Thunder Shields symbolVikings were a name that once struck fear in the hearts of common folk. They appeared from the sea, pillaging and raiding the coasts of Europe. They were strong warriors, fearless and always eager to prove themselves. In Thunder Shields, players will have the opportunity to join a crew of these marauders in an epic adventure. Available special features include mystery spins, colossal re-spins and the Hold & Win bonus. Plenty of loot to be enjoyed; if you survive long enough to snag some!

All the action takes place aboard a Viking ship. The background image is somewhat cramped, preventing us from making out too many details. That said, we do like how the slot changes the background image during the Hold & Win special feature. All the symbols freeze in place quite literally, as ice covers both the reels and the sails! It looks gorgeous, and is enhanced even further by gorgeous animations. Put it all together, and you have a fantastic looking game. Now let’s delve deeper into this new Labslots review.

How it Works

You play this release on a five-reel board with forty fixed paylines. This means individual paylines cannot be toggled on or off to adjust the wager. Wins are awarded by finding three or more matching icons in adjacent positions, starting with the leftmost reel. All winning combinations must follow one of the active paylines, or else it will not grant a cash prize. iSoftBet decided not to make any changes to their user interface when designing Thunder Shields. On the right side of the screen, punters can spin the reels, set up Auto Play and change their bets. Meanwhile, in the bottom left corner players can toggle sound and Turbo Mode, or open the paytable. You can wager between £0.40 and £40.00  on each spin.

The online slot does not go big on symbol designs. Available icons consist of either playing card royals or members of the Viking crew on the ship. Each member looks visually distinct, and offers a different payout. Crossed axes are the mystery symbol, and the electrified golden hammer is the Wild. Meanwhile, golden circular shields are the Scatter! All three special icons play a role in activating one special feature or another. Let us take a closer look at how that works!

Thunder Shields Bonus Rounds

Mystery symbols can appear on any spin, fully or partially stacked on the reel they landed on. All mystery icons on the board will always reveal the same symbol. Another bonus that can randomly occur are Mystery Spins. They guarantee at least three reels will land completely covered in mystery icons. Because they always reveal the same symbol, they give you an increased chance of landing a winning combination.

Wilds play their traditional role, and can substitute for any other icon on the board except for Scatters and mystery symbols. However, Wilds also trigger the colossal re-spin special feature. The initial re-spin combines the first two reels into a large one, creating colossal icons in it. If another Wild lands during the re-spin, the giant symbol grows by one reel and another re-spin is added. The icon growth can happen a maximum of four times, with the fourth re-spin also granting a 2x multiplier. The multiplier can then be increased by one for each consecutive re-spin granted by landing a Wild. It is possible to unlock the Hold & Win bonus from colossal re-spins.

Get six or more golden shields to activate the Hold & Win special feature. The shields have cash prizes on them, ranging from 1x to 250x your bet. Hold & Win grants three re-spins, and every time another shield lands, the number of re-spins is reset. The bonus is played until the re-spins counter reaches zero. Alongside cash shields, special shields can appear that further enhance the bonus. These extra shields can grant the following.

  • 2x multiplier, which doubles cash values
  • Collector, which grabs all cash values to make room for more shields
  • Reel Boost adds up to two reels to the grid
  • Cash Boost increases the cash value of all shields
  • Re-spin Boost permanently increases the number of re-spins in the counter by one
