Parlay betting is one of the most popular bet types, combining multiple bets into one single wager. It is appealing to bettors as it offers the allure of a big payout, but that also comes with a higher risk. Instead of creating parlays based on pure instinct or a ‘feeling’, many bettors now use parlay builders and optimizers.
These are specialized tools that use algorithms, data, analysis, and probability to help users create smarter, more informed parlays. Below are some of the best tools available today, along with our ratings and the groups for whom these tools are most suited.
What are Parlay Builders & Optimizers?
Parlay builders and optimizers are sports betting tools that help you build and optimize parlay bets. The best betting tools utilize historical data and analysis to identify the best prices on the market and appealing combinations that would maximize potential payouts.
These tools are a huge time-saver, as they simplify a process that would otherwise require bettors to manually search for the best odds and events to add to their parlays. They have been designed for bettors who want to take their betting activity to the next level and create parlays with a statistical edge.
Optimizers help to calculate a bet’s expected value (+EV) for users by analyzing likelihoods of events and then comparing sportsbook odds to true probabilities. This gives bettors a true edge and helps them identify profitable opportunities.
Top Parlay Builders & Optimizers
There are lots of tools that offer these tools. Below are some of the best parlay builders and optimizers available in 2026.
#1. OddsJam
OddsJam provides one of the most comprehensive parlay builders on the market. The site is renowned for providing detailed analysis to help customers make more informed decisions and is one of the most sophisticated tools available. OddsJam brings +EV analytics and real-time odds to the table as users construct their parlays.
Key Features:
- Creates parlays that target positive EV rather than just following public trends
- Very customizable regarding the number of legs, sports, and odds ranges
- Extremely fast odds processing
While we feel the OddsJam parlay builder and optimizer is the best on the market, due to speed and the detailed analysis, we must caveat that by saying it is expensive. A Gold subscription comes in at $200 per month, which is considerably higher than other betting tools.
OddsJam is ideal for serious bettors, and if you are willing to pay the subscription cost, you can take advantage of arbitrage/middle scanning, +EV detection, and optimization all in one dashboard.
#2. Juice Reel
Juice Reel’s AI parlay generator utilizes real-time betting market statistics and data to create multi-leg parlays that have been designed to provide value for users. One of the main reasons we like this parlay builder is that it simulates price in juice and game outcomes. The generator also alerts users to any inefficiencies. The main principle behind this feature is that the picks aren’t based on gut instinct, but rather created by models that think like sharps.
Key Features:
- AI simulates game outcomes
- Users alerted to inefficiencies across the board
- Finds legs that offer a statistical edge
If you are willing to embrace AI technology, then the Juice Reel AI parlay generator is ideal. It is quite a cold experience; we feel like it is fun to go with our knowledge sometimes, especially for parlays. However, this is certainly an effective tool, and you can’t argue with the fact that it is completely free to sign up.
#3. HOF Bets
The HOF parlay optimizer gives users the chance to assess each leg of their parlay and compare the odds to what different sportsbooks are offering. Like OddsJam, it simplifies the whole process of creating a parlay, breaking down each leg so you can easily identify your strongest and weakest legs. There is a lot of historical data available so you can check past player or team performance and then determine if this will decrease or increase the odds of your bet.
Key Features:
- Easy-to-use mobile interface
- Parlay breakdowns that show +EV and hit rates
- Optimizer provides different ways you can analyze results: Game logs, correlation, and charts
A big reason HOF Bets makes this list is the affordable pricing. Compared to other tools, paying a subscription price of $19.99 per month is an excellent value for what you get. We would say more advanced bettors may find there are limitations in terms of the data and stats provided, but this is a great option for beginners.
#4. Monster.Bet
We have read multiple user reviews of the Monster.Bet platform and have found users consistently praise the parlay betting features. Players have the ability to generate AI-optimized bet slips or use the analytics and data to create one from scratch. It is the AI feature we particularly like, as it is very unique, but not complicated to use. All you need to do is enter your sport, number of legs, markets, which games, choose a sportsbook(s), and then choose the risk level of your parlay. Once you have done this, Monster.Bet will scour the betting markets, looking at the odds from your chosen books based on your criteria.
Key Features:
- Data is updated really fast in real-time throughout the day
- AI-optimized bet slips are easy to use
- Evidence of providing consistent parlay winners
Monster.Bet provides you with high-value, appealing propositions that meet your risk threshold. Users often point how how the Monster.Bet parlay generator creates winning bets that bettors typically wouldn’t create themselves. That is key for us, as it is clearly adding value to your betting experience. The pricing is in the mid-tier range at $50 per month.
#5. Bettor Odds
Bettor Odds monitors over 30 sportsbooks and hundreds of betting markets to identify the most profitable betting opportunities. The Bettor Odds parlay builder provides functionality to help users place parlay wagers that are +EV. Used in conjunction with the line shopping feature available on the platform, players can create a standard parlay or an SGP all while using the best odds in the market. Bettors also have the ability to use direct linking on the site, allowing them to place a parlay bet into a bet slip with one click.
Key Features:
- One-click functionality
- Accurate projections
- Helps you create parlays with a true mathematical edge
Simplicity is one of the biggest factors we look at when assessing parlay builders and optimizers, and the Bettor Odds parlay builder certainly ticks that box. When you have added all of your legs, the site will do all of the legwork for you and will tell you which is the best sportsbook to place your bet. You will also be given the average market price, the expected price, and the EV calculation, so you can make a more informed parlay bet. It may not look as sophisticated as OddsJam or be as cheap to use as Juice Reel, but it is still one of the better parlay builders out there in our view.
How Do Parlay Builders & Optimizers Work?
For the purpose of explaining how parlay builders and optimizers work, let’s split them into categories and first explain the principles behind parlay builders.
Parlay builders have been designed to allow users to easily combine several selections (legs) into one single parlay wager. The main benefit of using parlay builders is that they simplify the whole process and save time. You browse all of the markets across different games or within the same (an SGP), and as you click on each predicted outcome, the parlay builder automatically adds it as a selection on your bet slip.
The builder also multiplies the odds of each leg in real-time, so you can view the entire odds for the whole parlay and also see the potential payout once all legs have been added.
Parlay optimizers are more advanced than parlay builders. They are analytical tools that use real-time data and statistical models to identify the most profitable combinations. The best optimizers can pick out correlated events that are more likely to occur than a standard parlay calculator would suggest. This means you are gaining a true edge.
Optimizers scan millions of odds quickly and are constantly refreshing to identify the best +EV parlays. Like builders, optimizers and a huge time saver as you don’t need to manually research each bet, as the suggestions and given to you.
Summary
Choosing the best parlay builder and optimizer depends on several factors, including budget, experience level, and your desire to analyze parlays. For example, if you are a beginner looking for a budget-friendly option, then HOF Bets would be a great choice. Alternatively, if you are a serious bettor looking for the highest edge and willing to invest, then OddsJam would be more suitable.
