Props, spreads, totals, and moneylines
Find the player props, spreads, totals, and moneylines your sportsbook is pricing wrong.
Pick the sportsbook you bet at. The Optimizer checks every game line and player prop there against what the rest of the market charges, then puts the best-priced bets at the top. You see what other books charge for the same bet, check the live price, and decide for yourself.

Best fit
Who this tool is for
Markets and platforms
Coverage depends on supported books, markets, and user location
Spreads, totals, moneylines, and player props at supported sportsbooks, exchanges, and prediction markets where Upside has current odds coverage.
Availability varies by sport, league, book, state, jurisdiction, user account, event timing, and whether a market is open at the source sportsbook.
DFS pick'em slips on apps like PrizePicks and Underdog have their own workflow in Fantasy Props and on the PrizePicks Optimizer page.
Upside scans 30+ sportsbooks, DFS apps, exchanges, and prediction markets across the product, but each tool has its own coverage rules and data availability.
Workflow
What to check before making your own decision
Pick the book you actually bet at
The Optimizer ranks one book at a time. Choose a book you have funded, then narrow league, game day, and markets to what you want to cover. A 2% edge at your main book is worth more than a 4% edge at a book you cannot use.
Build an edge list before opening a book
Sort by EV and review the top rows first. Game-line edges tend to be smaller and props tend to carry lower limits, so check both the edge and the limit before a row makes your list.
Use calculators to verify price and stake
Pair optimizer rows with the EV, No-Vig, Implied Odds, or Kelly calculators when you want to understand probability, fair price, and sizing before making your own decision.
Confirm live availability and track results
Open the sportsbook to verify the market is live, then track closing-line value and process quality. Upside provides analytics, not betting advice, wager placement, or guaranteed outcomes.
Before relying on the data
- Does the live sportsbook still show the same event, market, side, line, and price as the row you reviewed?
- Is the sportsbook usable in your jurisdiction and account, and are limits or rules likely to affect the decision?
- Are stake sizing, bankroll limits, variance tolerance, and responsible gambling boundaries defined before you consider acting?
Questions
Common Sports Betting Optimizer questions
What is the Sports Betting Optimizer?
It is Upside's +EV research board for sportsbooks. It ranks player props, spreads, totals, and moneylines at the book you choose by expected value and fair-price gap.
What happened to Game Lines and Sportsbook Props?
They are now one page. The Optimizer shows game lines and sportsbook player props on the same board, and links to the old Game Lines page open this one.
How is it different from Odds Screen?
Odds Screen is a broad line-shopping screen that shows every book's price side by side. The Optimizer is narrower: it ranks the rows at your book by EV and fair-price context.
How is it different from Fantasy Props?
Fantasy Props is built around DFS pick'em slips and their payout rules. The Optimizer is for straight bets at sportsbooks, exchanges, and prediction markets.
Is Upside a sportsbook or betting operator?
No. Upside is informational analytics software. It does not accept wagers, operate a sportsbook, place bets, facilitate wagers between users, or process gambling transactions.
