Over 1.5 Goals at a Glance
Every fixture is scored using a 4-signal weighted model that combines goals per game, shots on target, cross-matchup analysis, and anti-low-scoring filters into an Over Goals Score (OGS) between 0 and 100.
The STRONG signal is currently performing exceptionally well, identifying matches that consistently produce 2 or more goals.
Matches must pass a strict hard filter before being surfaced — no prediction is shown unless the statistical evidence supports it.
What Is the Over 1.5 Goals Feature?
The Over 1.5 Goals feature predicts whether a match will produce 2 or more total goals. It is one of the most popular betting markets in football because it strikes a balance between likelihood and value — most matches produce at least 2 goals, but the ones that do not can be identified statistically.
ScoreSage AI analyses the last 10 completed matches for both teams, calculates a probability score using four weighted signals, and applies strict statistical filters to determine which matches deserve a signal.
How the Scoring System Works
The Over Goals Score (OGS)
Every fixture receives an OGS between 0 and 100. This score is built from four distinct signals, each weighted according to its predictive power:
Signal 1: Goals Per Game (40% Weight)
The heaviest signal. This measures the raw scoring output of both teams, adjusted for venue:
- Home team: Uses home-only averages when 3+ home matches are available
- Away team: Uses away-only averages when 3+ away matches are available
- Expected goals per match = (Home scored + Away conceded + Away scored + Home conceded) / 2
A match between two teams averaging 2+ goals per game gets a strong base score. A match between two teams averaging under 1 goal per game starts much lower.
The venue split matters because some teams score freely at home but struggle away, or vice versa. Using venue-aware data avoids inflating predictions based on misleading combined averages.
Signal 2: Shots on Target Proxy (25% Weight)
Goals are noisy — a team can dominate a match and still lose 1-0 to a counter-attack. Shots on target are a more stable measure of attacking intent and quality.
This signal measures the combined average shots on target per game for both teams. When SOT data is unavailable, the system estimates it using a goals-to-shots ratio (approximately 3.5 shots per goal).
High SOT numbers indicate teams that are consistently creating quality chances, which tends to produce goals over larger samples even when individual matches defy the pattern.
Signal 3: Cross-Matchup Interaction (20% Weight)
This signal looks at how the specific matchup works, not just each team in isolation:
- Home Attack vs Away Defence: How strong is the home team's attack compared to the away team's defensive record?
- Away Attack vs Home Defence: How strong is the away team's attack compared to the home team's defensive record?
The cross-matchup score is the geometric mean of these two ratings. This means both attacking vs defensive matchups need to be favourable — one strong attack facing a strong defence is not enough.
Signal 4: Anti-Low-Scoring Filter (15% Weight)
The final signal penalises teams with a history of under 1.5 goal matches:
- Measures the percentage of each team's last 10 matches that finished with 0 or 1 total goals
- A team where 40% of matches are under 1.5 gets a significant penalty
- A team where only 10% are under 1.5 gets almost no penalty
This acts as a safety check — even if goals per game and SOT look good, a high under 1.5 rate suggests the team is involved in enough low-scoring matches to be cautious.
How the Signals Combine
The four signals are weighted and combined:
OGS = 40 + ((0.40 x Goals Signal + 0.25 x SOT Signal + 0.20 x Cross Signal + 0.15 x Anti-Low Signal) x 60)
The base of 40 ensures that even average matches get a non-trivial score, while the 60-point range above it is where the signals differentiate strong picks from weak ones.
Signal Strengths Explained
ELITE Signal (OGS 88+)
The highest confidence level. An ELITE signal means the match has passed every statistical check with room to spare:
- Both teams average 1.0+ goals per game OR have scored in 8+ of their last 10 matches
- At least one team concedes 1.0+ goals per game — there is defensive vulnerability present
- Combined average of 2.5+ goals per game across both teams
- Under 1.5 rate of 25% or below for both teams — low-scoring matches are rare
- Combined average of 7+ shots on target per game (when SOT data is available)
- OGS score of 88 or above
ELITE signals are rare but represent the strongest possible statistical case. Every metric is aligned.
STRONG Signal (OGS 70-87)
The STRONG signal is currently the standout performer across all Over 1.5 predictions. It represents:
- All hard filter criteria met — the same strict checks as ELITE, validated
- OGS score between 70 and 87 — strong evidence from the 4-signal model
- Consistent goal-scoring patterns from both teams across recent matches
STRONG is the sweet spot for most users. The statistical foundation is solid, the hard filter confirms data quality, and the volume is higher than ELITE alone — meaning more actionable opportunities each day.
The current performance data shows STRONG signals hitting at an excellent rate, making this tier the primary focus for users building a consistent Over 1.5 strategy.
ABOVE AVERAGE Signal (OGS 65-69)
These signals pass a relaxed filter with slightly reduced thresholds:
- Requirements are approximately 80% of the hard filter thresholds
- Head-to-head validation — the system checks whether this specific fixture historically produces 2+ goals (40%+ threshold)
- OGS score between 65 and 69
ABOVE AVERAGE signals are useful for research and building shortlists but carry more uncertainty than STRONG or ELITE picks.
No Signal (Filtered Out)
Matches that fail both the hard and relaxed filters are not displayed. This is by design — showing every match with a score would dilute the quality of the signals that matter.
How to Use the Feature Properly
1. Focus on STRONG as Your Core
Given current performance data, STRONG signals should be the backbone of your Over 1.5 approach. They provide:
- Statistically validated evidence (hard filter passed)
- A meaningful probability score (70+)
- Enough daily volume to build a consistent strategy
- An excellent recent hit rate
ELITE signals are a bonus when they appear, but their rarity means you cannot rely on them alone.
2. Understand What Is Driving the Score
Every signal includes a breakdown of the four weighted components. Pay attention to:
- Is the score carried by one signal or spread across all four? A match where all four signals are strong is a better prospect than one carried entirely by high goals per game but low SOT
- How strong is the cross-matchup? Two good attacks facing two weak defences is the ideal scenario. One good attack facing a strong defence is less convincing
- What is the under 1.5 rate? Even with high OGS, a team with 30%+ under 1.5 rate introduces variance
3. Check the Venue Split
The system uses venue-aware data, but it is worth understanding why:
- A team averaging 2.5 goals per game overall might average 3.2 at home and 1.8 away
- If they are playing away, the 1.8 figure is more relevant
- The OGS already accounts for this, but knowing which direction the adjustment goes helps you assess the signal
4. Layer With Context
The statistical model does not know about:
- Key absences — a team missing their main striker changes the attacking calculus
- Tactical motivation — a team already relegated may play more openly (more goals) or give up (fewer goals)
- Derby matches — these can be tighter and more cautious than the stats suggest
- Cup competitions — some managers rotate squads, affecting quality
Use these factors to upgrade or downgrade your confidence in the statistical signal.
5. Track Performance by League
Not all leagues behave the same way. Some leagues (Bundesliga, Eredivisie) tend to produce more goals than others (Serie A, Ligue 1 historically). The Records page lets you filter results by league and tier, helping you identify where the model performs best.
6. Manage Stakes Consistently
Over 1.5 goals is one of the higher-probability markets, which means odds tend to be lower. The edge comes from consistency over volume, not from individual high-odds wins. Use flat or percentage-based staking rather than chasing returns on single matches.
The 4-Signal Model in Practice
Here is an example of how an OGS score is built:
Match: Team A (Home) vs Team B (Away)
| Metric | Team A (Home) | Team B (Away) |
|---|---|---|
| Goals per game (venue-adjusted) | 2.1 | 1.4 |
| Goals conceded per game | 1.3 | 1.6 |
| Avg SOT per game | 5.2 | 4.1 |
| Under 1.5 rate | 15% | 20% |
| Attack rating | 0.78 | 0.61 |
| Defence rating | 0.58 | 0.47 |
Signal calculations:
- Goals Signal (40%): Expected goals = (2.1 + 1.6 + 1.4 + 1.3) / 2 = 3.2 → normalised = 3.2 / 3.0 = 1.0 (capped) → 1.0
- SOT Signal (25%): Combined SOT = 9.3 → normalised = 0.83
- Cross Signal (20%): Home attack vs Away defence = 0.78 x 0.47 adjusted, Away attack vs Home defence = 0.61 x 0.58 adjusted → geometric mean = 0.72
- Anti-Low Signal (15%): 1 - ((15 + 20) / 200) = 0.825
Combined = (0.40 x 1.0) + (0.25 x 0.83) + (0.20 x 0.72) + (0.15 x 0.825) = 0.875
OGS = 40 + (0.875 x 60) = 92.5 → ELITE
All four signals are strong, the hard filter passes easily, and the combined score earns the highest tier.
Why Over 1.5 Goals Is a Reliable Market
High base rate: Across major European leagues, roughly 75-80% of matches produce 2 or more goals. The model's job is to identify the 85-95% probability matches and avoid the 50-60% ones.
Stable statistics: Goals per game and shots on target are among the more stable football statistics over 10-match samples. This gives the model reliable inputs.
Early settlement: Many Over 1.5 matches are settled well before full time — once the second goal goes in, your bet is won regardless of what happens next.
Wide availability: Over 1.5 goals is offered by every major bookmaker with competitive odds and high liquidity.
