As we head into the Summer months, you can expect to see a number of fantastic new slot games to play. Warmer months usually witness a drop off in the number of gamblers playing at online casino sites which is why developers usually save many of their best slots for the summer months, so that they can attract more gamblers to play online.

June 2021 has arrived and you will be able to try your luck on hundreds of new online slot games which will be released this month. Although there are far too many to list here, the team here at SlotsHawk.com are delighted to showcase to you the top 20 most anticipated slots of June 2021. We have also provided you with the slots developer and the release date.

If you cannot wait to play, you should head over to our online slots games page where you will discover some of the best video slots to play in the UK.

June 2021 will bring to us a wide variety of different slot releases. But, perhaps unsurprisingly, we will see the release of several more Megaways slot games. These slot machine types continue to generate lots of hype among UK gamblers. Invaders Megaways by WMS is the one to look out for here, we expect big things from this slot game.

Online slot players will also be treated to the Slingo Originals release of Slingone Fishin. We are extremely excited about this Slingo slot which will be available to be played at Slingo sites from June 22.

The SlotsHawk team can hardly wait for Cleopatra 2 slot from IGT. Our team are a huge fan of Cleopatra slots so we are eager to play the latest release. The maximum payout is 50,000x and you can bet a maximum of £600 per spin, so we expect huge wins from this IGT slot. The medium variance aspect means the game is well balanced too.

The latest release from master slot developers NetEnt is Codex Fortune. Set to be released at the end of June, this slot is based on the famous Florentine codex. This is set to be one of the best NetEnt releases this summer. The high variance aspect ensures plenty of excitement awaits.

If you are on the lookout for slots with high RTP levels this summer, then we recommend playing Beef Lightning which is set to be given an RTP of 96.43%. High RTP slots offer you the best value for your money.

As always, you can play all of the latest slot game releases at our pick of UK slot sites.


The mid-point of June will see the release of Cleopatra 2 which has got me extremely excited. With plenty of bonus features including free spins, two bonus features and lots of multipliers and wilds, Cleopatra 2 could become one of the best slot releases in 2021. With a maximum win of 50,000x and huge stake levels, Cleopatra 2 will become a perfect slot for high rollers as well as for players searching for slots with the best payouts. i cannot wait to get my hands on this video slot!
