Eureka Reel Blast SuperLock Jackpot by SHFL Entertainment

Let’s start our best new online slots of the week by going prospectin’ with SHFL Entertainment.

Eureka Reel Blast SuperLock Jackpot is a new progressive slot from the US gambling giants that features the unique Lock It Link bonus. It started out as a popular Shuffle Master land-based slot machine but has now made the migration to online casinos.

You can also trigger wild symbols and free spins in this all-action game played deep underground (or on your laptop, whichever is nearer the surface).  

The big highlight of Eureka Reel Blast SuperLock Jackpot is the dynamite scatter. 6 or more of those anywhere will trigger the Lock It Link feature. You win 5 Lock It Link free spins, and all scatters that appear will be held in place for the duration of the feature.

You can also earn a spin of the SuperLock Wheel if you land the watermarked symbols over a scatter. Each spin of the wheel can trigger either 12 free spins, a cash prize, the Lock It Link bonus, or one of five progressive jackpots. Activate the Mini, Minor, Major, Grand, or SuperLock Jackpot.

Eureka Reel Blast SuperLock Jackpot is the perfect game to kick off these best new online slots of the week. It features 50 paylines, a tonne of features, and some eye-watering progressives. Have a blast and play it for free today.

The Green Machine Deluxe Power Bet by High 5 Games

If you’re into big bets, you’ll love our next entry in the best new online slots of the week.

The Green Machine Deluxe Power Bet features 3 rows, 5 reels, and some truly enormous special bets. Instead of matching symbols on paylines, you win money by simply adding up the cash totals displayed on the reels.  

But this is no ordinary online slot. By choosing the Power Bet, you can increase the number of rows to give you a better chance of a payout.

The Power Bet function has always proved popular with H5G slot fans. At any time during the base game, you can make an additional Power Bet worth 10-40x your stake. You will receive 15-25 special Power Bets to use on the game.

At the start of a Power Bet spin, one extra row is added to the game screen. After 5 Power Bets, the reels expand by one more row again. This keeps happening for the duration of the feature.

So, if you select 15 Power Bets, the reels will increase to 6 rows by the end of the feature. They increase by 7 rows if you select 20 Power Bets, and by 8 rows for 25 Power Bets. While the outlay is huge when making Power Bets (up to 65x your original stake), it can increase the RTP by 95% to 96.5%.

So, are you ready to give this deluxe slot machine a powerful spin for free at VegasSlotsOnline?

Age of the Gods Norse: Ways of Thunder by Playtech

It’s time to rejoin Thor as we take another visit to Asgard with Age of the Gods Norse: Ways of Thunder.

In this new Playtech game, you get to play the All Ways system with up to 3,125 ways to win. Unlock bonus symbols and win Thor’s free games as our hero wields his mighty hammer to defeat the monsters.  

You may remember we reviewed Age of the Gods Norse: King of Asgard recently at VegasSlotsOnline. It was the first in Playtech’s new range of Norse-themed slots aimed at giving fans of the original Age of the Gods games something new to play.

Playtech have wasted no time in bringing out another game in the series. Age of the Gods Norse: Ways of Thunder sees us joining Thor, the mighty God of Thunder, as he heads off on his adventures.

The 5-reel game starts off with a handful of win lines. But most reel positions are frozen in ice, and frozen out of the game. You can unlock more ways to win on every consecutive winning spin. Bonus symbols will also help to unlock win ways.

3+ bonus symbols trigger a free games round. You can win 8-50 free spins, and the reels will even expand. Best of all, expanded reels will carry over into the base game.

We are big fans of Playtech’s Age of the Gods slots, and this Norse-themed addition might be one of the best yet. Try it for free at VegasSlotsOnline.

20,000 Leagues Under the Sea by Probability Jones

To finish our best new online slots of the week roundup, we’re going on an adventure of a different kind. Probability Jones are taking us deep under the water in 20,000 Leagues Under the Sea.

This online slot is based on the classic Jules Verne novel about Captain Nemo’s secret adventures aboard the submarine, Nautilus. The game has 1,024 ways to win and a superb visual style with some excellent graphics. But then, we’ve come to expect that from Probability Jones, the makers of Bird Jewelled and Red Hot Win Spin.

20,000 Leagues Under the Sea uses the cascading reels system. After every winning spin, symbols will disappear, triggering a cascade of other symbols. The dive meter will increase by one and you move on to the next level. With every dive of the submarine, the lowest-paying symbols are removed from the reels in yet another cascade.

You can trigger free spins with 3+ bonus octopus scatters. You will also earn Nerve Points which can trigger more spins. If you survive a ‘dive cycle’ of 5 winning spins, your win multiplier will increase by 1x. And if you descend 20,000 leagues, you get to take on the giant squid. Earn stacked wilds and multipliers to bag big wins.

20,000 Leagues Under the Sea is as volatile and action-packed as Jules Verne’s story. Play it for free today.
