Monster Blox Slot Review

Yggdrasil Gaming has always been among the most innovative developers on the market. We’re not just talking about graphics – its slots always look gorgeous. We’re also talking about gameplay features that the studio has been obsessed with. In the past few years, Yggdrasil’s best slot titles have revolved around gigantic symbols that the studio calls Blox, and that’s the premise of its release too.

Developed by Peter & Sons for Yggdrasil, the Monster Blox slot is a highly volatile title with an RTP of 96.10%. The slot has 40 paylines to win across paired with 6 reels. It’s a slot with a medieval setting and lively graphics and colors with innovative gameplay at its core.

You can play the Monster Blox online slot at most top casino online offering Yggdrasil slots. Try it for free first to learn how those massive blocks work and then you can proceed to play for cash and win rewards over 7,000x your bet.

Monster Blox Slot Paytable, Layout, and Controls

In terms of setup and layout, Monster Blox doesn’t look very out of the ordinary. It’s a 6x4 slot game with symbols of various sizes. The setting is a brick house with reels within. The slot’s rows can expand which makes the building expand appropriately. Those bloxes can land as 6x6 symbols and deliver some epic wins, even in the base game.

As expected, there are premiums and low-paying symbols on the reels. The top payouts are 10x your stake for 6 of a kind, while the low-paying card royals pay significantly less. A free spins symbol is a Scatter that gives you entry into the bonus round.

The Monster Blox slot is quite the looker as expected out of Yggdrasil’s titles. The soundtrack and audio effects are on-point too, so from an audio-visual perspective, this is a slot that’s unmistakeably made by Peter & Sons.

Monster Blox Slot Mobile Availability

The Monster Blox slot was developed on the HTML5 platform, so it’s available on a range of Android and iOS devices. No need to download slot apps to play it. Just head to your favorite casino and spin it from your browser.

How to Play the Monster Blox Slot

Set a bet between $0.20 and $100 and you can set off on this medieval adventure by clicking on the Spin button. The reels will turn with a nice animation, with symbols landing on them also being animated. Whenever there’s a chance for a Blox symbol to drop the reels will turn a bit slower until it lands.

Any winning combination will give you a respin. During it, the reels will expand to 5x6 and the paylines by 15 betways. If you win, you get another respin. This can go on infinitely, with a maximum panel size of 6x8 with 100 paylines. As expected, reaching that size certainly increases the slot’s winning potential, so expect massive wins if you manage to expand the reels by that much.

See the hunter with that magical weapon to the left? At any point in the base game, he might shoot the reels with it and transform any symbol to a Wild. This is called the Wild Bounty feature and can also turn Blox into Wilds.

This happens more frequently in the Free Spins round which also comes with a few unique features.

Monster Blox Slot Monster Free Spins

Landing 5+ Scatters in the base game gives you access to the Monster Free Spins round. The bonus round is played on a 6x8 panel with 100 paylines. The number of free spins players get is equal to the number of triggering Scatters. So, for example, if you trigger the round with 10 Scatters, you get 10 free spins.

Every Scatter that lands on the reel further adds another one to your tally. During the Free Spins Round, all Scatters are collected in a special meter. It triggers the Multiplier feature into play with the following values:

  • 0-1 Scatter – x2
  • 2-5 Scatters – x3
  • 6-14 Scatters – x5
  • 15+ Scatters – x10

Thanks to the multipliers and the fact that the layout has been maxed out, the Free Spins Bonus is Monster Blox’s highest-paying feature.

Monster Blox Slot RTP, Max Payout & Volatility
