Every offer here is bonus credit you get for signing up — no first-bet insurance, no real-money capital section. Pair the free credit against itself on opposite sides of the same game and withdraw what's left.
"Verified Pairs Profit" covers the 3 fully-matched pairs below only. The Experimental Player Picks section (PrizePicks, Underdog, both Sleeper offers, hedged with Courtside) is shown separately as a range, not a fixed number — that hedge tool is far smaller than the exposure it's covering, so it can't be turned into a guaranteed outcome. Read that section before assuming any of that $220 in multi-leg bonus credit is "safe."
Sign up, claim each book's bonus credit, then bet that credit on opposite sides of the same close-to-even game across two books. One side wins; that's your profit. The losing side only cost free credit, not your own cash.
Sign up and deposit the minimum required on each book below. Most credit you here, free, after the deposit clears.
DraftKings, Bet365, PrizePicks, and Underdog all require a small real-money wager before the bonus unlocks. That's genuine real money on the table, even if small.
Look for the same market at roughly even odds (e.g. -110/-110) listed on both books you're pairing.
One side wins. Remember a winning bonus bet only pays its profit, not the full stake back — that's already factored into the estimates below.
Every book, what it costs, and whether it requires a real-money bet before the bonus unlocks.
| Book | Deposit | Bonus | Real Wager First? | Pairs With |
|---|---|---|---|---|
| DraftKings | $5 | $200 | Yes — $5 real | Bet365 (Pair 1). $50 left over, unmatched. |
| Bet365 | $10 | $150 | Yes — $10 real | DraftKings (Pair 1) |
| Dogghouse | $100 | $100 | No | Rebet (Pair 2) |
| Rebet | $100 | $100 | No | Dogghouse (Pair 2) |
| Fliff | $100 | Up to $100 (100% match) | No | Chalkboard (Pair 3) — usable on straight moneylines |
| Chalkboard | $100 | Up to $100 (100% match) | No | Fliff (Pair 3) |
| PrizePicks | $5 | $50 | Yes — $5 real | Experimental — 2-pick minimum, all-or-nothing |
| Underdog | $5 | $50 | Yes — $5 real | Experimental — 2-pick minimum, all-or-nothing |
| Sleeper | $100 | $100 match + $20 free | No | Experimental — both offers require 2+ picks, different teams |
| Courtside | $10 | $50 | No | Experimental only — single-leg hedge tool |
Confirm current terms directly with each book before depositing — promo structures, minimum odds, and amounts change often and vary by state. Sleeper no longer has a clean spot in the Pairs section: both its $100 deposit match and its $20 free pick now require a 2+ pick entry with players from different teams, which is the same all-or-nothing structure as PrizePicks and Underdog — see Experimental. Fliff takes Sleeper's old spot alongside Chalkboard because its bonus credit can be used on straight moneylines, which is what a clean 50/50 wash needs. Polymarket was removed in an earlier revision and still has no confirmed partner.
These 3 pairs bet the same market on opposite sides across two books, so one side always wins. Profit is fixed regardless of the outcome.
Steps
This section behaves differently from every pair above — read this before you deposit anything.
Recommended: concentrate the $50 on Sleeper's $100 match
Sleeper's $100 match is the largest single exposure and (using Sleeper's typical ~2x minimum multiplier for a 2-pick Max entry — verify the actual multiplier shown before you submit, since Sleeper's odds are pick-dependent, unlike PrizePicks' fixed table) has the best hedge-to-size ratio. PrizePicks, Underdog, and Sleeper's $20 free pick get played straight with no hedge — worst case you forfeit bonus credit, best case they hit on their own.
| Outcome | Sleeper pays | Courtside hedge pays | Total |
|---|---|---|---|
| Both legs hit | $100 | $0 | $100 |
| Leg 1 only hits | $0 | ~$22.73 | ~$22.73 |
| Leg 2 only hits | $0 | ~$22.73 | ~$22.73 |
| Both legs miss | $0 | ~$45.45 | ~$45.45 |

A few things that affect the real outcome, not just the headline number.
Standard spread and moneyline bets with equal juice on both sides are easiest to match across books. Heavy favorites make matching amounts harder and change the math above.
A winning bonus bet typically pays out its profit only, not the original stake — that's why every verified pair nets roughly 90%, not 100%, of the matched amount.
DraftKings, Bet365, PrizePicks, and Underdog all require a small real-money qualifying wager before the bonus unlocks. Offsets between them are approximate — treat it as ~$25 of small, capped real-money exposure.
Anything requiring 2+ picks to all hit (PrizePicks, Underdog, both Sleeper offers) can't be matched into a fixed, guaranteed number the way a single 50/50 game can — and the hedge tool available (Courtside) isn't big enough to fully cover it. Treat that whole section as a range, not a lock.
NFL, NBA, and MLB tend to have more consistent lines and props across books than niche markets, making it easier to find a true match.
Books can and do limit or restrict accounts that repeatedly use promos this way. Read each book's terms — this can affect future offers and withdrawals.
