Detailed guide for all core calculator features on surebets.help.
The calculator is built for arbitrage setups, middle windows, and asian handicap lines. Use this section to understand what each result means.
1) Arbitrage (SureBet)
Arbitrage is a stake distribution method where you balance exposure across outcomes to reduce risk.
A clean surebet appears when all main outcomes are positive. Near-arb appears when outcomes are close to break-even.
2) Middle
Middle appears when there is a line window (usually Over line < Under line) where specific outcomes return better profit than base outcomes.
The middle window can target one or two specific results, for example 2 goals and 3 goals.
3) Polish Middle
Polish is the reverse setup (often Over line > Under line) with a risk zone measured through Polish Odds.
If polish is not valid, the calculator shows NO POLISH MIDDLE.
4) Asian Handicap (AH)
AH uses virtual goal advantage or disadvantage. Quarter lines split stake between adjacent lines.
Examples are +0.25 and -0.75 where stake is split in two parts.
- +0.25 = half stake on 0.00 and half stake on +0.50
- -0.75 = half stake on -0.50 and half stake on -1.00
The calculator has three modes with shared recalculation logic but different lines and conditions.
Classic Mode
Uses 1X2 and mixed european or asian line combinations.
Invalid line options are hidden and only valid combinations remain visible.
Total Mode
Uses Over and Under lines for total goals, including quarter lines such as 2.25, 2.75, 3.25, and 3.50.
Depending on line combination, results can be surebet, middle, or polish.
AH Mode
Uses handicap lines for side 1 and side 2 with goal-difference conditions.
Condition labels are like Win by N, Lose by N, or Draw.
Line Format and Odds Type
Line Format changes only visual representation of lines: Decimal or Fraction.
Odds Type supports EU, HK, Malay, and UK, where UK is fractional (for example 19/20, 5/2, evens).
Each mode has a driver stake row or a Total stake driver. Editing the selected driver recalculates dependent fields automatically.
1) Base Stake and Total Stake
- Select a row radio to use that stake as the driver.
- Select Total radio to distribute one total amount automatically.
- In demo mode, Total stake is fixed and locked.
2) Profit Allocation Checkboxes
- One selected checkbox: prioritize that outcome.
- Two selected checkboxes: split allocation between those outcomes.
- All selected or none selected: equal allocation across active outcomes.
3) ROI Colors and Zero Values
- Positive values are green.
- Negative values are red.
- Zero is neutral and must never be shown as -0.00.
4) Safe Stakes
When enabled, automatic stake values are rounded by selected step: 1, 5, 10, 20, 50, or 100.
This affects auto-calculation and manual step controls.
The special result column changes dynamically based on selected lines and mode.
1) Dynamic Titles
- Middle: valid middle window.
- Polish: valid polish window.
- SureBet: standard two-way surebet scenario.
2) Result Boxes and Conditions
- The column has one primary result box.
- A second box appears only when a second unique condition exists.
- Condition labels are mode specific, for example 2 goals or 3 goals in Total, and Win by 1 in AH.
3) Hint Messages under the Boxes
- Middle+Surebet! when both base ROI values are positive.
- Middle Odds: X.XX or Polish Odds: X.XX when valid.
- NO MIDDLE or NO POLISH MIDDLE when invalid.
- For pure surebet cases, the special box can show YES or NO.
