How sportsbook bonuses work
Welcome offers come in two main shapes. A "bet and get" gives you bonus bets after you place a small qualifying wager (e.g. bet $5, get $200). A first-bet safety net refunds your first bet in bonus bets if it loses (e.g. up to $1,000). Bonus bets are not withdrawable cash - you wager them and keep any winnings. Most current offers need no promo code; the bonus applies automatically when you sign up through an official link and meet the terms.

Frequently asked questions
Which sportsbook has the best sign-up bonus?
Fanatics and Caesars currently have the most generous welcome offers - Fanatics runs a 10x $100 Bet Match paid in FanCash over your first 10 days (up to $1,000), and Caesars refunds your first bet up to $1,000 in bonus bets. FanDuel's bet $5, get $200 is the easiest to clear. The best move is to claim the offers at several books and always bet the best line.
What is the best online sportsbook?
It depends on what you value. We rate FanDuel best all-around for its app and market depth, Caesars best for rewards and its first-bet safety net, Underdog best for player props and pick'em, and Novig best as a no-vig exchange. Smart bettors hold accounts at several and shop for the best number on every bet.
Are sportsbook promo codes safe?
Yes, when you claim them at a regulated, licensed US sportsbook through an official link like ours. There's no risk in entering a welcome offer code - these books are state-licensed and the bonuses are real. Avoid any 'code' offered by an unlicensed offshore site.
How do I claim a sportsbook welcome offer?
Tap a Claim button, create your account, verify your identity, deposit, and place the qualifying first bet described in the offer. Most current offers need no promo code - the bonus is applied automatically when you sign up through the link and meet the terms.
How do sportsbook bonuses work?
Most welcome offers are either a 'bet and get' (bet a small amount, get bonus bets back) or a first-bet safety net (your first bet is refunded in bonus bets if it loses). Bonus bets aren't withdrawable cash - you wager them and keep any winnings.
Are sportsbook bonus bets the same as cash?
No. Bonus bets (or 'bet credits') can't be withdrawn. You place them as a wager, and if the bet wins you keep the profit, but the bonus-bet stake itself is not returned. Treat them as free shots at profit, not as a deposit.
Should I sign up at more than one sportsbook?
Yes. Having multiple accounts lets you line shop - bet the best available price on every game - which is one of the most reliable edges in betting. It also lets you claim multiple welcome bonuses, effectively stacking free value.
What is a betting exchange and why use one?
A betting exchange like Novig lets you bet against other users instead of against the house, so there's no built-in vig (margin). That means you get true, fairer prices - often the best number available. Pair it with our no-vig calculator to see the fair odds on any market.
Are these sportsbooks legal in my state?
Each operator is live only in the states where it's licensed, and offers vary by state. When you tap a Claim button you'll see whether the book is available where you are. Always bet at regulated, licensed US sportsbooks.
Do I have to bet with a sportsbook to use the Wise Guy Team tools?
No. Our betting splits, live odds and eight calculators are free and don't require any sportsbook account. But you'll need a book - ideally a few - to actually place the bets and to get the best line, which is why we recommend the ones above.
