Megaways Jack Slot Game Background

Iron Dog Studio is an iGaming developer that creates superior gaming experiences using the Megaways game engine as classic slot games like Dwarven Gems Megaways shows. Megaways Jack was the studio’s sophomore effort in crafting a Megaways slot after the swashbuckling slot game. Visually the slots don’t share many similarities. Look under the hood, however, and you’ll see many of the same bonus features.

Megaways Jack Game Design

Megaways Jack is a 6-reel online casino game with anywhere between 2 - 7 rows, depending on the on-screen action and the size of the symbols in view. The slot also offers the standard (for a Megaways slot) of 117,649 paylines and a potential maximum payout of 25,000x the stake. Unlike most Megaways slots, Megaways Jack doesn’t have an extra horizontal reel that sits above or below the main game grid.

The slot takes place in a fantastical land. The left side of the screen is taken up by a bright and cheery village house complete with a red tiled roof. Behind this rises a tall, grey mountain. The right side of the screen shows the beanstalk itself, rising high above the clouds. Between them flows a gentle deep blue river. The backdrop in this is almost as vibrant as the popular Irish themed Rainbow Riches Megaways slot. The game grid is set in an ornate golden frame, with a large harp that hangs off the left-hand side and can award random prizes in the base game. The reels contain symbols that lean on the storybook alongside vine-entangled royal playing cards. The game logo sits squarely on the top left of the screen. The Megaways counter is positioned directly below this.

The music in this Megaways Jack slot also heavily leans into the storybook trope by having a lilting, whimsical soundtrack dominated by flutes and punctuated by someone plucking at a harp. The music becomes more uptempo when spinning the reels, with drum beats coming to the fore alongside other musical instruments.

Megaways Jack Mobile

Megaways Jack is available on desktops, tablets, and mobile platforms like Android and Apple. All you need is a stable internet connection or mobile data. Players can also download the Lottomart Games app for the best experience possible.

Megaways Jack Slot Symbols

The lowest-value symbols in this Megaways Jack slot are inevitably the royal playing cards, which are utilised heavily in UK casino games nowadays. Each number/letter has a distinct value for 6-of-a-kind on the reels. The 10 and J cards have a payout of 2x the stake, while the Q, K, and A symbols have a higher value of 4x the stake.

The cow and goose symbols have a payout of 6x the stake for 6-of-a-kind. Meanwhile, the old lady symbol has a higher payout of 10x the stake for 6-of-a-kind. The highest-paying symbols are Jack and the giant, with a payout of 20x the stake for 6-of-a-kind.

No self-respecting slot would be without its bonus symbols, and the Megaways Jack slot game is no exception. The Wild symbol, represented by a golden egg, appears only in reels 2, 3, 4, 5 and 6. It substitutes for all other symbols apart from the beans. The bean symbols appear during tumbles in the base game. Each symbol adds 1 - 3 positions on your way to Free Spins.

Megaways Jack Bonus Features

Iron Dog Studio has packed a slew of exciting bonuses and features into this Megaways Jack slot release!


After a winning combination gets paid out, all symbols that participated in the said win are destroyed while the remaining ones tumble down. All destroyed symbols get replaced with symbols from higher up on the reels. There’s a higher chance of landing Wild and bean symbols during a tumble. Should the new symbols form winning combinations, these also get paid out. Tumbling stops when no more winning combinations get formed.

Golden Harp

The golden harp hangs off the left side of the game grid and awards the following prizes.

Base Game
  • Up to 4 additional Wilds from a tumble.
  • Up to 5x multipliers on winnings.
  • Up to 3 positions on the beanstalk.
  • A respin without losing your position on the beanstalk.
Free Spins
  • Up to 4 additional Wilds from a tumble.
  • Up to 3x on the global Free Spins multiplier.
  • Up to 4 additional free spins.

Free Spins Feature

Triggering the Free Spins feature in this Megaways Jack slot requires lighting the first 8 leaves of the beanstalk. This awards 8 free spins and causes the scenery to change. The setting is now among the clouds. The left side of the screen now shows a castle, while the right side shows the beanstalk at its zenith. Each successive win lights one beanstalk leaf, which then awards extra spins and multipliers. The harp and bean symbols can also help to light beanstalk leaves.

  • 9 leaves = 9 free spins.
  • 10 leaves = 10 free spins + 2x multiplier.
  • 11 leaves = 11 free spins + 2x multiplier.
  • 12 leaves = 12 free spins + 3x multiplier.
  • 13 leaves = 12 free spins + 3x multiplier + extra chances of triggering harp modifiers.

Any reel containing 7 symbols during the Free Spins round gets locked at that number of symbols for the duration of the feature. An additional multiplier then gets added. On the last free spin as well, the locked reel awards 1 extra free spin that can also re-trigger.

Additional free spins can also be awarded via successive tumbles. A minimum of 4 is required to trigger an extra 2 spins. Additional tumbles over the required 4 award an extra spin up to a total of 4.

Megaways Feature

The incorporation of the Megaways engine means that each reel can reveal a certain number of symbols in view. Landing consecutive symbols on all reels after a spin could lead to a maximum of 117,649 ways to win.
