Norfolk Island guide to football markets and probability
Work out what would settle a selection before considering how likely it appears. These examples distinguish three-way results, combined goals and goals from both teams. The final calculation explains the role of a reference price without presenting an illustrative number as a prediction for an actual match.
A row belongs to the UTC day of its match’s kickoff, even if the selection was published at another time. When checking tomorrow, confirm that the active match date is the UTC day you intended rather than inferring it from when the page opened. The dated links move between selected match days. A table contains published selections in its market, not every scheduled fixture. It may load without rows when no selections are available for that day and market. If retrieval fails, a separate error message describes a data problem. That failure does not establish the same thing as a loaded empty list.
Imagine the market’s period ending at 2–2. The 1X2 outcome is X because the home and away scores are level, regardless of what a later tie-break might decide. If the home side is ahead, the result is 1; if the visiting side is ahead, it is 2. Those three outcomes are mutually exclusive within the specified period. Read a qualification selection separately, and recognise that double chance permits a pair of outcomes instead of representing the same condition as one 1X2 result.
An over 2.5 selection is settled by the sum of the two scores over the specified period. Four goals at 4–0 exceed the threshold even though the away team has not scored; a 2–1 result reaches it with three goals and both sides contributing. Three is the first whole-goal tally above 2.5. The condition does not identify the winner or demand BTTS Yes. Any combined selection that adds those requirements must be assessed using all of its conditions, rather than the total alone.
A 1–0 score falls under 2.5, but so does 0–1 with the opposite winner. The accepted combined counts are zero, one and two; a third goal moves the total beyond the line. Two goals in a 1–1 score show why a low total can coexist with BTTS Yes. Keep the period attached to the market while adding the goals. There is no extra requirement for a home win, an away win or a scoreless team unless the selection explicitly says so.
Knowing who scored first is not enough to resolve BTTS. Yes needs a goal from each of the two teams within the stated period, while No means at least one team has no goal in that period. Thus 3–1 answers Yes and 3–0 answers No; the winning side is unchanged but the scoring contribution is different. BTTS should also remain distinct from a goal-total threshold. If a selection combines them, each condition has to be met rather than letting one successful part stand for the whole.
A recorded reference price lets you reconstruct the comparison made at publication. As a numerical illustration, decimal odds of 3.50 give an unadjusted reciprocal of about 28.57%; this is not an estimate for a named fixture. Market-derived estimates account for the margin across the relevant outcomes, not through a fixed deduction from one decimal price. A later accepted price can differ from the recorded reference and change the comparison. The highest estimated chance does not necessarily offer the strongest value at its available price.
Both teams to score means each team must score at least one goal in the specified period. The match winner does not matter.
A likely outcome. A good price?
Probability and price answer different questions. A likely outcome can still be poorly priced. Estimated value compares the price with a reference probability; it is not a promise of profit.
Over 2.5: count the goals.
Over 2.5 requires at least three goals in total in the specified period. Two goals or fewer is Under 2.5. Check the market period and bookmaker settlement rules.
A worked example: probability and price
Illustration only: a 60% estimate implies fair decimal odds of about 1.67. At 1.50 the price is below that estimate’s break-even point; at 1.80 it is above it. The estimate can be wrong. Neither price makes a win certain, and the available price can change after publication.
Read the record, not just the hit rate
A method can win more bets than it loses and still lose money at short odds. Read ROI alongside settled sample size and maximum drawdown. Results use a flat one-unit reference stake, not a recommendation to bet every selection. Markets on the same match are correlated.
Before following a selection
Confirm the teams, market, period and current odds on the bookmaker’s site. A published quote is a snapshot, not a reserved price. Decide your limit before you play; do not increase it to chase a loss. You can always skip a selection.
