Every day, thousands of games are played around the world. NBA, NHL, soccer, tennis — the betting opportunities are endless, but so are the traps. How do you know which game genuinely offers value? How do you avoid the emotional biases that cause 95% of bettors to lose money over the long run?
That is exactly the question ProbWin has been built to answer since 2024. Our platform uses AI models trained on hundreds of thousands of matches to identify positive expected value bets — those where the true probability exceeds the implied probability baked into market odds.
Unlike traditional tipsters, our AI analyzes dozens of statistical variables per game: recent performance, advanced metrics (xG, pace, Corsi, GSAx), injuries, home-field advantage, line movement, and more. The result? Objective, traceable, verifiable predictions.
This guide walks you through everything: from creating your free account to reading a game analysis page like a pro.

Understanding a ProbWin Game Page

The game page is the heart of the ProbWin experience. This is where our AI delivers its verdict. Here is what you will find:
The Confidence Score
Every prediction comes with a confidence score expressed as a percentage. This score reflects how certain the model is in its prediction:
Example — NBA Totals
Game: Lakers vs Celtics
Prediction: OVER 221.5
Confidence: 78%
Edge: +6.2%
Status: OFFICIAL PICK
The higher the score, the more convinced the model is. Only games that exceed a strict confidence threshold become official picks. The rest remain visible as "AI trends."
The AI Detailed Analysis
Below the score, you will find the analysis written by our AI. This is not a simple statistical summary — it is a structured argument explaining why the model reached this decision. For basketball, for example, the AI uses the Game Script method: it projects the game's flow quarter by quarter (Q1 to Q4), estimating pace and tactical adjustments.

The Line Movement Chart
Every game page includes an interactive chart that tracks how odds have moved since opening. If the line shifts in the direction of our pick, it is an additional signal that sharp bettors are on the same side.
The Key Factors
The AI identifies and highlights the deciding factors for each game:
- Major injuries: confirmed absences and their estimated impact
- Recent form: trend over the last 5 to 10 games
- Advanced metrics: xG (soccer), pace (NBA), Corsi/GSAx (NHL), surface stats (tennis)
- Head-to-head history and special conditions (back-to-back games, fatigue, travel)
Markets Analyzed by Sport
ProbWin covers 4 major sports with markets specific to each. Our AI does not spread itself thin: it focuses on markets where it has demonstrated a proven statistical edge.
| Sport | Markets Analyzed | Leagues Covered | Key Metrics |
|---|---|---|---|
| NBA | Spreads, Totals (Over/Under) | NBA | Pace, Off/Def Rating, Game Script |
| NHL | Moneyline, Totals | NHL | Corsi, GSAx, confirmed goalie |
| Soccer | Over/Under 2.5, BTTS, Asian Handicap | Premier League, Bundesliga, La Liga, Serie A, Ligue 1 | xG, OSXG, shots on target |
| Tennis | Moneyline, Total Games | ATP, WTA | Surface stats, ranking, recent form |
Each sport has its own pipeline of specialized AI agents. To understand the different bet types in detail, read our Moneyline, Spread, and Totals guide.
Sport-by-Sport Breakdown
NBA — Spreads and totals. The model uses the Game Script method to project the score quarter by quarter, accounting for pace, injuries, and blowout dynamics. Browse today's NBA predictions.

NHL — The model leverages confirmed goalie data and advanced metrics (Corsi, GSAx) to identify undervalued games. A goalie gate blocks analysis entirely when the starter has not been confirmed. Browse NHL predictions.
Soccer — 5 European leagues, 4 markets. The V5 model uses expected goals (xG) and OSXG for maximum precision. Automatic hard gates block high-risk bets that historically lose. Browse Soccer predictions.
Tennis — Surface-specific matchups, adjusted rankings, serve/return statistics. Odds compared against Pinnacle, the sharp market reference. Browse Tennis predictions.
Official Pick vs AI Trend: What Is the Difference?
This is a fundamental distinction on ProbWin. Not every analyzed game becomes an official pick.
| Criterion | Official Pick | AI Trend |
|---|---|---|
| Confidence | Above sport threshold (65-85%) | Below threshold |
| Edge | Positive and significant | Weak or marginal |
| Validation | Passed through Executor (quality control) | Not validated |
| Displayed | On sport page + alert | Match page only |
| Tracked | Counted in our results | Not counted |
| Access | PRO (or free trial) | Free for everyone |
Why This Distinction Exists
Our AI analyzes every game on the schedule, not just the ones it recommends. For each game, it calculates a confidence score and an edge. But we only publish an official pick when all conditions are met:
- The model exceeds the configured confidence threshold for that sport
- The edge is significant (the perceived value justifies the risk)
- The pick passes Executor filters (verification against known losing patterns)
- No blocking condition is detected (e.g., unconfirmed goalie in NHL, missing data)
AI trends remain visible as a directional indicator. They show you what the model "thinks" about the game even when it is not convinced enough to make it an official pick. That is useful information, but not a betting recommendation.
How to Use Both in Practice
Beginner bettors should focus exclusively on official picks. This is the platform's most reliable signal. AI trends are better suited for advanced bettors who want to cross-reference ProbWin data with their own analysis.
How to Read the Edge on ProbWin
The edge is arguably the most important number on ProbWin. It measures the gap between the probability estimated by our model and the probability implied by market odds. In other words: it is your advantage over the bookmaker.
Example — NHL Moneyline
Game: Canadiens vs Maple Leafs
Our probability: 68.5%
Market probability: 55.2% (odds 1.81)
Edge: 68.5% - 55.2% = +13.3%
→ The model estimates the market
undervalues the Canadiens by 13.3 percentage points.
Why the Edge Is Critical
A profitable bettor does not try to "predict the result" — they try to identify market errors. The edge is the foundation of value betting. Over the long run, consistently betting on positive edges is the only mathematically sound winning strategy.
Edge Display by Sport
The edge is displayed differently depending on sport and market:
- NBA Spreads / Totals: expressed as a percentage (e.g., +6.2%)
- NHL Moneyline: probability gap in percentage (e.g., +13.3%)
- NHL Totals: goal gap (e.g., +0.83 goals)
- Soccer / Tennis: percentage advantage over market odds
The higher the edge, the more the model is convinced of the bet's value. But note: a high edge does not guarantee a win on any individual game. It is over a sample of 50+ bets that the advantage materializes. That is why solid bankroll management is non-negotiable.
The Day Pass: PRO Access On Demand
Do you not bet every day? The Day Pass is designed for you. For $2.99, you unlock all PRO features for 24 hours:

It is the ideal option for occasional bettors who want access to full analysis only for the big nights: NBA playoffs, Champions League finals, Grand Slam tennis, NHL playoff series.
| Plan | Price | Duration | Best For |
|---|---|---|---|
| Free trial | $0 | 3 days | Discovering the platform |
| Day Pass | $2.99 | 24 hours | Special events |
| PRO monthly | $19.99/month | 30 days | Regular bettors |

Our Results: Full Transparency

At ProbWin, all our results are public and verifiable. Every official pick is time-stamped before the game starts, and its result is recorded automatically. No retroactive edits, no picks quietly removed.
Here are our all-time performance figures by sport:
| Sport | Win Rate | Number of Picks | Period |
|---|---|---|---|
| MLB | 64.1% | 2,314 picks | All-time |
| NBA | 61.2% | 477 picks | All-time |
| NHL | 59.6% | 2,540 picks | All-time |
These figures are calculated exclusively on official picks — AI trends are not included. Every pick is tracked with its opening odds, closing odds (CLV), and final result.
Why These Win Rates Matter
In sports betting, the break-even point sits around 52.4% for standard-margin markets (-110 / 1.91). A win rate above 55% is considered excellent. Our models maintain 59 to 64% across samples of hundreds to thousands of picks — well beyond what luck can explain.
Review our detailed results on the results page where every pick is listed with its status, odds, and edge.
The Importance of CLV (Closing Line Value)
We also track CLV — the gap between the odds at the time of our pick and the closing odds. Consistently beating the closing line is the #1 marker of a profitable bettor over the long run. Sharp money moves lines: when our picks move in the right direction, it validates that our models are identifying the same inefficiencies the market eventually corrects.
How Our AI Works
ProbWin's prediction engine is built on machine learning models trained on years of historical data. The approach varies by sport:
Soccer: Expected Goals (xG) and OSXG
For soccer, the core signal is expected goals (xG) — a metric that measures the quality of scoring chances rather than just the final score. Our V5 models layer in OSXG (shots quality adjusted) and use 5 to 10 recent matches as the primary feature window.
The AI focuses on Over/Under 2.5 and BTTS markets because goals are more structurally predictable than match outcomes. For a deep dive, read our xG guide.
NBA: Pace and Game Script
For basketball, the model uses the Game Script method: project the game's flow quarter by quarter before deciding. Key inputs include offensive and defensive ratings, pace (possessions per 48 minutes), injury-adjusted lineups, and blowout dynamics when the spread is large.
The model avoids the "combined average vs line" trap — a circular reasoning pattern that adds no predictive value.
NHL: GSAx and Confirmed Goalies
Hockey predictions hinge on the confirmed starting goalie. A team's expected goals against shifts dramatically based on who is in net. Our NHL models use Goals Saved Above Expected (GSAx), Corsi for shot volume, and fenwick metrics.
If the starting goalie is not confirmed before the model runs, the game is skipped entirely. This discipline has been critical to maintaining an edge in the NHL market.
Tennis: Surface-Adjusted Elo
Tennis predictions use an Elo rating system adjusted for surface (hard court, clay, grass) combined with serve/return statistics and recent form. Odds are benchmarked against Pinnacle — the sharpest market available.
Bankroll Management: The Foundation
Having access to AI picks is only half the equation. The other half is how you size your bets. Even the best model in the world will ruin your bankroll if you bet recklessly.
The core rules:
- Never bet more than 1-3% of your total bankroll on a single pick
- Flat betting (same stake on every pick) is the most consistent approach for tracking results honestly
- Do not chase losses — if you lose three picks in a row, that is normal variance, not a signal to increase stakes
- Track everything — date, odds, stake, result, edge — so you can evaluate performance over time
For the complete framework, read our bankroll management guide.
The combination of positive expected value (what ProbWin provides) and proper stake sizing (what you control) is the only sustainable path to profitability in sports betting.
Frequently Asked Questions
Is ProbWin free? — Registration is free and includes a 3-day PRO trial. After the trial, your free account gives access to AI trends and historical results. Detailed official picks require a PRO subscription or Day Pass.
Does the AI win every time? — No. No model predicts the outcome of an individual game with certainty. The AI's strength lies in its statistical edge over a large number of bets. With a win rate of 59-64%, you will lose individual bets — but over 100+ picks, the math works in your favor.
Should I follow every pick? — Ideally yes, to maximize the statistical edge. Cherry-picking only the picks that "feel right" to you reintroduces emotional bias — exactly what AI is designed to eliminate. If your bankroll is limited, focus on picks with the highest edge.
How many picks per day? — On average, ProbWin publishes between 2 and 8 official picks per day across all sports. Some days (playoffs, European weekend), there can be more.
How should I manage my bankroll? — Never bet more than 1-3% of your total bankroll on a single pick. For a complete framework, read our bankroll management guide.
What is the difference between an official pick and an AI trend? — An official pick has exceeded the confidence threshold, passed edge validation, and cleared all quality control filters. It is tracked in our public results. An AI trend is the model's directional view when confidence does not reach the publication bar — useful context, but not a betting recommendation.
Can I use ProbWin picks on any bookmaker? — Yes. Our picks include the predicted side and market. You choose where to bet and at what odds. For best results, use bookmakers with the lowest margins (Pinnacle, Betfair Exchange, or similar sharp-friendly books).
