New online casino games such as new UK online slots are released every week by leading software providers like NetEnt, Play'n GO, Thunderkick and more. For most, quality is more important than quantity, and that’s reflected in the best online slots found at the best UK online casinos for 2023. Here are our experts’ five best new online slot games of 2023:

Payday Pig - Booming Games

Booming Games have really stumbled onto a gem with Payday Pig. Released in June, this new slot game has proven to be hugely popular, thanks to its simple 3x3 grid and a soundtrack that feature a tune catchy enough to make playing the game worth it by itself. 

There are some nice features in this slot, including a free spins round and the Piggy Feature. No matter what your experience level with online slots is, you'll be able to get stuck right into this one and is rightly seen as one of the best new slots. 

Mochimon - Pragmatic Play

Mochimon is one of the latest online slots available at UK online casinos that tries to piggyback off the popularity of games like Candy Crush. 

The game's mechanics are quite similar to that popular mobile game. Wins are landed by matching clusters of symbols, with a maximum payout of 5,000x your stake. It's a game that's colourful, looks great and is easy to pick up and play. Since its release in February, it has become a go-to for players looking for some light casino entertainment. 

Let It Burn – NetEnt

Most new online slots come with exciting features and free spins, but are a long way removed from retro slots a lot of players will be used to. Step up, Let It Burn! NetEnt's classic-feeling slot is full of traditional slot symbols, like 7's, bells and fruits. It's a modern twist on a retro slot though, meaning there are some great bonus features. 

With 1.024 paylines, this might look like a classic slot, but it's very modern. Special Wilds and a free spins round can lead to some big payouts - the biggest possible being 2,700x your stake. Let It Burn has made a name for itself very quickly, and could, in time, go down as a modern classic slot. 

4 Masks of Inca - Foxium

Not to be confused with 9 Masks of Fire, this new slot from Foxium is an Inca-themed online slot with a whopping 20,000x maximum payout. On top of that, there are a whole host of bonus features to help land a big win.

Wilds with multipliers, an Inca Battle feature and Inca mask symbols can all result in decent payout. The biggest wins come in the free spins round, which is triggered by landing three scatters. There's a lot going on in this slot game, and it's become an instant hit. 

10 Swords - Push Gaming

Online slots with a Roman theme have been very popular over the years, and Push Gaming will be hoping the same is true of their new release, 10 Swords. The game is on a fairly basic 5x3 grid with 20 paylines, meaning it should be pretty easy to dive into for anyone who has played at a UK online casino before. 

Free spins can be won by landing three scatters. The other main feature of the game is collecting swords. If you land, you guessed it, 10 swords, on a single spin, you will win the biggest possible payout, which is 5,000x your stake. Wins start with four swords, which will double your stake. There's a lot to like about this slot, and come the end of the year, it will surely be high up on the list of the best online slots of 2023.
