Two types of arbitrage this scanner finds

Intra-bookmaker (same bookmaker, cross-market) — Two different markets on the same match within one bookmaker whose combined outcomes cover all results. Example: 1xBet's 1X2 Home Win + 1xBet's Double Chance X2.
Inter-bookmaker (same match, different bookmakers) — The same outcome type (e.g. 1X2) on the same match, but priced differently across Pinnacle, William Hill, 1xBet etc. You back each outcome with the bookmaker giving the best price.

The Formula (same for both)

Sum = (1/Odd₁) + (1/Odd₂) + (1/Odd₃...)

If Sum < 1.00 → arbitrage exists
Profit% = (1 − Sum) × 100

Stake split formula

Stake on outcome N = (1/OddN) ÷ Sum × Total stake

Enter your total amount in the stake field. The calculator splits it correctly across all legs — guaranteed same return regardless of result.

Intra-book market combinations checked

1X2 Home Win + Double Chance X2 → covers all 3 results
1X2 Away Win + Double Chance 1X → covers all 3 results
1X2 Draw + Double Chance 12 → covers all 3 results
Over 2.5 + Under 2.5 → covers all scorelines
Full 1X2 3-way → all results

Note: The Odds API's free tier returns h2h and totals markets. Double Chance and BTTS require the doubleChance market which is a paid feature, so intra-book arb is limited to h2h + totals combinations for now.

API quota management

The free tier gives you 500 requests/month. Each sport + market combination costs 1 request. This scanner fetches h2h + totals = 2 requests per scan. At 2 requests per scan you get 250 scans/month — about 8 scans per day. Use Auto-refresh wisely.

EU Region Bookmakers (best for Nigeria)

These are the bookmakers whose odds are compared. The more bookmakers price a match, the more arb opportunities exist.

Which region should I use?

For Nigeria, EU region is best — it includes 1xBet and Pinnacle which are both popular here and tend to have the widest odds differences, giving the most arb opportunities. The UK region also produces good arb because of the large number of competing bookmakers.
