3-way arbitrage explained
A 3-way arbitrage covers the classic 1X2 market: Home win, Draw, or Away win. Full-time football is the textbook case. Because the three best prices usually live at three different bookmakers, combining them lets you cover all results and still guarantee a return.
Worked example
Suppose the best available odds are Home 2.70, Draw 3.40 and Away 3.10. The sum of inverses is 1/2.70 + 1/3.40 + 1/3.10 ≈ 0.985 — under 1, so a surebet exists. Enter the three odds above with your stake and the calculator allocates each bet for an even, guaranteed profit.
Why 3-way arbs take a little more work
Three-way markets (1X2) carry a higher built-in margin than two-way ones — the bookmaker's overround is spread across three prices, so surebets are rarer and usually thinner (often 1–2%). Two practical points:
- The draw is the awkward leg. Draw prices drift less predictably than Home/Away, so the best draw odds often sit at a different bookmaker than the two win prices — you'll typically need three books for one 1X2 arb.
- Can't find a full 3-way? "Draw No Bet" turns the same match into a two-way market (stake returned on a draw), which is often easier to arb than the full 1X2.
Beyond full-time football, other 3-way markets include full-time result in handball and any regular-season format that allows a tie.
Reading the 1X2 overround
Add up the implied probabilities of a single bookmaker's Home, Draw and Away prices and you'll almost always get a total above 100% — say 105–108%. That surplus is the margin. A 3-way surebet exists only when the best Home, Draw and Away prices across different bookmakers combine to under 100%. Enter all three above and the calculator's V value shows instantly whether you've beaten the overround.

Frequently asked questions
- What is a 3-way arbitrage bet?
- A 3-way arb covers a market with three outcomes — typically Home, Draw and Away (1X2) — so that any of the three results returns a profit.
- Why are football matches 3-way?
- Standard full-time football betting has three results: home win, draw, or away win. That is why the 1X2 market is a classic 3-way arbitrage opportunity.
- Do I need three different bookmakers?
- Usually yes — the best price on each of the three outcomes often sits at a different bookmaker, and combining them is what creates the surebet.
