Case Study: A Real Sure Bet Walkthrough from Our Board

Three Nigerian bookmakers disagreeing on a three-way result market, worked through end to end -- showing how the concepts across this whole series fit together in practice.

Rather than a purely theoretical example, walking through an actual opportunity type that regularly appears on the My Sure Odds board helps show how all the concepts covered throughout this blog series — implied probability, stake splitting, rounding, and execution timing — come together in practice.

Setting the scene

Consider a domestic league football match where two Nigerian bookmakers are pricing the three-way result market differently enough to create a genuine arbitrage gap. One bookmaker, based on its own trading model and customer betting patterns, prices the home win more conservatively than a competitor; that same competitor prices the away win less conservatively than a third bookmaker offering the best price on the draw. None of the three bookmakers individually has a mispriced market by their own standards — the opportunity exists purely because their independent views, compared against each other, happen to leave a gap.

Reading the board

On the platform, this shows up as a flagged opportunity: the specific match, the three bookmakers involved, the odds being compared for each outcome, and the combined implied probability — say, 97% in this example, representing a roughly 3% guaranteed margin before accounting for rounding.

Working through the stake split

For a total stake of, say, ₦100,000, the platform calculates the proportional split across the three outcomes based on each outcome's implied probability relative to the 97% total — following the same formula covered in the sure-bet calculation post — and rounds each stake in the direction that protects the smallest-margin outcome, rather than naive rounding that could erode the edge.

Executing across three bookmaker accounts

This is where speed matters most: placing all three legs of the bet before any of the three prices moves meaningfully from what was shown on the board. Because the platform's odds are read continuously and the opportunity is fresh, the window to act is typically measured in minutes rather than seconds — but re-verifying each price immediately before confirming each bet, rather than assuming the board's snapshot is still perfectly current by the time all three bets are placed, remains good practice regardless.

The outcome, regardless of the match result

Once all three legs are placed correctly, the specific result of the match becomes irrelevant to the outcome of this particular trade — home win, draw, or away win, the combined payout across the three bookmakers exceeds the ₦100,000 staked, by roughly the calculated margin (accounting for whatever small rounding adjustment was necessary).

What this walkthrough illustrates

The mechanics themselves aren't complicated once broken down step by step — the actual difficulty in arbitrage betting isn't the math, it's consistently finding these gaps across enough matches and bookmakers to matter, and executing them accurately and quickly enough that the calculated margin survives contact with real-world price movement and rounding. That's the specific gap a continuously-running scanner is built to close, turning what would otherwise be a slow, manual, error-prone process into something that can be done reliably and repeatedly.
