Thunderstruck II: no portrait, and three sets of maths
A 2010 slot with three licensed return configurations and no upright build. The load is fine at 2.1 seconds. Everything else is its age showing.
The phone check
Sideways is the only layout and the buttons are built for it. Fine in two hands, awkward hanging off a pole on the subway. The demo pulls about 9 MB before the first tap registers, which on a poor bar is where the 2.1 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 (Microgaming) licenses 3 configurations of Thunderstruck II. The spread from top to bottom is 3.70 points, which is about C$37 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 | 96.65% | 3.35% | baseline |
| Middle build | 94.35% | 5.65% | C$23 |
| Lowest build | 92.95% | 7.05% | C$37 |
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.
3.7 points between the best and the worst
96.65%, 94.35% and 92.95%. That spread costs about thirty seven dollars per thousand staked between the top and the bottom, and the Great Hall of Spins looks exactly the same in all three. The rules footer inside the game is the only place the figure appears.
Games Global licenses several of its older titles this way. Jurassic Park and Terminator 2 do the same thing.
On the handset
