Jack and the Giants by Rival Gaming

It’s fairytale season with Jack and the Giants from Rival Gaming. Win one of two free spins bonuses, with multiway action and wild multipliers galore. Fe-Fi-Fo-Fum!

Following the success of games like 2022’s Fairytale Fortunes: Queen of Hearts, Rival Gaming returns with a brand-new adventure. Join Jack as he climbs the beanstalk to find golden-egg-laying hens and very irate giants.

You play 243 ways to win on five speedy reels in this slot. The game plays with cascading reels too: every time you land a winner, the symbols disappear, only to be replaced by the ones appearing above on the reels. Jack also appears as a wild and replaces all regular symbols to help complete winning lines.

There are two free spins bonuses in Jack and the Giants. You trigger regular free spins by landing three or more gold coin scatters in any position. You win 5–15 free spins, depending on how many scatters you land. In addition, you play on a second screen that has 1,024 ways to win, and the wild symbols gain a 2x multiplier every time they come into play.

Alternatively, you can activate the Land of the Giants free spins bonus. Wilds come with a 5x multiplier attached. Plus, you play with 3,125 ways to win, instead of the usual 243.

The two free spins bonuses are certainly the main reason to play Jack and the Giants. But we also love the whole atmosphere of the game. The light music, cute animations, and quick gameplay make Jack and the Giants one of the best new online slots of the week. Give it a play for free today.

3 Lucky Witches by 4ThePlayer

Hubble, bubble, toil, and treasure! 4ThePlayer returns with another spooky slot with a ton of great bonus thrills: 3 Lucky Witches. Trigger the Witches’ Wheel and win up to 5000x!

4ThePlayer’s collaboration with Yggdrasil continues to deliver the goods, with their latest great slot hitting casinos this month. 3 Lucky Witches follows similar slots like 3 Lucky Leprechauns and 4 Fantastic Fish with its abundance of beautiful bonus games.

The main draw in 3 Lucky Leprechauns was the trail bonus: in 3 Lucky Witches, you get to spin the Witches’ Wheel to win a range of different prizes. Not only that, but the hit rate for the bonus wheel is fairly high.

You begin by choosing your lucky witch (Ivy, Scarlet, or Celeste) who acts as a wild symbol during the game. The witch is supported on the reels with her menagerie of familiars, including a black cat and a crow.

You trigger the Witches’ Wheel by hitting three or more pumpkin scatters in any position. Spin the wheel to hit free spins or cash wins, or activate the pick-a-win feature. Best of all, the hit rate is good (once every 75 spins, on average), so it’s worth persevering with.

The pick-a-win bonus gives you a chance to choose items on the screen. These reveal cash prizes worth 20x stake to 590x.

You can also line up arrows on the bonus wheel to move up a level. Plus, you can move up levels by landing extra bonus scatters. Reach the middle of the wheel and you can win the jackpot of 5000x.

Hell Chef by Kalamba Games

We’re serving up some devilish treats next with Kalamba Games’ Hell Chef. Play up to 15,625 ways to win and unlock reels with the K-CASH bonus.

Hell Chef features a celebrity cook beaming his cookery show directly from the underworld. The unlucky recipients of the demon’s blowtorch are the K-CASH critters, who fly onto the reels to award prizes.

You only win money by lining up three or more K-CASH symbols running left to right. You can also earn special payouts during the free spins bonus on K-CASH symbols that fall within the fire area.

Plus, you expand the fire area by 1 reel if you manage to land a K-CASH symbol in each column. Any K-CASH symbols appearing outside the fire area are added to a Collect Meter at the top of the screen.

You only win five free spins to start with. However, you can earn extra free spins by filling the collection meter and frying those critters to perfection. Extra blowtorch symbols also add one or more spins to your total.

There’s certainly some hot variance in the Hell Chef game. It can be agonizing to land two K-CASH symbols on a spin and fall just short of opening another column.

However, it’s the free spins bonus that gets the temperature soaring in Hell Chef. Why not give the game a spin for free now and see what you think?

Benny the Beer by Hacksaw Gaming

Something big is being cooked up in the Hacksaw Gaming brewery. Benny the Beer is the new five-reel slot that features the Stackways mechanic which can open up the game and lead to big wins.

Hacksaw Gaming has been pushing its new Stackways mechanic hard during 2023. These five-reel slots pack a punch with medium-to-high variance and some big prize jackpots.

In Benny the Beer, you begin the play on a 5×5 game area. You win payouts in the usual way, but Stackways icons will activate a stack of paying symbols on that reel. Stackways symbols range from 2 to 4.

How does the game decide what stacked symbol should appear? Simply, it decides what symbol would help form the longest-winning combination possible among the symbols on the screen.

You win ten free spins by hitting three scatters in any position. In addition, two symbols are randomly chosen to become special symbols. Hit that symbol on three reels at once to trigger random stacks on certain reels. It’s possible to hit stacks of up to ten symbols this way.

You can also trigger the Super Book of Stackways by activating the free spins with four scatters. This time, four symbols are chosen to become special symbols, instead of just two.

The Stackways mechanic can pay dividends if you’re patient, particularly if you manage to hit two or more Stackways symbols in a single spin. The oompah jingle that plays after you win is a nice touch too. Give the game a spin for free today and see what you think.
