Introduction
Dive deep and see if you can battle the sharks to make a splash in this Play ‘n Go slot with a deep sea theme. Discover the bite of this slot machine as you enter the deep in the hopes of uncovering scatters, respins, retriggers, and symbol transformations. Can you net the Mega Don, or will you become prey alongside the shrimp and minnow in this 5-reel, 4-row game?
Theme, Graphics & Soundtrack
This is an ocean-themed slot, and the symbols are split into predators and prey. Keep an eye out for sharks such as hammerheads and great whites, along with barracuda and marlin. The smaller fish in the pond include shrimp, minnows, puffer fish, and box fish.
The game starts with a Jaws-like snapping shark leaping out at the screen with you and continues in a similarly menacing vein. The grid is slightly non-descript, but the circling, shadowy sharks beneath certainly remind you of where this game is supposed to be set - and who’s likely to be in charge of the action.
Bubbling water sounds and a fairly energetic soundtrack accompany the action and add to the atmosphere of the game. If you don’t like this, however, simply hit the 3-bar button and then the Settings choice. This is where you will find the sound controls.
If the theme of this slot machine is not for you, don’t worry; there are plenty more choices out there. We have literally hundreds of free play online slots, including the Double Bubble slot.

Mega Don RTP and Variance

How to Play the Mega Don slot
Jump in and start swimming and spinning straight away with the help of the following tips for playing the Mega Don slot machine.

- As mentioned previously in this Mega Don slot review, the settings menu is where you will find the sound controls. This is also the place to look for fast play settings, the chance to set the machine to auto adjust your bet according to how much you have in your credit pot, and the option to play in left-handed mode.
- The bet settings allow you to use a sliding scale to choose your stake. Choices range from 0.10 to 100.00 per spin.

Mega Don Bonus Features
Mega Don has a range of bonus features. Let’s take a look at the specifics of what this choice of free slot games can offer you if you decide to give it a spin:
Upgrading Symbols
As many as 3 of the small fish, lower-value icons can be chosen to be upgraded into one of the bigger fish options.
Shark Feast
Land at least 3 of the scatters to launch the Shark Feast bonus. The more scatters you land, the more initial symbols you get and the more upgrading symbols you can enjoy.
The Shark Feast options are:
3 scatters for 6 free spins and 1 upgrading symbol
4 scatters for 9 free spins and 2 upgrading symbols
5 scatters for 12 free spins and 3 upgrading symbols
Transforming symbols that appear on the grid will become one of the shark icons, and selected upgrading symbols stay active until the free spins bonus ends.
There is also the chance to retrigger the bonus, and what you get, once again, depends on how many scatters you land as you play. The choices are:
3 scatters for 3 extra free spins and 1 extra upgrading symbols
4 scatters for 6 free spins and 2 upgrading symbols
5 scatters for 9 free spins and 3 upgrading symbols
There is the chance to win up to 21 free spins.
Wilds
There are wild symbols in the game that can substitute for others except for the scatters to help you create winning combinations.
Mega Don Review
Overall, this is a good-looking choice of online slots. If you’re a fan of sharks or movies such as Jaws, you may like the drama that this game manages to create.
When it comes to gameplay, this choice of free slot games offers plenty of action. This particularly relates to the retriggerable free spins and the upgrading symbols, which can really make a difference to your prize pot.
The theoretical return to player is another positive feature of the slot, but the volatility may be too high for some. This game definitely won’t be for you if you like the regular, small wins associated with lower-volatility free slot games.
