Most arbitrage calculators only handle two outcomes. But the world’s most popular sport, Football (Soccer), has three: Home Win (1), Draw (X), and Away Win (2).
This calculator is designed specifically for 1X2 markets. It helps you find “surebets” where different bookmakers have priced the outcomes so inefficiently that you can bet on all three and guarantee a profit — regardless of which team wins or if the match ends in a draw.

1X2 SurebetWhat is 3-Way Arbitrage Betting?
3-way arbitrage (also called “surebetting” or “arbing”) is a betting strategy where you place bets on all three possible outcomes of a match at different bookmakers to guarantee a profit no matter the result.
This works because bookmakers often disagree on probabilities. When you find the highest odds for each outcome across different bookies, sometimes the combined implied probability drops below 100% — creating a guaranteed profit opportunity.

How 3-Way Arbitrage Works
You need accounts at multiple bookmakers to execute this strategy. You scan the market for the highest odds on each outcome, then calculate if an arbitrage opportunity exists.
The Arbitrage Formula
Arb % = (1/Odds₁) + (1/Odds₂) + (1/Odds₃)
✅ If Arb % < 100% → Profitable arb exists
❌ If Arb % ≥ 100% → No arb (bookmaker margin)
Profit Margin = (1 - Arb %) × 100
Stake = (Total Investment × (1/Odds)) / Arb %
Example: The Perfect Arb
Match: Barcelona vs. Real Madrid (La Liga)
| Outcome | Bookmaker | Odds | Implied Probability |
|---|---|---|---|
| 1 (Home Win) | Bet365 | 2.50 | 1/2.50 = 40.00% |
| X (Draw) | Pinnacle | 3.60 | 1/3.60 = 27.78% |
| 2 (Away Win) | William Hill | 3.80 | 1/3.80 = 26.32% |
| Total Implied Probability: | 94.10% | ||
✅ Arbitrage Found! Profit Margin: 5.90%
Since 94.10% < 100%, this is a guaranteed profit opportunity. With a $100 total stake, you’ll profit approximately $6.27 regardless of outcome.
Stake Breakdown ($100 Total Investment)
| Outcome | Stake | If Wins → Return | Profit |
|---|---|---|---|
| Home Win (Barcelona) | $42.51 | $42.51 × 2.50 = $106.28 | +$6.28 |
| Draw | $29.51 | $29.51 × 3.60 = $106.24 | +$6.24 |
| Away Win (Real Madrid) | $27.98 | $27.98 × 3.80 = $106.32 | +$6.32 |
Result: No matter who wins or if it’s a draw, you profit approximately $6.27 (6.27% ROI).

⚠️ The Risks of 3-Way Arbitrage
While arbitrage betting is mathematically risk-free, several practical risks can turn a guaranteed profit into a loss:
1. Odds Movement
Odds can change between placing your bets. If one leg moves significantly, your arb may disappear or become negative.
Mitigation: Place largest stake first, use odds comparison tools with alerts, act fast.
2. Bookmaker Limits (“Gubbing”)
Bookmakers restrict accounts they suspect of arbing. Max stakes get reduced to unusable amounts (sometimes $1-5).
Mitigation: Round stakes, mix in recreational bets, use multiple accounts, bet at normal times.
3. Palpable Errors (Palps)
If a bookmaker claims “obvious pricing mistake,” they can void your bet — but your other legs remain, causing potential loss.
Mitigation: Avoid odds that seem too good to be true, document everything, check T&Cs.
4. Maximum Stake Limits
Your planned bet may be reduced by the bookmaker, creating an unbalanced arb with potential loss.
Mitigation: Check limits before placing, have backup bookmakers, start with smaller stakes on new accounts.
5. Account Verification Delays
KYC requests can freeze your funds. You can’t place remaining legs while your account is under review.
Mitigation: Complete verification before arbing, keep documents ready, maintain funded accounts.
6. Currency Fluctuations
If betting across bookmakers in different currencies, exchange rate changes can affect your profit.
Mitigation: Use same currency where possible, account for conversion fees in calculations.
🛡️ How to Avoid Bookmaker Detection
Bookmakers use sophisticated algorithms to detect arbitrage bettors. Here’s how to fly under the radar:
| ✅ DO This | ❌ DON’T Do This |
|---|---|
| Round stakes to natural amounts ($42.51 → $40 or $45) | Place exact calculated amounts ($42.51) |
| Bet during normal hours (evenings/weekends) | Bet at 3am on obscure leagues |
| Mix in recreational bets, parlays, casino games | Only place arb bets |
| Withdraw gradually over time | Cash out entire balance after every win |
| Use betting exchanges for larger stakes | Rely only on soft bookmakers |
| Bet on popular markets (EPL, La Liga) | Target only niche/low-liquidity markets |
| Skip obviously mispriced odds | Bet on every “too good to be true” line |
Stake Rounding Strategy
Why Round Stakes?
Bookmakers flag accounts that consistently place unusual amounts like $47.83 or $124.67. Real recreational bettors place round numbers.
Rounded: $40 or $45
Rounded: $125 or $130
Rounded: $30
💡 Pro tip: Small profit reduction from rounding is worth the dramatically lower detection risk. Our calculator includes automatic stake rounding!

Frequently Asked Questions (FAQ)
What is 3-way arbitrage betting?
How do I calculate 3-way arbitrage profit?
1/Odds, then sum them together. If the total is less than 100%, an arbitrage opportunity exists. The profit margin equals 100% minus the total implied probability. For stakes, use: Stake = (Total Investment × (1/Odds)) / Total Implied Probability. For example, with odds of 2.50/3.60/3.80, the total is 94.10%, giving a 5.90% profit margin.
