Frequently asked questions
How do I get my files after purchase?
Instantly and automatically. Immediately after purchase, all files will be available for download under "Purchases and Reviews" in your Etsy account – no waiting required. Included are the eBook with data package (PDF), the calculator file, and a short welcome guide. The guide also contains your personal access details for the online calculator.
What exactly is included in the package?
You'll receive a complete set: the eBook "37 Subsystems with Guaranteed 12 Matches" (PDF, 103 pages) with a clear explanation of each system, the data package with all the completed lines, access to the interactive online calculator, and bonus systems for lottery syndicates. The calculator includes the 34 printable systems; the 3 top-tier systems are described in the eBook and are played digitally via the LOTTO app.
How does a subsystem work – and what does the “12-year guarantee” mean?
With a full system, you play all possible combinations – which quickly becomes expensive. A partial system, on the other hand, cleverly selects only a few lines and thus mathematically guarantees at least 12 correct predictions, provided your predictions accurately reflect the true outcome. The "guarantee" therefore refers exclusively to the minimum number of correct predictions with accurate predictions – not to a cash prize. Each of the 37 systems was individually recalculated for this purpose.
Do I need special software or math skills?
No, neither. The eBook is a standard PDF and runs on any device; the calculator opens directly in your browser – no installation, no account, no subscription required. You don't have to do any calculations yourself: you choose a system, enter your 13 predictions, and the calculator generates ready-made betting slips for you to copy.
How do the 37 systems differ – which one should I choose?
The systems range from inexpensive mini-systems (a few euros stake) to large systems for betting pools. The difference lies in the number of uncertain games you're keeping open and your budget: the more games you keep open, the more lines you have and the higher the stake. The eBook lists each system with the number of lines, stake, and coverage, and the calculator displays these values directly when you make your selection – so you can find the right one for your group in seconds.
Can I return the purchase?
Since this is an instant digital download, cancellation is legally excluded once the download has started (§ 356 para. 5 BGB) – this is standard practice for digital content. However, if you have any problems with the files or your computer access, just contact me via Etsy. I'll always find a solution.
