Thunder Shields Slot (IsoftBet)

Thunder Shields Slot (IsoftBet)Thunder Shields follows closely in the footsteps of previous slots by IsoftBet, and especially the Hold & Win series. This mechanism relies on re-spins, and in this review, I will share my experience with Thunder Shields slot:

Game Set-Up

IsoftBet has set this slot on 5x4 reels, with up to 40 active lines.

The slot offers several features that include re-spins, multipliers and several other modifiers.

Betting and Prizes

The wagers will be between $0.40, and $40 per spin, and with the help of features like multipliers, Thunder Shields will deliver as much as 4,035x the stake per spin.

The regular symbols will deliver much lower wins of 6.25x per pay line (250x for a full screen).

Thunder Shields is a medium-high volatility slot, with an RTP of 96%.

Thunder Shields Slot Features

One of the available features is the wild that is also used as a substitute. Additionally, it’s also part of the Colossal Respins.

A Colossal Respin works by uniting the first two columns, which in return gives you a respin. On the colossal area, you will get a single giant symbol.

If an extra wild appears within the same respin, the feature will go on to add an extra reel within the giant area. The final product will be giant symbols located on a 4x4 area (on the slot’s first four reels).

Initially, the respins will get a 2x multiplier, and eventually, you move on to 3x, 4x and so on. Additional respins will come once you land new wilds.

Stacked mystery symbols are the other feature on Thunder Shields, and I had lots of fun using them.

Mystery Spins are random features that deliver mystery symbols on at least 3 reels. They will later be changed into one type of symbol.

A common trend with slots nowadays is the use of a Hold & Win bonus game. Isoftbet has considered that and it can trigger via special Cash Shield icons.

They land in scattered form delivering a prize whose value is 250x the stake. You will need at least six to trigger the feature.

Theme & Design

Thunder Shields has borrowed inspiration from Viking warriors and their ships. Actually, you will notice the design of the reels appear to be onboard the longboats, and the round wooden shields are strategically placed on the sides.

The Royals are among the available symbols: others include Viking warriors consisting of four men and a woman.

The developer has given the slot an excellent design, and the quality is the same great one that has been associated with IsoftBet.


Thunder Shields has one of the longest lists of features, and this is a good sign that there is no chance of getting bored while playing.

The potential is good, and so is the RTP and general graphics, plus the design of the slot.

Given that it’s a medium to high volatility slot, Thunder Shields is suitable for all levels of players.
