Surebet detector and ποντάρισμα calculator
How this calculator works
A surebet (also called an arb) occurs when the combined implied probabilities across all outcomes in a αγορά fall below 100%. By distributing a ποντάρισμα across each outcome in proportion to their implied πιθανότητα, you guarantee a κέρδος regardless of result.
For a 2-way αγορά: arb% = (1/o1) + (1/o2). For a 3-way αγορά: arb% = (1/o1) + (1/o2) + (1/o3). If arb% is less than 1.00, a surebet exists.
Ποντάρισμα allocation for each outcome: ποντάρισμα_n = (total x (1/αποδόσεις_n)) / arb%. This ensures that every outcome pays out the same total amount: total / arb%. The guaranteed κέρδος is (total / arb%) - total.
For example: o1 = 2.20, o2 = 2.10, o3 = 3.60. Arb% = 0.4545 + 0.4762 + 0.2778 = 1.2085. This is above 1.00, so no surebet exists. But if o3 were 5.00, arb% = 0.4545 + 0.4762 + 0.2000 = 1.1307, still no surebet. For a surebet on a 3-way, you typically need all three outcomes to be generously priced simultaneously.
Finding surebets requires comparing prices across multiple bookmakers simultaneously. Real-time discrepancies are uncommon and short-lived because bookmakers adjust rapidly. The most common genuine surebets arise from promotional boosts or error prices that are slow to correct.
The calculator does not apply commission deductions. If one leg is placed at a betting exchange, the lay commission (typically 2-5%) must be factored in to determine whether the net surebet still holds. See the αγώναςed bet calculator for commission-aware calculations.

Συχνές Ερωτήσεις
How often do real surebets occur?
Genuine surebets across reputable bookmakers are rare and disappear within minutes of appearing. They are more common during major γεγονότα when multiple bookmakers compete and errors or boosts create temporary discrepancies.
What is the minimum arb% that makes a surebet worthwhile?
Any arb% below 100% (less than 1.00 in decimal form) is technically κέρδοςable. However, after λογαριασμό for ελάχιστο ποντάρισμα rounding and time cost, most arbers target at least 1-2% guaranteed κέρδος margin.
Do I need accounts at multiple bookmakers?
Yes. Surebets arise from price discrepancies between different bookmakers. A single bookmaker cannot offer a surebet against itself in a standard αγορά.
Can I use this for in-play markets?
Yes, but in-play αγορές move quickly. You must be able to place both bets almost simultaneously. Price changes between placements can eliminate the arb or even create a loss.
Is surebet betting legal?
Surebet betting is legal but some bookmakers restrict λογαριασμόs identified as arbers. Always check terms and conditions and be aware of potential ποντάρισμα limits.
