“Most bettors focus on picking winners. We focus on finding value. A horse that wins at even money is a bad bet. A horse that loses at 10-1 can be a great one. The Race Analyzer shows you the difference — every night, before every race.”
The real problem
You’ve been handicapping for years. You’re still down.
You know the form. You study the trainers. You find horses you like. And at the end of the meet, you’re still down. Here’s the part nobody tells you — picking winners and betting profitably are completely different skills.
You win races and lose money
A 40% winner at 3-5 is bleeding you dry. Profitability isn’t about hit rate — it’s about whether the price offered was worth the risk you took.
You never know when the price is right
Without independent probability estimates, you’re comparing your opinion to the crowd’s. You need a number that has nothing to do with either.
You have no objective baseline
Every other tool tells you who to bet. None of them tell you whether the price justifies the bet. That’s the only question that matters for long-term profit.
What you receive
Two tools. Delivered every night. Ready before the first race.

The framework behind it
The horse racing probability calculator behind every number.
The Algorithm Factors system analyzes over 13 million data points to produce independent probability estimates for every horse. These aren’t opinions. They’re not adjusted for public money. They reflect what the math says the true odds should be.
When the tote board shows a horse at 12-1 and our system says 6-1, that’s an overlay. That’s a bet worth making. When the tote says 3-1 and we say 4-1, you pass. Most races: pass. Some races: act. That’s the discipline that makes this work.
How subscribers use the ratings
The gap between our number and the track’s is your entire edge.
Each night you receive Algorithm Factors’ independent probability estimate for every horse. You open the tote board. You compare the two numbers. When the track’s implied odds are higher than ours, a value edge may exist. When they aren’t — and most of the time they aren’t — you close the Race Analyzer and watch. Waiting is a strategy. Patience is an edge.
One good exacta can pay for your subscription many times over.

How To Make A Living Betting Horses
A Probability-Based Framework for Understanding Horse Racing Markets
10 verified Amazon reviews
Gary Levin spent decades studying probability, betting markets, and the mathematics of parimutuel wagering before building the Algorithm Factors system. His work has been recognized by courts as expert-level analysis in the mathematics of gambling.
The Race Analyzer tells you what the math says. The book explains why the math works — why most bettors lose, why favorites can cost you money, and why the discipline to pass most races is the single most important skill a serious bettor can develop.
“Winning bets do not necessarily mean good decisions, and losing bets do not necessarily mean bad ones. Over time, only decisions with positive expected value matter.”
— Amazon reviewer
What readers say on Amazon
The book changes how you think about betting.
“This book is unlike any other handicapping book I’ve read. There are no chapters dedicated to speed, class, or trainers. It deeply explores the mathematics of betting in a parimutuel system. A sharp change in the way I now approach betting on horses.”
Verified Amazon reviewer
“The author explains that a strategy can win often and still lose money if the odds are poor, while a strategy that wins less frequently can still be profitable when the prices are right. That changed the way I think about betting.”
Verified Amazon reviewer
“This book completely changed the way I look at horse racing. Rather than promoting unrealistic promises, it teaches readers how to think like an investor and assess risk objectively. An invaluable resource.”
Verified Amazon reviewer · Los Angeles
“Levin does a superb job explaining how to identify mispriced horse racing markets and manage bankroll risk systematically. The emphasis isn’t on picking winners, but on finding long-term positive expected value (+EV).”
Verified Amazon reviewer
“The sections on expected value being ‘direction, not destiny’ and why most races should be passed were outstanding. The chapters on calibration, bankroll survival, and risk of ruin were packed with practical insights.”
Verified Amazon reviewer
“Most horse racing books try to teach you how to pick winners. This book focuses on something more important: how to think about betting correctly. A thoughtful guide for bettors who want a disciplined, long-term approach.”
Verified Amazon reviewer
The book explains the framework. The Race Analyzer puts it to work every night.
What subscribers say
The ratings work because the math works.
“I’ve been playing horses for 20 years. The Race Analyzer alone is worth the subscription. I stopped guessing at value the first week I used it.”
Subscriber · Belmont
“The analyzer is easy to use at the track. I load my files before I leave the house, circle the overlays, and I know exactly what I’m doing when I get to the window.”
Subscriber · Churchill Downs
“Hit a $340 exacta in the first two weeks. Paid for six months of the service in one afternoon. I’ve been a subscriber ever since.”
