Find the sportsbook paying most on every alternate line
A ladder is every line a player's prop is offered at — the main number plus every milestone above and below it. Locktopus prices each one across 30+ sportsbooks, marks the best price on every rung, and puts the market average beside it so you can see which books are off.
- 30+ sportsbooks per rung
- Main line plus every alt
- Market average on every rung
How Ladders works
One player, one market, every line the books will take
- 1
Pick a league and a market
Choose a league and a player market — receiving yards, receptions, passing yards, points, strikeouts. The board loads the players with the most complete ladders in that market.
- 2
Read the grid
Each column is a milestone and each row is a sportsbook. The top row is the best price on every rung and the bottom row is the market average, so the gap between them is the whole story.
- 3
Take the rung you want
Every price is a link straight to that bet at that book. Pin a player to keep their ladder on the page while you compare, and search any player in the market to pull their ladder up.
Built to make the whole ladder legible
A ladder can run twenty rungs deep, most of them thin. Ladders shows the ones worth reading
Best price and market average on every rung
The grid carries a best-price row and a market-average row, so you can see at a glance which milestone a book is furthest off the market on, not just which price is highest.
Rank by the books you actually have
Select your sportsbooks and the board ranks ladders by how many rungs one of your books leads. Without a selection it ranks by how far the best price beats the market.
Thin rungs filtered out
A line only becomes a rung once enough books price it, so the stray half-point numbers a single exchange posts between the real milestones stay off the grid.
Bad quotes caught, not hidden
A price the market-quality checks flag — an inverted line, a quote far off the market, an exchange with no size behind it — stays visible but struck through, and never counts as the best price.
Pre-game and live
Switch the whole board between pre-game and in-play prices. Live ladders move fast, and the board refreshes itself as the books repost.
Rules you set once
Choose how many milestones a ladder needs, how many books a rung needs, how many rungs your book has to lead, and which kickoff window to look at. The board applies them everywhere.
Looking for one mispriced prop rather than a whole ladder?
Ladders shows you every line a player is offered at, side by side. Prop Outliers does the opposite: it scans every player and every market and surfaces only the single props where one sportsbook is paying at least 10% more than the rest.
Who Ladders is for
Bettors who ladder their props
If you take 40+, 60+ and 80+ receiving yards on the same player rather than one number, you need every rung priced at once. That is the whole page.
Anyone building a correlated slip
Alternate lines are where same-game parlay value hides. Seeing the full ladder tells you which milestone to climb to before the price stops paying for the extra risk.
Line shoppers with several accounts
Books disagree far more on alternates than on the main number. The more accounts you hold, the more rungs you will find one of them leading.
Frequently asked questions
What is a betting ladder?
A ladder is the full set of lines a sportsbook will take on one player prop — the main number plus every alternate above and below it. A receiving yards ladder might run from 20+ yards all the way to 150+, each rung at its own price.
What is an alternate line?
An alternate line is any line on a market other than the main one the book posts by default. Alternates pay more as they get harder, and books disagree on them far more than they do on the main number.
How is Ladders different from Prop Outliers?
Ladders takes one player and one market and shows every line they are offered at, priced across every book. Prop Outliers scans every player and returns only the individual props where one sportsbook is at least 10% off the market average.
How is Ladders different from the Odds Screen?
The Odds Screen compares one line across every game in a league. Ladders compares every line for one player, so the columns are milestones rather than games.
How does Locktopus decide which ladders to show first?
With no sportsbooks selected, ladders are ranked by how far the best price on each rung beats the market average, averaged across the ladder. Once you select your books, they are ranked by how many rungs one of your books leads.
Why are some lines missing from a ladder?
A line only appears once enough sportsbooks price it — three by default, which you can change. That keeps the one-off numbers a single exchange posts between the real milestones from cluttering the grid.
Which sportsbooks are included?
Over 30 sportsbooks and exchanges, including FanDuel, DraftKings, BetMGM, Caesars, bet365, ESPN Bet, Fanatics, Novig and ProphetX. Any book that prices a rung appears as a row on that ladder.
Which plan includes Ladders?
Ladders is part of the Pro plan and up. Signed-out visitors and Basic subscribers see a locked page rather than a preview.
