Find the +EV plays the market misses.
The optimizer compares every book's posted price to a de-vigged fair number and flags the plays priced better than fair. It scans 25+ sportsbooks and pick'em apps and deeplinks you straight to the play, and it treats football, basketball, and baseball markets exactly the same way.
Deeplinks into
Every posted price gets measured against fair value
Fair-odds baseline
Each posted price is compared to a de-vigged fair number for the same outcome, so a genuinely generous line stands apart from one that only looks good.
Edge, quantified
When a book prices a play above fair value, the gap is surfaced as a positive expected-value edge, which measures long-run value rather than promising one result.
25+ books, every sport we price
The optimizer scans a wide slate of sportsbooks and pick'em apps at once across football, basketball, and baseball markets, so the +EV plays find you.
Auto-refreshing
Prices move all day as lines shift, so the board updates frequently and the edges you see reflect current numbers rather than this morning's.
One-tap deeplinks
When you find a +EV play, a single tap opens it directly in the sportsbook or pick'em app, so you never have to search for the market yourself.
Works on every device
The optimizer is built to be fast on phone, tablet, and desktop, and you get the same screen wherever you are hunting for value.
Positive expected value, in plain English
Expected value is the average result you would expect from a play if you could repeat it many times. A play is positive-EV when the price you can actually take is better than the fair odds imply, so the payout outruns the estimated true probability. That is the whole game the optimizer plays, market by market and sport by sport.
The reference point is the de-vigged, or "fair," price. Every posted number carries the book's margin, and stripping it out of both sides of a market leaves an estimate of the true implied probability. When a book hangs a number more generous than that fair price, the difference is an edge. Surfacing those gaps across dozens of books at once is the part a person scanning apps by hand cannot match.
One honest caveat belongs here: positive EV is a long-run idea, not a single-play promise. A +EV play can lose and a bad price can win on any given night, because that is variance. The point is that consistently taking prices better than fair tends to add value across many plays. No individual outcome is guaranteed, which is exactly why the tool talks in fair value and edge rather than certainty.
Positive EV, explained
What is a positive EV (+EV) play?
Expected value, or EV, is the average result you would expect from a play if it were repeated many times. A play is positive-EV when the price you can take is better than the fair odds imply, meaning the payout is larger than the estimated true probability warrants. Positive EV measures long-run value, and it never guarantees a single result.
How is a +EV opportunity found?
The optimizer compares the price posted at each book to an estimate of the fair, de-vigged price for the same outcome. When a book hangs a number more generous than that fair price, the difference is a positive expected-value edge. The tool surfaces those gaps across many books and markets at once, so you are not checking each app by hand.
Which sports and markets does it scan?
The finder works on the markets MySpariEdge prices, so football, basketball, and baseball prices run through the same fair-value comparison as each season comes around. Game lines and player props are treated the same way, because a price either beats fair value or it does not.
What does 'de-vig' or 'fair odds' mean?
Sportsbook prices include a built-in margin called the vig. Removing that margin from both sides of a market produces a de-vigged, or fair, price, which estimates the true implied probability without the house edge. Fair odds are the yardstick a +EV finder measures each posted price against.
Why does a +EV play still sometimes lose?
Positive EV describes the value of a price over the long run, not the result of one play. A +EV play can lose and a negative-EV play can win on any given night, because variance is normal. The idea is that consistently taking prices better than fair tends to add value across many plays, so no single outcome is a promise.
Does line shopping matter for +EV?
Yes, and the two go together. The same outcome can be priced differently at every book, so a +EV finder is really a way of shopping every line at once and flagging the ones that beat fair value. Taking the best available number each time is what turns a small edge into a meaningful one over a season.
Which sportsbooks and apps are covered?
The optimizer draws from a wide slate of sportsbooks and pick'em apps, including DraftKings, FanDuel, PrizePicks, Underdog, Novig, Polymarket, Kalshi, and 25+ more. When you find a play, a one-tap deeplink opens it directly in that app, so you are not hunting for the market yourself.
