10. Sweet Bonanza

Starting our list at number 10 is Sweet Bonanza by Pragmatic Play. With its free spins, tumbling reels feature, scatters and multipliers, Candy Land is no longer just a place for those with a sweet tooth. 

Sweet Bonanza will also appeal to low and high-rollers alike with its Ante Bet feature, where you can adjust your bet and volatility level in the bonus games.

Whether you like to play it safe or take huge risks, this is one of the best slot games to get you some sweet payouts with the possibility to win 21,175x your stake. At the max bet of 100 credits, that means winning over a cool 2 million.

9. Gonzo’s Quest Megaways

No top 10 slots list would be complete without a megaways slot on it, and what a slot has Red Tiger given us! Gonzo’s Quest Megaways is not only packed with action and adventure, but thanks to the Megaways mechanics, you also have 117,649 ways to win

Moreover, it still comes with free spins, wilds, bonus rounds, and the Avalanche Multiplier feature which means that your winnings can multiply by up to 5x in the base game. 

The RTP might seem a little on the low side at 94.66%, but with the potential of earning up to 21,000x your bet and the wide variety of features, you’re more than likely to come away with some amazing rewards.

As veterans of the game might have noticed from the name, Gonzo’s Quest Megaways is the Megaways version of the much-loved Gonzo’s Quest, but with a few touch-ups that have taken the game to a whole new level. 

Whether you’re new to the game or not, we highly recommend checking it out at any of our video slots.

8. Primate King

Red Tiger welcomes you to Skull Island, a mysterious island with an ape-shaped cave, skulls, and bones. Expect to see snakes, treasure chests, maps, and compasses as high-paying symbols, with the gorilla as a wild symbol.

The gorilla is especially exciting because apart from substituting any other symbol to form a win, it can also smash low-paying symbols away. On this Primate Smash bonus, higher-value symbols will drop to fill the remaining gaps, guaranteeing a win from the new mix of symbols.

Head over to the best Red Tiger online casinos to meet the Primate King and claim the biggest welcome bonus offers when you sign up.

7. Legacy of Dead

Coming in at number 7 is Play’n GO’s Legacy of Dead, forming part of a series of ancient Egyptian-themed slots by the developer. Typical of the best slot games, Legacy of Dead comes with stunning visuals, taking you to an Egyptian temple. Here, you’ll meet Isis the bird, Anubis the dog, a golden statue, and a pharaoh with golden eyes.

A golden burial chamber doubles as both a wild and a scatter symbol, where with the power of the latter, it can trigger a free spins bonus round, also multiplying your stake. Sealing its place on our list, the Legacy of Dead slot has also managed to elevate the wild and expanding symbols features. 

Trigger the free games with more golden burial chambers and a second symbol will expand next to the first. This can lead to triggering the games over and over again, with all 9 symbols expanding, giving you several payouts in each free spin.

6. Big Bass Bonanza

Take a deep dive into Big Bass Bonanza and get ready to get some awesome wins on this 5-reel, 10-payline slot from Pragmatic Play. The base game is simple yet fun, but keep an eye out for the bass symbol as this is where the big catch lies!

Land 3, 4, or 5 bass on a hook symbols and unlock 10, 15 or 20 free games. During the free spins round, a fisherman will act as a wild symbol and he can help you complete a combination. Collecting 4 fishermen will also get you an additional 10 free spins, with fish Money Collect symbols paying double the base level. 

The game doesn’t end there, though. Collect 4 more fisherman symbols and the round starts again, with the fish symbols now paying triple. The round can even be repeated a 4th time, with a whopping 10x multiplier for all fish symbols! Go fishing and angle a huge win at one of our top-ranked online casinos.

Helping you hit massive wins is the Avalanche feature, where multiple wins can be triggered in the same spin, while with the Free Fall bonus feature, 3 or more sparkling golden tiles can trigger up to 10 free falls. The wild symbol also boosts your chances of hitting it big.

This 5-reel slot includes an array of bonus features such as stacked wilds, free spins, mega symbols, and the Money Respin feature to increase your chances of winning bigger prizes. Earning its place among the best slot games, Wolf Gold also has a jackpot that offers Mini, Major, or Mega prizes, giving all players a shot at winning up to a whopping 250,000.

3. Bonanza

Bonanza by Big Time Gaming just had to be in our top three as this is the original slot game that started the Megaways frenzy. The Megaways mechanics took the virtual slot world by storm with its unusual layout of the grid, cascading reels, and the massive ways to win.

The scatter symbol can also spell out the word G-O-L-D across the reels, giving you 12 free spins. The free spins bonus round comes with a multiplier meter that will continue accumulating the more you play since there is no limit on the multipliers. Landing gold bars in the free spins round will also earn you more free spins.

Bonanza is a highly volatile slot but with high risks come great rewards. The jackpot amounts to 120,000 while the maximum win is a stupendous 240,000 coins.

2. Book of Dead

The prequel to the Legacy of Dead slot, Book of Dead by Play’n GO, takes you to ancient Egypt and offers many ways to boost your chances of finding treasure. Although it’s been a few years since it has come out, this slot has stood the test of time, and with good reason. 

When the book symbol lands in a minimum of 3 places, the free games start. A symbol is selected at random and this will expand across any reel it lands on, meaning you receive a payout on any win. The symbol expansion takes place afterwards, getting you even more wins if new combinations are created.

Excitingly, Play’n GO also included a Gamble option, allowing you to double your win if you correctly guess the colour of a face-down playing card, or if you’re feeling particularly daring, to quadruple your win by picking the correct suit.

1. Starburst

No other slot but Starburst could take the much-coveted first place. It has almost been a decade since NetEnt released this classic game, yet it has consistently remained the most popular online slot.

With its simple design and rewarding payouts, it is no wonder that Starburst is such a hit with both new and experienced players. Like the gift that keeps on giving, Starburst is a low volatile slot, meaning that you get more frequent wins. Nevertheless, you can still win up to an astonishing 50,000x your bet

Just in case that wasn’t enough to cement Starburst in our #1 spot, the slot also has a Win Both Ways feature and a Starburst Wild symbol to help you grab even bigger wins.
