Pick match outcomes to build your parlay

A parlay builder is a free tool that lets you combine multiple betting picks into a single bet slip — known as a parlay, accumulator, or multi-bet. Instead of placing individual bets on each match, you select outcomes across different games and sports, and the odds multiply together for a much higher potential payout.
Our parlay builder goes further than most: it uses AI-powered predictions and expert analyst picks to help you make smarter selections. Whether you want to pick from standard markets (1X2, moneyline) or use Predicto's AI and expert picks, you can build, calculate, and share your parlay — completely free.
Building a parlay with our tool takes just a few steps:
Our built-in parlay calculator automatically computes your combined odds and potential payout in real time. The math is straightforward: multiply the decimal odds of each pick together.
For example, if you pick three outcomes at odds of 1.85, 2.10, and 1.75, your combined parlay odds are: 1.85 × 2.10 × 1.75 = 6.80x. With a $10 stake, your potential win is $68.00.
When bookmaker odds aren't available for a match, our Predicto Estimated Odds engine calculates approximate odds using a Poisson statistical model based on team performance data — goals scored, goals conceded, win rates, and historical stats. These estimated odds are marked with an "EST" badge so you always know the source.
What makes our parlay builder unique is the Predicto Picks mode. Instead of just picking from standard markets, you can select from picks provided by:
Both AI and expert picks come with odds attached, so you can build a complete parlay using only Predicto's predictions. All picks are updated daily to reflect the latest data and upcoming fixtures.
Our parlay builder supports four major sports with coverage across the world's top competitions:
You can mix picks across all four sports in a single parlay — something most parlay builders don't offer.
The more picks you add to your parlay, the higher the potential payout — but also the higher the risk. Here's a quick reference for how parlay odds scale with average odds of 1.90 per pick:
| Picks | Combined Odds | $10 Payout |
|---|---|---|
| 2 picks | 3.61x | $36.10 |
| 3 picks | 6.86x | $68.59 |
| 4 picks | 13.03x | $130.32 |
| 5 picks | 24.76x | $247.61 |
| 6 picks | 47.05x | $470.46 |
Use the stake presets ($10, $25, $50, $100) in the Parlay Slip or enter a custom amount to instantly see your projected winnings. Once you're happy with your picks, download the slip as a shareable image with our watermark branding — perfect for sharing your parlay card on social media.
