Thunderstruck on a phone
No upright build at all. Turn the phone or you get a rotate prompt, and it wants 1.6 s before the first tap registers.
The phone check
Sideways only, and even then the controls sit close together. The stepper is a millimetre from the button that spends money. The demo pulls about 7 MB before the first tap registers, which on a poor bar is where the 1.6 s goes. Getting money back out is a separate count and we keep it at cashout.
This title ships in more than one return build
Games Global licenses 2 configurations of Thunderstruck. The spread from top to bottom is 3.01 points, which is about C$30 in expected cost per C$1,000 staked. Same reels, same features, different maths.
| Configuration | Return | House edge | Cost per C$1,000 vs the top build |
|---|---|---|---|
| Highest build the studio licenses | 96.1% | 3.9% | baseline |
| Lowest build | 93.09% | 6.91% | C$30 |
How to see which one you are on, in three taps
- Open the demo and tap the burger or the ⓘ in the game's own toolbar, not the casino's.
- Scroll the info panel to the bottom. The return figure is printed in the rules footer.
- Compare it to the table above. If it is not the top row, that is the build you are being served.
123 of the 306 titles on this board carry more than one build, so this is worth doing once per game rather than once ever.
Where it sits on the board
Ranked 203 of 306 here, and none of that ranking is about the game. It is about the handset. Against a board median of 2.1 s that is 0.5 s of your life back per session.
Games Global has 13 titles on this board, 10 of them upright, with a median load of 1.6 s.
What the game is
A 2004 release from Games Global. Board is 5x3, 9 lines, the mechanic is free spins / multiplier. The Thor-themed Microgaming original whose tripled-win free spins made it one of the most-played slots of the 2000s.
Swing is medium. Plan the demo around that and not around whatever the first ten spins do. C$0.15 a spin, so twenty dollars runs to roughly 133 of them. Ceiling is 10,000x and it is not going to happen to you.
