Slot details & Wager limit

The playing field has 6 reels, 7 rows, and 117,649 paylines. Before starting the session, you should decide on the size of the stakes. Stakes range from €0.20 to €20 per spin.

As in the original, it's all about getting enough wins in a row to fill the counter that triggers the Bonus Round. Luckily, there are some bonuses to help you with that, namely magic beans and a golden harp. By the way, the harp can give 1 of 4 features: Wild, Golden Leaves, Freeze the stem level or increase the multiplier. The great happiness lies in having an "unlimited" progressive multiplier for the winnings that you will receive in the Bonus Round. Also here you can get a lot of pay lines and start multipliers.

Megaways Jack RTP and Volatility

6.7 

High risk comes with a 96.20% return.

Like most flashy releases on this mechanic, Megaways Jack has high volatility. This means that you can win a lot here in just 1 spin, but you should also expect a lot of dead spins between unexpected rushes of luck. RTP is 96.20%, which is higher than the market average.

Theme

7.8 

The seller offered Jack, the main character of the slot and the famous British fairy tale, to exchange a cow for magic beans, from which a stem will grow up to the sky. An angry mother threw them out the window and the next morning Jack discovers that the old man was telling the truth! To the right of the reels is a beanstalk leading to the giant's castle in the sky. Climb it, making winning combinations to get the maximum win!

The heroes of the popular fairy tale came to life on the playing field of this slot machine. Boy Jack, his mother, a giant living in the sky, Golden Goose, and the Cow play the role of premium icons. Royals Ace-10 got the smallest values.

Please note that this slot machine has a bunch of special symbols and we recommend that you familiarize yourself with their purpose before starting a session. The Golden Egg is a Wild that replaces all standard icons, magic beans only appear on tumbles during basic spins and each such symbol adds 1, 2, or 3 positions on your way to free spins. There is also a Magic Harp which gives a bunch of additional bonuses!

Bonus Rounds & Free Spins

6.8 

Free Spins

Launching the free spins feature is equal to creating a golden path to the riches of the giant in the sky. There are 8 leaves on the right side of the bean stem. Convert them all to gold using magic beans and you will get free spins!

Of course, you can turn more leaves into golden ones: 8, 9, 10, 11, 12 or 13 golden leaves will give you 8, 9, 10 (with a multiplier of 2x), 11 (with a multiplier of 2x), 12 (with a multiplier of 3x), or 13 (with 3x multiplier and increased chances of landing harp) free spins, respectively.

During the feature, an unlimited progressive win multiplier is in effect. It starts at whatever gold leaf-level you have reached (as described above) and will increase by 1 point for each win.

How to get extra free spins? Simple enough. You will receive 2 Extra Free Spins when you get 4 consecutive wins, as well as 1 Extra Free Spin if you lock the reel on the last Free Spin.

You can also use the Bonus Buy option and buy the free spins feature, perhaps even with some perks.

Max Win

7.5 

Climb the bean leaves into the sky and the giant will give you 25,000x!

The potential of this slot machine is 25,000x the stake. That's a lot if not compared to Pirate Kingdom Megaways. Most likely, you will hit the maximum win in the free spins feature with an unlimited progressive multiplier.

Overall Rating

7.2

Comparing this slot to the 1st game by Iron Dog powered by Megaways is okay as this is just their 2nd use of this engine. There are some similarities, but still, Megaways Jack has enough unique theme/features to stand on its own 2 feet. The volatility is high as in the original and the maximum win of 25,000x has dropped significantly, but it's still good.

Hits
Random golden harps in the base game (up to 4 features)
Free spins feature with an unlimited progressive multiplier
Max win of 25,000x the stake
Misses
Potential lower than Iron Dog's first Megaways game
High volatility
