What Locktopus Odds is
Locktopus Odds is an odds comparison service on the web. It lines up prices from many sportsbooks and exchanges so you can see where one book pays more than the market.
On top of that sits a set of tools. A positive EV (+EV) tool estimates a fair price for each bet and ranks bets that beat it. An arbitrage tool finds opposing bets at two books whose prices differ enough to cover both sides. Our EV calculator and arbitrage calculator show how both ideas work.
Who Locktopus Odds is for
This is for bettors who are comfortable with the price-shopping approach and hold accounts at several US sportsbooks. The more books you can use, the more of the flagged bets you can act on.
It also suits prop bettors who want to see where one book's number differs from the pack, and people who like to log bets and check closing line value.
It is a weaker fit if you have only one account, or if you want picks handed to you. The board shows US sportsbook prices, so bettors using Canadian provincial books will not find those books on it. The terms also set a minimum age to use the service, so check them first.
How it works
The free and paid parts split like this:
- The odds screen is a free tool. It shows every listed sportsbook's price on game lines and player props in one table.
- Free calculators, including a vig remover and an odds converter, work without an account.
- Paid plans add the +EV tool, ranked by edge, plus prop outliers, arbitrage and auto-generated same-game parlays.
- A beta feature prices pick'em lines from sportsbook odds.
- The bet tracker logs your bets and shows closing line value, so you can judge whether you are getting good prices over time.
- A futures page compares championship, division, award and win-total odds side by side.
- An in-app assistant is included. The terms say your messages go to an outside AI provider to generate answers, so avoid sharing sensitive details.
Plan names run from basic odds comparison up to the full +EV toolkit and a faster live-odds tier.
What to weigh before subscribing
Locktopus loads its prices dynamically, and we couldn't confirm them from its site, so check current plans and pricing there before you subscribe. Plans are offered on different billing periods.
Cancellation runs through a billing portal and access continues to the end of the paid period. There are no partial refunds for unused time.
Arbitrage and +EV betting take work. You need to move quickly, place bets accurately, and keep enough funds at each book. Lines can move before you place both sides, which can leave you exposed on one leg.
Sportsbooks may limit or close accounts that bet this way, and arbitrage bettors are often targeted. Plan on that rather than hoping to avoid it. A tool cannot stop a book from restricting you. Our Kelly criterion calculator can help you size stakes while you learn.
A flagged edge is an estimate. It depends on the quality of the market data, so check each bet before you place it.
Bottom line
Locktopus Odds is a broad price-shopping toolkit, with a useful free screen and calculators and a paid layer for +EV, outliers and arbitrage. It fits bettors with several US accounts who accept the learning curve and the risk of limits. If you bet at one book, the free tools are the sensible place to stop.
