Making Advanced or Flat Bets with Miller’s Strategy

August 9, 2023

Regarding sports betting, having a well-defined plan is essential for long-term success. Professional bettors often rely on advanced strategies to gain an edge over casual bettors. One such Strategy is the Miller Strategy, which revolves around flat betting. 

In this article, we will delve into flat betting, explore the details of Miller’s Strategy, and discuss its advantages and drawbacks.

What is Flat Betting?

Flat betting involves a disciplined staking structure where the bettor wagers the same amount on every game or event. Unlike impulsive and random betting, flat betting ensures consistency and organization. For instance, if you have a $500 bankroll and decide to bet 5% on each wager, you would consistently wager $25 on every game. 

This systematic approach enhances the chances of long-term profitability in sports betting.

Understanding Miller’s Strategy

Miller’s Strategy is a betting system coined by John R. Miller, a renowned American bettor and author of the book “Professional Gambler.” This Strategy has two primary components:

Focus on Even Odds: According to Miller’s System, concentrate your betting efforts on events ranging from 1.85 or -118 to 1.91 or -110, or as close to 50/50 odds. This focus on near-even odds increases the likelihood of winning and forms the foundation of the Strategy.

Strict Staking Plan: The second part of Miller’s Strategy involves adopting a strict staking plan. Initially, you bet 1% of your total bankroll on each wager until your overall value increases by 25%. For example, if you start with a $1,000 bankroll, your initial bet size would be $10 per game. When your bankroll reaches $1,250 (a 25% gain), you will increase your bet size to $12.50 per game.

The Winning Formula

To achieve long-term success with Miller’s Strategy and beat odds of -118 to -110, you need at least 53% of your bets to be graded as winners. While this may seem challenging, considering you start with a 50/50 chance, a thorough understanding of the sport you’re betting on, including injuries, news, matchups, and other factors, can increase your success rate.

Advantages of Flat Betting

Long-term Profitability: If you strictly adhere to the prescribed approach of betting lines between -110 and -118 and use 1% of your bankroll for each wager, you can make money in the long run, assuming you win at least 53% of your bets.

Flexibility with Improved Odds: Some sportsbooks offer better odds than the standard -110, such as -105 or -108 for NFL lines. If you stick with the flat betting strategy, you could succeed by winning slightly less than 53% of your bets.

Drawbacks of Flat Betting


Rigidity: The flat betting system limits your betting choices to events with odds between -110 and -118. This restricts you from exploring other betting opportunities, such as heavily favored teams or lucrative underdogs.

Discipline Required: The Strategy demands extreme discipline from bettors, which can take away some of the excitement for recreational bettors who prefer more flexible approaches.

Combined with Miller’s Strategy, flat betting provides a structured and systematic approach to sports betting. While it offers long-term profitability and a higher chance of winning, it comes with the drawback of limited betting choices and strict adherence. 

As with any betting strategy, understanding the sport, keeping abreast of relevant information, and maintaining discipline are key factors to maximize success with the flat betting system.
