Thunderstruck II Video Bingo free play is a mixed concept, blending fantastic ideas from slot machines and the bingo game, highlighting the natural connection between these two beautiful games. Thunderstruck II Video Bingo uses 4 distinct 5x3 grids, with a series of numbers ready to match their respective place, offering stunning results. The format is relatively simple, and the game rules are more accessible than expected, so we recommend inspecting our review of this NekoGames creation.
Theme and Design
This slot machine features a simple interface highlighting the importance of a comprehensive yet straightforward view, facilitating a direct gaming experience. The background is simplistic: a shining-grey wall showcasing a blueish tint, forming a soothing setting.
In terms of coloring, the principal shades are pretty nuances of blue and silver, present in most game buttons and other design elements, such as the cases depicting matched bingo numbers; other nuances include green, red and golden.

Most game elements revolve around the spectacular Norse mythology, with some overt references featuring next to some inspired different design cues. The clear inspiration illustrates components such as Thor himself, standing on the screen’s left side, and other deities of the same pantheon serving as titles for the winnable jackpots: Odin, Loki, Thor again, and the Valkyrie.
The animations have a pretty modest repertoire, with some thunder-related content directly tied to the bonus features; although not many, these animations have decent quality, complementing the slot.
The soundtrack has an immersive background tune, mostly using drums as the main instrument, but also features sound effects, including heartbeats and thunder.

Wager limits
At first glance, the betting options don’t necessarily look impressive but offer a decent waging range, especially considering the customizability. Although you can’t change the paylines per se, you can turn on or off 3 of the 4 grids; considering your bet is coin per grid, playing on a single field will cost 0.01 credits, whereas the maximum bet on 4 grids is 40 credits.
Bonus Features
- Asgard Chambers: when completing a certain payline, you will activate this fantastic bonus round involving a mini-game with 5 levels. Each level consists of a choice between various objects, one featuring the ‘Collect’ message, the others offering prizes. Each time you select a prize, you move on to the next round, while the collect function automatically returns you to the base game. Ultimately, you will receive the total prize value when completing the round or collecting. Quite notably, the Bingo prize overrides the triggering of this situation.
- Hall of Picks: triggers under the same conditions as the previous characteristic, only starting thanks to a different line; the playing format also works on the same principle as the one mentioned above, but with increased difficulty, considering you must pick from more items.
- The Great Hall of Jackpots: is the Valhalla of bonus features, serving as the jackpot mechanic. Thor’s hammer sits between the grids, collecting coins dropped after electing to purchase extra balls; when the hammer fills, the Thunder God will land on your screen and then rise again, activating the characteristic. You need to choose from a coin collection while picking 3 identical coins means their respective jackpot. Their values work on a multiplier based on the coin value and are the following: Valkyrie (x50), Loki (x250), Odin (x2.500), and Thor (x10.000).
RTP & Volatility
Thunderstruck II Video Bingo RTP reaches 95.13%, working considerably below the industry average of 96%. The game volatility is high, prioritising fantastic winnings rather than consistent rewards.
Symbols
The symbol collection has different elements than regular slot machines, considering it employs a different system having its base in different slotting.
All relevant symbols are essentially numbers: they can either appear on the 4 bingo grids or in the collection of extracted digits. When matching numbers from these two categories, they will turn blue. Another element involves the extra balls you can purchase after various spins.
Other examples of game elements that serve as symbols relate to the bonus rounds, including the artefacts mentioned in the Bonus Features section of this Thunderstruck II Video Bingo slot review.
The only traditional special symbol we can mention is the Wild ball, which substitutes a number and aids in the quicker formation of paylines.
How to play Thunderstruck II Video Bingo
Thunderstruck II Video Bingo free play uses a comprehensive interface and spreads its button in an admirably organised manner. Before going into detail about them, we must mention that you will find all the paylines displayed above the grid. Below the lines are the current jackpot values, calculated according to YOUR selected coin value.
Topmost are two general functions, the game history standing in the left corner, whereas the help option, offering general information, stands on the right.
The bottom left corner features the menu containing your betting history, sound settings, the paytable featuring amazing payouts, and the betting modifier.
The bottom right corner has the ‘play’ button, which you must press to start your experience. The auto spin feature sits below it, followed by the game speed option, allowing you to choose the slot machine’s tempo.
After spinning, you will receive the ball collection and, when relevant, extra balls. To use these additional balls, you can either press the play button or click them individually. If you want to move to another opportunity for amazing rewards, the autoplay feature turns into another button, continuing to the following round. Another notable detail involves the grids, all featuring an ‘x’ option in their top-right corner, instantly deactivating them.
SlotsCalendar tips: the autoplay feature is highly customisable, including the number of spins and limiters involving loss and win thresholds; to ensure responsible gaming, we recommend using them.
