Hundreds of online slot games have already been released this year, and if one thing is clear, all the big casino software companies have been busy creating brand new slot designs. Our expert casino team has taken the time to play through the top games and handpick a selection they deem to be the best online casino slot games so far of 2021 which are available at online casinos. The likes of Microgaming, Slingshot Studios, and Play’n GO are all in the mix. The first one on our list is not something many people expected from its creator, NetEnt. The studio is behind some of the biggest ever slots. 2021 was the year it decided to re-release one of its big-hitters with some huge extras bundled in for good measure. So, first up, we have Starburst XXXtreme, the iconic slot game that now packs a bigger winning punch than ever before.
Best Casinos for Slots
1 – Starburst XXXtreme (NetEnt)
The original Starburst slot game needs little introduction as it still holds a place in many of the top casino game featured lists. The game didn’t need an update, but NetEnt’s re-release this year was certainly a welcome appearance to millions of slot gaming fans across the world. Starburst XXXtreme is bigger, better, and it holds a lot more winning potential than ever before. One major addition is that the new XXXtreme spins can be bought at any time to bring guaranteed wilds onto the reels. For anyone new to the Starburst experience, wilds equal big cash prizes. NetEnt’s decision to create an updated version of the Starburst slot has been huge news for everyone, and it’s almost certain to be one of the biggest slot releases of 2021.
2 – Immortal Romance Mega Moolah (Microgaming)
2021 is proving to be a popular year for gaming providers reinventing their most popular games. Immortal Romance is one of Microgaming’s biggest games, and this year sees it blended into the biggest ever online slot jackpot series. Mega Moolah is known for its multi-million jackpot prizes, and now Immortal Romance gets in on the progressive jackpot action as well. The vampire-themed slot game still offers the highly rewarding Chamber of Secrets and Wild Desire features. But now, the chance of winning a prize worth millions is sure to take Immortal Romance onto a higher level of popularity than ever before.
3 – Hell’s Kitchen (NetEnt)
Hell’s Kitchen by NetEnt is one of those games that took us by surprise. Gordon Ramsey and his Hell’s Kitchen series started in the UK, but it soon jumped across the water and enjoyed success in the US. Yet, the idea of the TV show turning into a slot game is still not something that comes naturally. Play a few spins, though, and you’ll soon find out why we included the game on our list. The fiery graphics and animation look wonderful on the reels, and the Team Challenge bonus game and Ramsay Wilds provide the bigger prizes in the game. Combine this with the low volatility, and you have a slot that plays into the budgets of all players. Will it have the same success at USA Online Casinos as the show did? We think so.
4 – Queen of Alexandria WowPot (Neon Studios & Microgaming)
Neon Valley is the studio behind the Queen of Alexandria WowPot slot game. This slot creation is a unique game release exclusively set aside for Microgaming. The Mini, Minor, Major, and Mega jackpots are fixed amounts, and landing the in-game diamonds on the reels will help you to trigger the all-important Bonus Wheel feature. It is here that you can find those huge cash prizes. It’s true that you can find multiple other jackpot games that have been released this year, but Queen of Alexandria has already paid out big jackpots on multiple occasions. A jackpot slot game that willingly pays out? We think that fact alone is why this title deserves its spot on our top slots of 2021.
5 – Odin: Protector of Realms (Play’n GO)
Our fifth game on the list is from Play’n GO and brings a slightly different gaming experience. The Odin: Protector of Realms slot game is played on a hexagonal grid that uses the modern cluster pays feature like the famous Aloha Cluster Pays uses. Symbols drop down into the grid, and you need to land at least five symbols in a cluster to start picking up prizes. Odin’s Ring Meter and Forge Meter are closely linked to the game, and these are powered up with every win you spin. The more wins you manage to put together, the greater the winning potential becomes. Random symbols, multiple wilds, and upgraded symbols all await as you reap Odin’s Power, Glory, and Wisdom features.
6 – Game of Thrones Power Stacks (Slingshot Studios & Microgaming)
Our sixth and final slot game is based on the biggest TV show of recent times. Much like the first game on our list, Game of Thrones also needs no introduction. Slingshot Studios is the team behind the game. For those in the know, Microgaming, Slingshot’s parent company, also stepped into the GoT slot territory in recent years. So, there is a winning formula to build off here. The game this time around is based on the Power Stacks feature and comes with all the famous character symbols and iconic backdrops. Jackpots, Link & Win, and Super Stacks all await as you fend off the White Walkers and spin your way to the iron throne. Slingshot has given you the perfect excuse to head back into the world of fire and ice!
