Jumbo Jellies Slot (Yggdrasil)

Jumbo Jellies Slot (Yggdrasil)Yggdrasil Gaming is a slot developer with a rich catalogue of games, and this year alone (2021), we have seen many new titles from them.

Before ending the year, the developer has one more title by the name Jumbo Jellies. The slot was actually designed by Bang Bang Games, for Yggdrasil, and it comes with some candy-themed graphics, which is a common idea with modern slots.

With the good prizes and many features present, I had all the reasons to try this slot for real money, and here is my unbiased review:

Game Set-Up

Jumbo Jellies uses a 6x3 reels grid, with up to 20 active lines. Several major features have been included among them respins, free spins, multipliers, and the Jumbo Row Pops.

Betting and Prizes

To place real money wagers, I had the option to pick bets of between $0.20 and $100 per spin.

I like the potential inside, and on a good day, Jumbo Jellies can pay a top jackpot of 5,432x the stake, from one spin. This is even more attractive given that the slot is medium in volatility slot.

However, the slot will disappoint you with its not so good RTP of 95.42%.

Jumbo Jellies Slot Features

The main innovation that this slot machine carries is known as Jumbo Row Pops. It is a mechanism in which the 6 reels of 3 symbols each are divided into 9 parts (2 symbols for each one). To activate the mechanic, you must create a combo in which each segment holds two different matching symbols.

This enables the row's icons to become Jumbo-sized by combining the two icons from each segment, reducing the row's symbols from six to three large ones.

When the Jumbo Row Pops mechanic is activated, more active lines are added. When only one row is active, you get 5 extra lines, when two rows are active, you get 15 extra lines, and when three rows are active, you receive 20 more lines. This method allows you to get up to 40 active lines.

You also activate the Win Streak Respins, where you begin with the initial symbols, which have been transformed into large Jumbo Wilds. To have more respins, you must keep landing new wins. When this takes place, an increasing multiplier will come in and increase it by one.

Free spins are also available on the slot, and to activate them, I needed at least scatter icons that come in the form of Chocolate Candy. Depending on the number of scatters, you can receive 6+ free spins.

A mini-game that relies on 3x3 reels is also accessible, and with it, I got extra scatters during respins. With this, up to 9 scatters can be used as a trigger, resulting in up to 18 free spins.

The use of guaranteed Win Streak Respins after any winning round is what differentiate the free spins. You also retain the formed Jumbo rows; they do not revert to their original size as is the case between paid spins.

Theme & Design

As is often the case, Jumbo Jellies carries us to a magical land teeming with candy and other sweet treats. It's bright and colourful, and it's well-designed, though I've seen better designs from this developer.

Initially, you have the four basic card suits symbols, but there are other higher-paying ones like cherries, gummy bears, soda bottles, jellies, and chocolates.


Jumbo Jellies has several advantages, especially the Jumbo Row Pops mechanism which makes this title an interesting choice. Unfortunately, Yggdrasil did not consider a high RTP, and I'm afraid that the slot will not attract many gamers as a result.
