First Half Goals at a Glance
ScoreSage AI analyses the last 10 matches for both teams to calculate a First-half Probability Score (FPS) between 0 and 100, then assigns a signal strength based on the weight of evidence.
The STRONG signal is currently performing exceptionally well, consistently identifying matches where first-half goals arrive.
Only matches that pass a strict statistical filter are shown — if the data does not support a prediction, no signal is generated.
What Is the First Half Goals Feature?
The First Half Goals (FHG) feature is a pre-match prediction tool that answers one question: will at least one goal be scored in the first half of this match?
It is not a guess. Every prediction is built from a statistical analysis of both teams' recent first-half scoring and conceding patterns. The system examines the last 10 completed matches for each team, extracts halftime-specific data, and calculates the probability of a first-half goal occurring.
Matches where the evidence is weak are filtered out entirely. You only see fixtures where the data actively supports the prediction.
How the Scoring System Works
The First-half Probability Score (FPS)
Every analysed match receives an FPS score between 0 and 100. This score represents how likely a first-half goal is based on four key factors:
1. First-Half Attack Strength (per team)
How often does each team score in the first half? The system looks at halftime scorelines from each team's last 10 matches and calculates a normalised attack rating on a 0-1 scale.
A team that scores in the first half of 8 out of 10 matches has a high attack strength. A team that regularly goes into half time at 0-0 has a low one.
2. First-Half Defensive Leakiness (per team)
How often does each team concede before half time? This is the defensive mirror of attack strength — a team that concedes first-half goals frequently makes it more likely their opponent will score early.
3. Cross-Team Probability
The system combines each team's attacking ability with the opposing team's defensive vulnerability:
- Home team's first-half scoring chance = (Home Attack Strength + Away Defensive Leakiness) / 2
- Away team's first-half scoring chance = (Away Attack Strength + Home Defensive Leakiness) / 2
The probability that at least one first-half goal occurs is then calculated as:
P(FHG) = 1 - (1 - Home Scoring Chance) x (1 - Away Scoring Chance)
This means both teams contribute to the prediction — even if one side is defensively solid, a highly attacking opponent can still push the probability up.
4. Recent Form Weighting
The last 5 matches are given slightly more weight than matches 6-10, reflecting the reality that recent form is a stronger predictor than older results.
What the FPS Number Means
| FPS Score | Interpretation |
|---|---|
| 90-100 | Extremely high probability — both teams consistently involved in first-half goals |
| 70-89 | Strong evidence — clear first-half scoring patterns from both sides |
| 65-69 | Above average — some evidence, but not overwhelming |
| Below 65 | Filtered out — not enough evidence to surface a prediction |
Signal Strengths Explained
The FPS score is only half the story. Before a match is shown to you, it must also pass a hard filter — a set of strict statistical checks that validate the underlying data quality.
PERFECT Signal (FPS 90+)
The highest confidence level. A PERFECT signal means:
- First-half goal involvement in 7+ of the last 10 matches for both teams — both sides consistently feature in first-half scoring
- First-half scoreless rate of 30% or below — fewer than 3 in 10 matches go to half time at 0-0
- Combined average of 0.8+ first-half goals per game — when these two teams play, first-half goals are the norm, not the exception
- FPS score of 90 or above — the probability model confirms what the filters show
PERFECT signals represent the strongest possible statistical case for a first-half goal.
STRONG Signal (FPS 70-89)
The STRONG signal has been performing exceptionally well and is where many of the best opportunities sit. A STRONG signal means:
- All hard filter criteria are met — the same strict checks as PERFECT, just with a slightly lower probability score
- FPS score between 70 and 89 — strong statistical evidence from both teams
- Clear first-half scoring patterns — the data consistently shows these teams are involved in early goals
The STRONG tier is the sweet spot for many users. The statistical evidence is robust, the hard filter confirms the data quality, and the volume of signals is higher than PERFECT alone — giving you more opportunities to work with.
ABOVE AVERAGE Signal (FPS 65-69)
A step below STRONG, these signals pass a relaxed filter with slightly looser requirements:
- First-half goal involvement in 6+ of the last 10 matches (relaxed from 7)
- First-half scoreless rate of 40% or below (relaxed from 30%)
- Head-to-head validation — the system checks whether this specific fixture historically produces first-half goals (50%+ threshold)
- FPS score between 65 and 69
ABOVE AVERAGE signals are viable but carry more uncertainty. They are best used as part of a broader research process rather than standalone picks.
No Signal (Filtered Out)
If a match fails both the hard filter and the relaxed filter, it is not shown at all. This is deliberate — no signal is better than a weak signal.
How to Use the Feature Properly
1. Prioritise STRONG Signals
Given the current performance data, STRONG signals are the primary action zone. They combine robust statistical evidence with a high enough volume of daily picks to build a consistent approach.
PERFECT signals are excellent when they appear, but they are rarer. Building a strategy around STRONG + PERFECT gives you the best balance of quality and quantity.
2. Read the Breakdown
Every signal comes with a detailed breakdown showing:
- Each team's FH attack strength — who is driving the prediction?
- Each team's FH defensive leakiness — is one side particularly vulnerable?
- FH scoreless rate — how often do these teams produce goalless first halves?
- Recent form indicators — is the trend improving or declining?
Use this information to validate the signal. A match where both teams have high attack strength AND high defensive leakiness is a stronger case than one carried by a single metric.
3. Consider the Context
The statistical model does not account for:
- Late team news — a surprise striker absence can change the picture
- Tactical context — cup matches, dead rubbers, and relegation battles affect how teams approach the first half
- Weather conditions — heavy rain or extreme heat can slow the pace of play
Layer your own knowledge on top of the statistical signal.
4. Track Your Results
The FHG Records page shows the historical accuracy of each signal tier. Use this to:
- Confirm which tiers are performing best in the current period
- Identify whether certain leagues produce more reliable first-half goal signals
- Adjust your approach based on observed results, not assumptions
5. Manage Your Stakes
Even the strongest statistical signals lose sometimes. First-half goal markets can be volatile — a dominant team might create 5 clear chances and not score until the 50th minute.
Use consistent, disciplined staking. The edge from STRONG signals compounds over time, not on any single match.
Why First-Half Goals Are a Strong Market
First-half goal markets are popular for good reason:
Predictability: Teams that consistently score early tend to keep doing so — first-half scoring is one of the more stable statistical patterns in football.
Data quality: Halftime scorelines are unambiguous. There is no debate about whether a goal was scored — the data is clean and reliable.
Settlement speed: You know the result at half time, not after 90+ minutes. This allows faster feedback and quicker bankroll turnover.
Market availability: First-half goal markets are widely offered by bookmakers with competitive odds.
What the Data Looks Like in Practice
Here is an example of how a STRONG signal is constructed:
Match: Team A (Home) vs Team B (Away)
| Metric | Team A | Team B |
|---|---|---|
| FH goals scored (last 10) | 7/10 matches | 8/10 matches |
| FH goals conceded (last 10) | 6/10 matches | 7/10 matches |
| FH scoreless rate | 20% | 10% |
| FH attack strength | 0.72 | 0.81 |
| FH defensive leakiness | 0.65 | 0.74 |
Calculation:
- Home scoring chance: (0.72 + 0.74) / 2 = 0.73
- Away scoring chance: (0.81 + 0.65) / 2 = 0.73
- P(no FH goal) = (1 - 0.73) x (1 - 0.73) = 0.073
- P(FH goal) = 1 - 0.073 = 0.927
- FPS Score: 96 (PERFECT)
Both teams attack well in the first half, both concede regularly before half time, and the combined probability is extremely high. This is a textbook high-confidence signal.
