Here are the best online slots from 2021 to play right now

Many had hopes that 2021 would be a huge improvement from the miserable year that was 2020. Whilst, 2021 was not the miracle year that people had hoped for, it was still a solid year for online slots.

In 2021, players were introduced to some of the greatest branded slots as well as sequels to fan-favourite slots. Remember 2021 for the good times and for being an epic year filled with innovative slots.

Money Cart 2

Release date:

It's safe to say that whilst the original Money Train slot was a reasonable success, it definitely didn't match up to the mega-hit that was the sequel in Money Train 2. As one of the biggest hits for Relax Gaming, the developers decided to release a bonus game version of the slot called Money Cart 2.

The beloved bonus game from the original is the entire focus in this slot - but there is an improved win potential completely reinventing the steampunk slot. Money Cart 2 features an unbelievable RTP of 98% and is a high-octane with a maximum win of 5,000x your stake. This slot is revolutionary and easily set the trend for realising bonus game slots such as Money Cart.

When people think of branded slots, they think of low RTP and tacky graphics which act as a quick cash grab for developers. This is certainly not the case with Alice Cooper and the Tome of Madness from Play'n GO as it perfectly encapsulates the wackiness of Alice Cooper.

This grid slot plays on 5-rows with 5-columns and contains high volatility gameplay. In terms of features and charm, this slot is absolutely oozing with them both. There are multiple features including Reality Effect, Hat of Madness and Mega Wilds leading Alice Cooper to walk across the screen. This slot is both dark, tasteful and completely unmissable.

Despite being founded in 2004, Lightning Box didn't really jump onto our radars until the release of Outlaw Waysfecta. This slot acts as a soft sequel to Enchanted Waysfecta with the Waysfecta mechanic but completely stood out on its own with gameplay that you'd struggle to find in any other online slot.

The developers are known for skill-based mechanics such as Skillstar, but Outlaw Waysfecta completely cranked this up with the features. Amazingly, players shoot through a mini-game to determine which bonus they receive and the slot feels like an unmissable Wild West heist. For a Wild West experience unlike any other, do not miss out on this unique slot.
