About Thunder Screech

Thunder Screech from Play n Go was released in February 2021. This is a game studio that can switch from high variance grid mayhem in titles like Reactoonz 2 to populist rock n roll games like Def Leppard at the drop of a hat. It is why they continue to be such a popular choice for slots fans. For Thunder Screech the action takes place in a prairie setting and whilst the variance has been dialled down to medium, the mix of Thunder Multiplier Wilds of up to 9x and Free Spins suggest this game can still knock out some pretty tasty win sequences.

Prairie-themed slots tend to draw on the epic settings of North America – think Wolf Howl by Just For The Win or Bronco Spirit by Pragmatic Play – but for Thunder Screech Play n Go have taken a more budget approach with a cartoon style more reminiscent of Disney. Illustrated mountains and forests form the backdrop whilst the reels are a mix of native Indian styles and almost photographic-level animal symbols. The soundtrack mixes drumbeats, woodwinds and chanting.

Here is how the game looks loaded up to play for real at Casumo.

RTP and Variance 8/10

What is RTP?

RTP (Return to Player) refers to the amount a game will pay out in cash prizes expressed as a percentage of all the money wagered on that game. For example, a 96% RTP means a game will pay out £96 for every £100 wagered. This is an average number and will vary from one session to the next.  Read more here.

What is Variance?

Variance refers to how far a game will deviate from its RTP over time. High variance games deviate a lot and produce uneven win distributions and unexpected windfalls. Low variance games provide a more stable and even distribution of wins. Read more here.

Thunder Screech has an RTP of 96.2% in the UK which is about average for a Play n Go slot. For comparison others slots by this studio include Ghost of Dead (96.21% RTP), Hooligan Hustle (96.27%) and Boat Bonanza (96.25%). If you are looking for higher paying titles you could try Rags to Riches (97.12%) or Wildhound Derby (96.93%).

The variance here is medium and with a top payout of 5,000x the game has a similar balanced pay model to Blinged (also 5,000x top win) or Canine Carnage (3,000x top win). If you are looking for better potential from a Play n Go medium variance slot then you could try Count Jokular (8,350x top win) instead.

Paytable 7/10

This is a 5 reel by 4 row game where wins are scored by landing between 3 and 5 identical symbols on the reels from left to right across one of 10 active playlines on each spin.

Low payers are the cards 10 through to Ace, valued at between 0.2x for three 10s up to 3x for five Aces. Premiums are the wildlife, from beavers, otters and badgers to wolves and ravens. These are valued at 1x up to a massive 75x. There is also a Wild – a wooden bird – that subs in for all other symbols bar the scatters, and a variation called Thunder Wild which comes with a multiplier of up to 3x.

Finally, note the magical scatter that will trigger free spins when 3 or more land at once.


Gameplay & Features 7/10

So how do you score those big wins when playing Thunder Screech?

The name of the game here is Wilds … in standard format they simply sub for other symbols. They can drop at any time on a spin or through The Call feature in which between 5 and 9 are randomly added to the grid after a spin

Better still, you may encounter a Thunder Wild that looks the same but displays a multiplier of up to 3x. These always trigger re-spins in which they stick whilst their multiplier increases by 1x on each spin. These can combine with other Thunder Wilds to from win lines with multipliers of up to 9x.

Or, Thunder Wilds can also created by The Strike, a lightning bolt that hits the reels and upgrades ALL Wilds to become Thunder Wilds.

There is also a Free Spins round, triggered by landing 3 Dream Catcher Scatters anywhere on the grid. The same rules apply except players are GUARANTEED to land Thunder Wilds on every free spin. This then triggers re-spins that continue until there are no more Wilds present on the reels.


More Games Like Thunder Screech

Wolf Howl by Just For The Win – If you are enjoying spinning Thunder Screech then you might also like this North-American wildlife-themed slot by perennial Microgaming partners, Just For The Win. Wolf Howl has a higher variance so it is a riskier slot but it blows Thunder Screech out of the water for potential at 25,000x. There are plenty of Wilds and Multiplier Wilds involved to help you reach that total too.

Safari of Wealth by Play n Go – Alternatively, if you prefer Africa to North America you could try this wildlife themed game featuring majestic plains, lions and wilderbeast. It’s volatile with a 10,000x top win and offers lots of Wilds like Thunder Screech but with Expanding Reels to help boost your wins.

Our Verdict 8.5/10

Thunder Screech is not one of Play n Go’s very best online slots – it lacks the feature-packed craziness of Reactoonz 2 or House of Doom, but it is a fun play nevertheless. As prarie-themed slots go it doesn’t have the same vertiginous variance of some of Pragmatic Play’s games either, but still the combo of wilds, multipliers and sticky wilds is compelling and can bring up some decent wins in the free spins round. In short, this is simple, basic slots fun nice designs, animations and gameplay that will appeal to a broad range of players.
