The 'Treacherous' Banker
Choosing a banker based only on low odds (e.g., 1.20). If that match ends 0-0, you've thrown away a perfect system on the other 9 matches.
Reduced Systems
The power of mathematics at the service of savings. Play complex systems with many matches by cutting costs through N-1 reductions and strategic use of 'Bankers'.
What is a Reduced System?
A reduced system is a subset of an integral or error correction system. Instead of playing ALL possible combinations (which are expensive), the reduced system selects only a part of them, still guaranteeing a win (e.g., at least one N-1 win) if the set conditions are met. It is the preferred tool for professional system players to manage 10-20 matches at once.
"Maximum yield, minimum expense: the reduced system allows you to dream of a big hit on many matches while paying only a fraction of the price of a full system."
In an N-1 reduced system, if you hit all your predictions (N), you have a mathematical guarantee of winning at least one slip with one less error. If you hit 6 out of 6 in an N-1 reduced for fives, you will surely win at least one 5-fold slip. Often, by mathematical luck, you still hit the full column (N), but the cost savings are guaranteed.
To further lower the cost, bankers (Fisse) are used. A banker is an event that MUST be correct for the entire system to stay alive. If the banker is correct, the reduced system develops on the other matches. If the banker fails, the entire system is lost. It is a necessary compromise to play many combinations with just a few euros.
Modern software uses 'block' or 'orthogonal' reduction algorithms to cover the maximum number of combinations with the minimum number of columns. This allows for risk optimization and spreading the winning probabilities across different prize tiers (e.g., multiple wins for 4 or 5 errors).
| System | Matches | Columns | Cost (€0.50/col) | Guarantee |
|---|---|---|---|---|
| 6 out of 8 System | 8 | 28 | €14.00 | Full |
| N-1 Reduced (8) | 8 | 8 | €4.00 | N-1 (6-fold) |
| Reduced w/ 2 Bankers | 2+6 | 3 | €1.50 | Bankers + N-1 |
| Savings | Up to 90% | N/A | N/A | Mathematical |
| Situation | Full System | Reduced System |
|---|---|---|
| Unlimited Budget | Yes, for max win | No |
| Many Matches (8+) | No, too expensive | Yes, mandatory |
| Low Confidence in Bankers | Yes | No, risky |
| Savings Goal | No | Yes, method core |
Don't be fooled by the low cost
Ignoring Reduction Probabilities
Thinking the reduced system is the same as a full system. Remember that if you hit everything, you might not get the 'full' win but only the minimum guaranteed win.
Infinite Development
Exaggerating the number of variable matches. Even with reduction, if you put 20 matches and hit only 5, you won't win anything.
The banker must be the match you have absolute maximum confidence in, not just the lowest odds.
Always check how many columns the software generates so you don't exceed your preset budget.
Reduced systems work best with average odds (1.80+) to compensate for fewer winning columns.
