How LineLock helps
Sportsbook odds typically include a built-in margin, often called the vig, that works in the sportsbook’s favor over time. LineLock helps you look for opportunities to shift the advantage toward you. Compare lines across sportsbooks, explore data-driven insights, and use our analysis, tools, and calculators to evaluate value and understand the tradeoffs before you bet. No tool can guarantee a winning outcome—but better information can help you make more informed decisions.
You don’t have to be a sharp or a professional bettor to make informed decisions. And the cost of finding an edge should make sense for your unit size—the amount you typically stake on a bet. That’s why we’ve designed four tiers to fit different needs and budgets, so you can choose the tools that make sense for you.
Your records stay yours. Personal accounts can search and download their bet records on every membership.
LineLock provides information and planning tools; it does not accept or place bets. Confirm current odds, availability and settlement terms with your sportsbook.
