Sportsbooks compete for customers with promotions: deposit matches, bonus bets, risk-free first bets (often structured as bonus credit), odds boosts, parlay insurance, and seasonal campaigns.
Promos can be genuinely valuable—but only when you understand what you are receiving, what strings are attached, and how that changes your expected value.
This article is a framework, not a list of current offers (those change weekly).
Types of Promotions (Conceptual)
Bonus bets / site credit
“Bonus bet” can mean different things depending on the book:
- Sometimes you receive a token that pays profit but not stake
- Sometimes you receive site credit that must be played through
- Expiration dates and minimum odds restrictions are common
Odds boosts
Boosted prices can create +EV opportunities—if the boosted line is better than your fair price and the maximum bet size still clears your time cost.
Insurance and refunds
Parlay insurance may refund stake as site credit (not cash), which has lower economic value than a true cash refund.
Playthrough, Rollover, and “Free Money” Math
Many bonuses require wagering a multiple of the bonus before withdrawal. A large bonus with extreme rollover can be worse than a small bonus with clean terms.
When evaluating a promo, ask:
- Cash vs bonus credit?
- Expiration timeline?
- Minimum odds and restricted markets?
- Rollover requirement and contribution rules?
Promos + Your Betting Process
Promotions work best when paired with habits you should use anyway:
- Line shopping (get the best price)
- Bankroll discipline (do not chase losses with bigger promos)
- Honest tracking (did the promo improve EV after accounting for time and restrictions?)
If you are building a process around +EV betting, revisiting core expected value concepts pairs naturally with promo evaluation—promos are just another input into the same EV calculation.

Promotions are designed to increase engagement. If you find yourself depositing more than you planned because an offer “expires,” pause and revisit limits.
Frequently Asked Questions
Are promos always +EV?
No. Some are marketing-priced; others have constraints that wipe out value unless you bet frequently anyway.
Should I create accounts at many books?
Multiple accounts can help you shop lines—where legal—but only open accounts you intend to use responsibly.
What is the difference between a risk-free bet and a bonus bet?
Naming varies. Read the terms: many “risk-free” offers refund losses as non-withdrawable site credit.
Can I use PropFinder with promos?
You can compare lines and evaluate whether a boosted or alt line still looks mispriced relative to your research—tools support decision-making; they do not replace reading promo rules.
