Site Guide

Every line from 13 sportsbooks runs through 10,000+ Monte Carlo simulations. The letter grade scores your edge — how much better our fair probability is than the book's price.

Only picks that clear our backtested publication gate show B+ or higher. Tap a card for the full evidence, then hit Tail to track it in My Picks.

Every board line gets Over/Under probabilities built from real player game logs. Demons and Goblins carry their own payout multipliers.

Add legs to the slip and it prices your full entry's EV using the actual PrizePicks and Underdog payout matrices — not estimates.

Team futures are graded daily against cross-book devigged consensus; season-long player props are modeled from recency-weighted history. Same grade scale as the rest of the site, longer horizon.

A live ranking of the published picks most tailed by other LineGrade users right now (min. 2 tails). Same grades, same evidence — just sorted by heat instead of edge.

Search any player or team, choose a market and line, and enter the odds you're offered — the model prices it from real game logs. Save it as a book bet, future, or pick'em leg.

Custom picks count toward your personal P&L only — never the model's public Track Record.

Set your unit size in Account. Every tailed, saved, or custom pick logs stake, live status, and P&L through settlement — win, loss, push, or void (postponed and DNP refunds included).

Export the whole log to CSV anytime.

Every published B+-and-up pick is recorded before tip-off and settled in the open. Filter by sport, market, or grade floor.

CLV shows whether picks beat the closing line — the sharpest test of any model. One model era at a time, never blended: use the era selector to switch between v5 (current) and v4.

Follow other bettors and see their picks, join groups, and climb leaderboards ranked by ROI, units, and record. Your picks are only visible to others if you opt in from Account.
