We have another tip-top best online slots of the week roundup for you. And as the summer weather heats up, so do the offerings from some of the world’s best casino developers.

First up, we have Rock the Reels Megaways from Iron Dog Studio. It’s a rocking take on the Megaways game that features a wild animal rock band thrashing its way through 200,704 ways to win.

Next, Pariplay returns with Gold’s Guardian. Brave the dragon’s den as you hit locked frames and the Super Free Spins feature.

Lightning Box Games is known for big slots innovations. And with Enchanted Waysfecta, it’s bringing its multiway innovation to an eager gambling public. Play up to 15,552 ways to win by landing the special split symbols on the middle three reels. There’s even a free spins bonus with a progressive multiplier to enjoy.

We end on something a little more old-school from Leander Games. Cash Up is a nostalgic Vegas-style slot with lots of bells, fruit, and other classic imagery. But it’s the Cash Blox bonus with multipliers that lifts the game from the humdrum. Give it a play, along with all our best new online slots of the week.

Rock the Reels Megaways by Iron Dog Studio

It’s time to get your rocks off with Iron Dog Studio and the Rock the Reels Megaways slot. Play up to 200,704 win ways in a single spin and trigger multiple modifiers including transforming wilds.

We’ve had plenty of Megaways slots in 2021 already. But we think we’ve yet to see one featuring a heavy metal theme and some kick-ass wild animals taking to the stage.

But then, Rock the Reels Megaways is the type of game we’ve come to expect from Iron Dog Studio. These are, after all, the guys who came up with Astro Newts Megaways and Megaways Jack in recent months.

If BTG needs a safe pair of hands for its Megaways mechanic, the award-winning Iron Dog Studio definitely offers them.

Rock the Reels Megaways is a six-reel slot where each reel contains two to seven symbols. There’s also a horizontal reel above the main set that can help to increase the number of win lines.

Potentially, you can hit up to 200,704 ways to win on every spin. After each successful ‘tumble’, the symbols disappear and are replaced by the ones sitting above on the reels.  

Look out, too, for the members of this wild band, including a warthog, octopus, and flamingo, which can all trigger modifiers. These include transforming wilds, additional high-paying symbols, and multiplier wilds.

This wouldn’t be a Megaways slot without a great free spins feature. You can trigger between eight and 20 free spins by landing three to six scatters in any position. You can also retrigger additional free games by landing more scatters.

There have been plenty of Megaways slots to enjoy this year. Rock the Reels Megaways is definitely one of 2021’s bolder gambling games, so get ready to spin it into action for free today.

Gold’s Guardian by Pariplay

Dare you enter the dragon’s realm and steal the gold? Gold’s Guardian is the latest fantasy-themed slot from Pariplay that features locked frames, lots of wilds, and a very special free spins bonus.  

If you’re a fan of Norse-themed slots, you might still be playing Pariplay’s Aesir Treasures with its Thunder Spin feature and four unlockable free spins modes. Well, PariPlay has upped the ante this month with Gold’s Guardian, a fantasy-themed slot with even more bonus thrills.

It’s a 50-payline slot played across five reels in a 4-5-4-5-4 arrangement. Dragons take center stage here and can add locked frames to the reels when they appear.

The dragon may also transform into a wild symbol if it lands within one of the locked frames. When it does, all adjacent locked frames will also transform into wilds.  

The dragon eggs act like scatters and trigger the free spins round when you land between three and five in any position. You’ll win from eight to 20 free games depending on the number of triggering scatters.

Plus, one to five locked frames may appear at random during the bonus round. These will remain in position until they transform into wild symbols.

While free spins can’t be retriggered, you can activate a Super Free Spins round. This happens every sixth time you trigger the regular free spins round.

You win 12, 15, or 25 Super Free Spins; but first, a wheel will spin to determine the number of locked frames to add to the reels. You can also boost your winnings with between four and 10 additional special locked frames.

On the face of it, Gold’s Guardian is another loud and colorful fantasy-themed slot. But it’s the locked frames that add excitement to the gameplay. Try it for free and see if you can unlock this golden treat.  

Enchanted Waysfecta by Lightning Box Games

We depart the dragon’s realm to reach the land of the fairies in Enchanted Waysfecta from Lightning Box Games. Play up to 15,552 ways to win with the unique Waysfecta mechanic, and trigger free spins with an unlimited win multiplier.

We’ve been big fans of Lightning Box Games for a while here at VegasSlotsOnline. Recent Asian-inspired games such as Lightning Shenlong boast great features like the Lightning Respin, where you can unlock colossal jackpots.

Lightning Box has outdone itself yet again with the introduction of a brand-new mechanic: Waysfecta. In Enchanted Waysfecta, the game starts with five reels, 15 reel frames, and 243 ways to win. However, reels two, three, and four are ‘waysfecta reels’ and can comprise split symbols or regular symbols.

The more split symbols that appear, the more ways to win there are. It’s therefore possible to play across a maximum of 15,552 ways on a single spin.

While you’re busy playing and enjoying Tchaikovsky’s ‘Nutcracker’ in the background, it’s possible to trigger free spins. You’ll also win up to 5,000x if you trigger the feature with five-of-a-kind.

You win eight free spins to begin with, plus an unlimited win multiplier that begins at 1x. The multiplier increases by 1x for every successive winning spin you land, and you’ll also win an extra free spin.

Fantasy-themed slots seem to appear every month or so. And without Lightning Box’s new mechanic, Enchanted Waysfecta might have fallen by the wayside. Luckily, this fresh take on the split symbol feature suggests that Lightning Box could be onto a winning thing.

See what you think by playing Enchanted Waysfecta for free at VegasSlotsOnline.

Cash Up by Leander Games

Let’s conclude our look at the best new online slots of the week with an old-school classic. Cash Up is Leander Games’ addition to a bunch of nostalgic slots releases for 2021. It features some great graphics and enough bonus action to please the weariest slots fan.

Cash Up is played on a set of five reels where you can win payouts by lining up the various gold bells, cherries, and melons. Above each reel is a multiplier value that changes on each spin.

When a bonus symbol lands on that reel, it will activate the multiplier above it. Multipliers range from 1x to 100x.

Look out for the bonus symbols. You will trigger the Cash Blox feature by landing three or more bonus symbols from left to right. All active multipliers on those reels are added together and applied to your bet. 

In addition, you can randomly trigger extra bonus symbols on the reels. These will lock in place before the reels stop spinning, giving you even more chances to trigger the bonus.

And if that’s not enough action, Cash Up also features a free spins bonus. Win 12 to 30 free games and aim for the special prize multiplier worth 1,000x.

Cash Up won’t blow the world away with immersive bonus features. But if you’re a fan of slick classic slots with some truly attractive jackpots, Cash Up might be for you. Give it a spin for free right here at VegasSlotsOnline.
