Type of play
- “Must-play” state-based play: only play when the machine is already in Storm Mode.
How the advantage works (quick)
- If Thor lands in the center reel position, it awards whatever credit prizes/jackpots/free games symbols are showing in the other reel positions.
- Storm Mode is a paid-spin feature where:
- Hyper Spin (hammer smash that dumps lots of credit prizes on the reels) happens more often.
- Thor is ~70% more likely to land each spin.
- Net effect: during Storm Mode, the paid spins are much more likely to convert the visible prizes into awards, and plays are often strongly +EV.
