How it works
Fewer combinations, guarantee by design
An integral system plays every possible combination of a number group: full coverage, but cost grows fast. A reduced system instead selects a subset of combinations chosen so that, if the drawn numbers are among those played, a minimum win is guaranteed by design.
G3/G4/G5 marks the guarantee level: G3 ensures at least a triple, G4 at least a quadruple, G5 at least a quintuple — provided the required count of numbers is drawn among those in the system. Cutting combinations by up to ~75% versus the integral, cost drops sharply for the same guarantee.
Guarantee levels
Illustrative reduction scheme. The guarantee holds only if the required numbers are drawn among those in the system.
How the guarantee is built (combinatorial coverage)
An integral system on n numbers plays all C(n, k) combinations of k numbers: full coverage but cost grows fast. A reduced system is a combinatorial covering: the minimal subset of combinations such that every group of numbers in the guaranteed "category" is contained in at least one played combination.
G3 example: if 3 of the drawn numbers fall in your group, there is — by construction — at least one system combination containing all three. The guarantee is a property of the design, verifiable on paper before playing, not a prediction.
Note: the guarantee is about which type of win you get if the right numbers are already in the system. It does not raise the probability they are drawn and does not move the expected value, which stays negative.
Shared play
The same system split across players
With shared play a system can be split across several players: each covers a share of the combinations and costs, while the group keeps the overall guarantee. It's the way to access large systems with a small per-person cost.
Shares are managed by the platform transparently: everyone pays and receives their own part, with no pot handed to an organiser who could disappear with the group's money. And there's no obligation to buy the whole system — you join only for the shares you choose.
- Guarantee by design: the minimum win doesn't depend on luck on a single line
- Up to −75% fewer combinations than the integral system
- Choose the guarantee level: G3 (triple), G4 (quadruple), G5 (quintuple)
- Shared play across participants: costs and combinations split, group guarantee
- Shares managed by the platform: no pot entrusted to an organiser
- No obligation to buy the whole system: join only for the shares you want
What a reduced system does NOT do
The guarantee is about the win type when the right numbers are already in the system: it does not increase the probability those numbers are drawn, nor make the game profitable. The game's expected value (EV) stays negative.
