The Cold Line58 books and markets plus the sharpest lines on the planet, all in one spot.
The number before the number
Build your own fair value line before you compare it with the game line.
The Cold Line gives you the research, context, simulations, and tracking tools to form an independent view of the game, and to review how your process held up.

NFL Survivor planners
Plan a survivor entry week by week: a standard 18-week pool or the Circa-format 20-leg season with its Thanksgiving and Christmas legs. Used teams, byes, and opponents stay visible as you go.
Free, no account needed to try. A free account saves your plans. Unofficial.
Test your what-if scenarios
Simulation Lab and the From-scratch engine
Change a starter, the conditions, or your own numbers and rerun the game. The From-scratch engine adds a stats-only baseline that never sees the betting line, so you can see how far your assumptions move things.
A sandbox for your assumptions, not a pick service.
Before first pitch
Wind carry range
See which way the wind is blowing at every park, relative to center field, and whether the roof is open. The Wind carry range card adds the feet that wind and air add to or take from a fly ball, with Groundskeeper or any paid plan.
Carry rangeLocked: included with Groundskeeper
The carry range is a conditions estimate, not a home run forecast.
Once the game is live
NextDown drive odds
Follow a live NFL drive with the chance of each ending: touchdown, field goal, punt, or turnover, updated from down, distance, field position, and clock.
Model estimates for following the game, not guarantees.

Why the order matters
Build first, then compare
Start with the sportsbook's line and it can anchor your opinion before you have one. Build your number first, from the information you trust, then compare it with the game line.
An independent number is not automatically more accurate. The value is the process: deliberate, written down, and easy to review after the game.
- Your number
- The fair line you build from your own assumptions, research, and analysis.
- Game line
- The line a sportsbook is offering for the same game.
- Sharp reference
- A separate market price that Edge Scanner compares a sportsbook against.
- Difference
- The measurable gap between two numbers. Something to look into, not a guarantee.

Choose a game
Start with the game you want to study: NFL, Team A at Team B.
- Step 2The Cold Line
Review the information
The Builder lays out the inputs: wind blowing across the field, Team A on short rest, and Team B's left tackle listed as questionable.

Start from the data-driven dials, change what you believe, and the Builder turns it into your fair spread.

With your number set, now look at the sportsbook line for the same game. Building first keeps that line from anchoring your number.

Explain the difference
The book rates Team A 1.7 points stronger than you do. That is a disagreement to look into, not a guarantee, and your number is not automatically the more accurate one.

Then compare
Compare it with the market
Only after your number is set do you look at the game lines. A difference is something to look into, not a guarantee, and your number is not automatically the more accurate one.
Edge Scanner is a separate check: it compares a sportsbook's moneyline, spread, and total with a sharp reference price across the slate.

Method and trust
What The Cold Line is, and is not
- Analysis only, for adults 21 and older. The Cold Line does not accept or place wagers and is not a sportsbook.
- We do not sell picks or pay prizes, and nothing here promises a result.
- Your number is not automatically more accurate than the game line. The method is a habit: build it, compare it, write down why, and review it later.
- The worked example uses made-up numbers and says so. Access labels on this page come from the plan configuration.
FAQ
Questions before you join
What does "The number before the number" mean?
Build your own fair value line before you compare it with the game line. Seeing the sportsbook's number first can anchor your opinion, so you set your number first, then look at the game line and study the difference.
Does The Cold Line sell picks?
No. The Cold Line is research software. You build your own number and decide what, if anything, to do with it. We do not sell picks or pay prizes.
Does The Cold Line take bets?
No. The Cold Line does not accept or place wagers and is not a sportsbook. It is analysis only, for adults 21 and older.
Do I need betting experience?
No. Learn has plain-English lessons on how lines, odds, and prices work, with videos and quizzes. The betting terms glossary has definitions and worked examples for common betting terms. Both are free, no account needed.
What can I use without an account?
These open without an account: Weather Command, Sports calendar, Standard NFL Survivor planner, Circa Survivor planner, Learn, Betting terms glossary, Bet calculators, and Odds tools. Free weather shows field view, conditions, temperature, hourly rain, and one wind-direction arrow. Any paid plan adds wind speed, ball carry, field-goal lines, swirl, and air quality.
What does a free account add?
A free Rookie account adds Cold Line Builder (builder preview and 5 saved builds per UTC day), Odds Board (delayed odds), and Alerts (email alerts). The Standard NFL Survivor planner and Circa Survivor planner save separate plans to your account. Signing up needs no card; you confirm your email to start.
What do Pro and Sharp cost, and what do they add?
Pro is $29.99/mo and Sharp is $99.99/mo at the launch rate, which stays the same while your paid membership is continuous. Pro includes: Full Cold Line Builder (all dials + unlimited saved builds); Forward Test Lab: paper-test your Builder reads without placing a bet; Bet Tracker: log supported bets and see them graded automatically. Sharp includes: Audits: tracked sportsbook moves beside play-by-play on one Eastern Time timeline; Edge Scanner: compare your sportsbook with a sharp reference across moneylines, spreads, and totals; Live game context: Plate Read for MLB and supported NextDown sport desks. Groundskeeper is the full alert pipeline from The Cold Line (TCL), plus the weather desk, at $9.95/mo: every alert except Edge Scanner alerts, by email, in-app inbox, and browser push. It includes breaking injuries, game-time decisions, and in-game exits; breaking news, trades, lineups, starting-pitcher changes, and wobble alerts; rain delays, restarts, postponements, and doubleheaders; roof open/close and high-wind alerts; 3 custom alerts of your own, the same as Pro; live game alerts: scores, period ends, home runs, and goal scorers; the weather desk: wind, carry projections, roof and dome state for every park. Telegram is not part of the plan; it is a separate add-on. Pricing lists everything in each plan, with monthly and annual prices.
What is the difference between your number, the game line, and the sharp reference?
Your number is the fair value line you build from your own assumptions. The game line is what a sportsbook is offering. The sharp reference is a separate market price that Edge Scanner compares a sportsbook against; it comes from the market, not from anything you enter. The difference is the measurable gap between two numbers, not a guarantee of value.
Which sports and markets are covered?
The tools cover NFL, NCAAF, NBA, NCAAB, WNBA, MLB, NHL, and Soccer, and coverage differs by tool. Cold Line Builder, Odds Board, and Edge Scanner work with the moneyline, spread, and total.
How current is the data?
It depends on the tool and your plan. On Odds Board, a free account sees delayed odds. Pro or Sharp adds 30-second delayed odds and 24-hour line movement. Sharp adds real-time odds, full line movement, and consensus. Live tools follow the game while it is on.
Is a card required for the trial?
Yes. A payment method is required to start the 7-day Sharp trial. Cancel before it ends to avoid a charge; otherwise the selected monthly or annual price is charged automatically and the subscription renews at that cadence until cancelled. Pro, add-ons, and Groundskeeper have no trial and are charged at checkout. A free Rookie account needs no card.
How do cancellation and refunds work?
Cancel any time from your account page. Cancelling stops future renewals and you keep access until the end of the period you already paid for. We email you before an annual plan renews. You get a full refund of your first paid charge if you email us within 14 days of that charge. Renewals are not covered; see the Refund Policy.
How do alerts reach me?
Every alert lands in your in-app inbox. Delivery outside the inbox depends on your plan. Rookie: email. Pro: email and browser push, plus Telegram as a $4.95/mo add-on. Sharp: email, browser push, and Telegram. Groundskeeper: email and browser push. Outside channels start off; you turn on the ones you want in your account. During quiet hours, browser push and Telegram stay silent while email and your inbox still get the alert.
What happens to a guest Circa Survivor planner draft when I sign up?
It does not transfer. You can use the planner without an account, but without an account you play one build at a time, and nothing is saved. A guest draft lives only in that browser tab, so create your free account before you build a plan you want to keep. Saved builds stay on your account. A free Rookie account can keep more than one.
How do I get help?
