Bonus (Welcome Bonus)

What is Bonus (Welcome Bonus)?

A promotional offer from a sportsbook or casino that gives you extra funds or free bets.

Last updated:February 22, 2026

Welcome bonuses (also called sign-up bonuses) are promotional offers designed to attract new customers. Common types include deposit matches (e.g., 100% match up to $1,000), free bets, and first-bet insurance offers.

Bonuses come with wagering requirements (playthrough requirements) that specify how much you must bet before you can withdraw bonus funds. A $100 bonus with a 10x rollover means you must wager $1,000 before cashing out.

Not all bonuses are created equal. Compare the total bonus amount, rollover requirements, eligible games/bet types, and time limits. A smaller bonus with lower rollover requirements can be more valuable than a larger bonus with restrictive terms.

In practice

DraftKings offers a $1,000 deposit match to a new user. The fine print: the match is released as site credit in $1 increments for every $25 wagered, requiring $25,000 in playthrough to unlock the full bonus. At a 4.5% hold, that wagering costs roughly $1,125 in expected losses — more than the bonus itself.

Profitable bonus hunting targets no-deposit free bets (e.g., Bet $5, Get $200 in bonus bets) and first-bet-safety-net offers (Bet $1,000, get it back as bonus bets if it loses). A $1,000 safety net bet on a +200 underdog has an EV of roughly (0.33 × $2,000) + (0.67 × $700 bonus value) = $1,129, a $129 edge over the $1,000 risked. Always read the rollover, odds restrictions, and expiration before chasing headline numbers.
