Slot Design

Mega Monster has the standard 5×3 gameboard, with 5 reels, 3 rows and 20 fixed paylines.

The slot’s RTP is 96.00%, the volatility is set to MEDIUM and the hit rate is undisclosed.

The minimum bet per spin starts from 0.20$, while the maximum bet reaches 20.00$, a range widely used by most RTG slots.

In terms of betting menus, RTG has never had one, and they still rely on plus and minus buttons directly on the gameboard with a max bet button, quick spins button and an autoplay button.

Overall the UI is always the same for most RTG slots, with the settings menu being on the right side of the gameboard.

As usual the sounds and music are separated and can be turned off individually, and you can use the spacebar as a keybind for your spin button.

The music is decent, the symbols and animations are decent, but the theme of the slot seems out of season and we are not sure why a Halloween slot would be released at the end of March.

Slot Features

  • Wilds: The wild symbol in this slot substitutes for all symbols but scatters.

It will show up quite often during gameplay and will aid the player to complete winning combinations. During our testing, it contributed to winnings around 1x to 6x.

  • Sliding Reels Feature: This feature triggers randomly during base game and free spins. After the triggering spin all Franky symbols will turn into wilds and will award a payout. Afterwards reels 2-5 slide to the left, while reel 1 moves to reel 5 position. This feature continues until the reels have returned to their original positions.

From what we saw, triggering this feature is the rarest, but at the same time the payout is the highest as it rewarded us anywhere between 19x and 30x.

  • Wild Multiplier Feature: This feature triggers randomly during free spins and base game. All winnings will be multiplied between 2x and 5x.

This feature shows up quite often, perhaps once every thirty to fifty spins, but rarely has high returns.

  • Expanded Reels and Extra Wilds Feature: This feature can be triggered randomly during free spins and base game. The gameboard will expand to 5×4 with 40 paylines and additional wilds will show up on the gameboard.

Perhaps the least rewarding feature, as it doesn’t guarantee a win, it just doubles the paylines and that’s about it.

  • Free Spins: Landing 3 scatters during base game will award 10 free spins. Before the feature starts the player will be asked to pick a feature they would like to see more often.

Despite your choice the features will continue to work just like in base game and it’s not guaranteed that you would land it. Our overall payout on this trigger where we selected the Expanded Reels was roughly 10.2x.


Mega Monster is a Halloween themed slot, released at the end of March 2024 for unknown reasons.

The slot has decent symbols, nice animations, but the features felt lackluster.

Besides the free spins, there are 3 randomly triggered features which don’t really add much to your gameplay.

We’ve included a demo in this review for anyone to test the game, but once again RTG seem off with this one.

You can get 25 free spins on this one for the next 2 weeks however if you use Coupon code: 25MEGAFREE.

Other than that, our advise would be to not waste time on this slot and look for something more complex and rewarding.

  • Why is Mega Monster online slot rated 4 out of 10?

    We have subtracted 4 points from Mega Monster for the extremely low max win and lack of features. RTG has not released a decently complex slot with a good max win for years now. Everything we test these days appears to be simple, with almost no features. Even now, a Halloween slot released in March is mind boggling.

    Yes, Mega Monster is available on our promoted RTG casinos, which specifically are oriented towards our North American audience, hence mostly United States and Canada. They do however accept other countries which can be seen on our casino table.
