Alternate Lines (Alt Lines)
Alternate lines are secondary spreads or totals offered alongside the main line. If the main NBA total is 224.5, alt totals might include 218.5, 220.5, 228.5, 230.5 — each at different odds reflecting the new probability.
How Alt Lines Work
Books peg one "main" line (closest to 50/50) and quote secondary lines at adjusted prices. Cross a key number — e.g., shift NFL total from 44.5 to 47.5 — and the price moves to reflect the lower probability. The bookmaker margin (vig) often stays roughly constant per pair, but inefficiencies creep in further from the main line.
Why Alt Lines Often Have More Value
Sharp money concentrates on the main line. Alt lines are priced by traders and models with less data behind them, so they get re-priced slower when underlying inputs change (injury news, weather, sharp moves). This makes alt lines a recurring source of +EV for line shoppers.
Alt Lines vs. Teasers
A teaser moves the line in your favour but reduces the payout in a fixed ratio defined by the bookmaker. An alt line lets you pick any available number at its actual market price — much more flexible, usually better value if you can shop across books.
Finding +EV Alt Lines
1. Pull alt-line prices from multiple books. 2. Compute fair odds by devigging the matching pair (Over X.5 / Under X.5). 3. Bet the side at the best book when offered price beats fair odds. EVBets surfaces alt-line value automatically across totals and spreads markets for tier-1 sports.
Frequently Asked Questions
Are alt lines more profitable than main lines?
On average, no — vig is similar. But individual alt prices misalign more often, so a disciplined line shopper can extract more +EV per opportunity than from main lines alone.
Which sports have the most alt-line value?
NFL spreads/totals, NBA totals, NHL totals, and MLB run totals. Soccer alt-totals (Over 1.5 / Over 3.5 etc.) frequently mispriced at soft books.
Should I bet alt lines on parlays?
Parlaying multiple alt-line legs is popular but compounds vig. Each alt leg adds 4–6% house edge — three legs at 5% vig = ~14% expected loss. Stick to single +EV alt bets.
