can be retriggered except for Thor’s.

A wildcard feature called Wildstorm can randomly appear on your reels, transforming up to 5 symbols into wilds. While we’re at it, the wild symbol in this game is the Thunderstruck II logo. It substitutes for all symbols except for the bonus symbol.

Immortal Romance

We’ll admit that Immortal Romance doesn’t quite fit the bill on this list. The game is actually not so recommended for inexperienced players. If you’re past that phase though, you should know that on a good day this slot machine can boost your bankroll like no other. It’s the reason we mentioned it in the first place. What the game does require is a reasonable deposit to start with, and a bit of patience. The special features of Immortal Romance are infrequent, but when they do pop up the multipliers are potentially huge.

Slot machine tips

The number one tip we would give to players when playing slots, is to pick the highest paying slot machine. We’ve already listed a number of online slots boasting a high RTP and bonus rounds. What we can offer you now is gameplay tips to handle yourself better and maximize profits.

Make sure to understand the slot you’re playing. Read through its information quickly before diving in, or read a review online. One way or the other, you need to get acquainted with the game before you play it. Of course, checking out the RTP falls under this advice.

One thing you should also look to do before playing is plan your bankroll. Slots are highly entertaining with the right mindset, and you will want that entertainment to last a while. With a small budget, look towards minimum bet, and vice versa. Tread carefully though, as some slots accept hundreds of pounds per spin.

Don’t chase losses. This applies to any casino game really. Betting big after a streak of losses is the most common and most devastating impulsive reaction players will resort to. Don’t make this mistake as it may cost you dearly, and we don’t want that to happen.

Bet on max paylines. This means that with modern video slots – paylines matter. If you can’t select to play on all paylines (usually 25) you are potentially missing out on bonus rounds or symbols. At the cost of reducing the coin size, 25 paylines can cost you a small amount of £0.25 per spin. It’s better to go that route instead of selecting 10 paylines with a higher coin size.

These general tips are common sense to the experienced player, and you should keep them in mind before playing any slot online.
