How Thunderstruck II plays
Wins pay on 243 ways, and the Wildstorm feature can randomly turn up to five reels wild. Scatters lead to the Great Hall of Spins, whose four rounds open up the more often it is triggered: Valkyrie (free spins with a fixed multiplier), Loki (Wild Magic symbol), Odin (wild ravens adding multipliers) and Thor (rolling reels with a multiplier rising to 5x).
Theme: Norse mythology. Filed under Norse and Vikings.
Features in this game
- Cascading reels: After a win, the winning symbols are removed and new ones fall into the gaps, giving another chance to win from the same stake.
- Multipliers: A value such as ×2 or ×10 applied to a win, a spin or a whole feature, multiplying the amount paid.
- Symbol upgrades: A feature that turns lower-paying symbols into higher-paying ones, or removes low symbols, for the rest of a spin or bonus.
- Free spins: A bonus round of spins played at no extra cost, usually triggered by scatter symbols and often with extra features.
What the figures mean
An RTP of 96.65% is a long-run average across millions of spins. It works out at a house edge of 3.35%, so every £100 staked costs £3.35 on average. A session of 200 spins at £1 stakes £200, and the expected cost of that session is £6.70, although the real result will usually land a long way either side. Work out your own figures.
The provider rates volatility as medium. That describes how winnings are spread: higher volatility means longer runs with little back and rarer, larger wins. It does not change the average. More on volatility, or see it in a simulation.
Published hit frequency is 32.62%, meaning roughly 33 spins in every 100 return something. Many of those returns are smaller than the stake.
