This slot takes us back to the Viking years, which is a popular theme choice within the casino industry. The slot background is set on a pirate ship, sailing in the sunset. There are noticeable animations to catch your eye such as birds flying, sails moving in the wins, and the sine of the shields. The real colour can be seen within the pirate character premium symbols.

Slot Features

Thunder Shields has 40 paylines, which are divided over five reels with four rows of symbols.

You can place bets from 0.40 per spin and that goes up to 40 per spin.

It is a medium-high variance slot. You can win a maximum of 4,035 x the total bet. That is quite substantial, but not as high as real high variance slots.

The theoretical payout percentage is 96%.

The base game of Thunder Shields is actually not that much. The four Vikings are the premium symbols and they are the only symbols that can win you a significant prize. They pay out a maximum of 6.25 x the bet for five of a kind on an active payline.

There are 12 symbols in total, this includes 5 low paying symbols. These are represented by 10, J, Q, K, and A. There are also 4 premium symbols, these are represented by grey-haired pirates, blonde-haired pirates, a female redhead pirate, and a red-haired pirate wearing a horned helmet. In addition to these regular symbols is a mystery symbol, wild, and cash shield symbol. The highest paying symbol is the pirate wearing a helmet, which pays 2.5x for 5 across a pay line. Mystery symbols land as full or partial stacks and all reveal a random regular symbol, the same symbol during the same spin. Wilds substitute all regular symbols and trigger a colossal respin.

Colossal Respins are triggered when any WILD appears on screen. The first and second reel will hold giant symbols. Landing another wild during the respin will trigger an extra respin with the giant symbol growing to cover an extra reel. Reaching a fourth respin will award an x2 multiplier which increases with +1 for each additional respin triggered by a wild.
