Sign up for each book, claim its bonus, then bet that bonus on opposite sides of the same market across two books. One side wins — that's your profit.
These numbers cover the Verified Pairs section only. There are two more sections below: Experimental (marked for advanced users, worth roughly $100–$191 depending on outcome) and Daily Match (Fanatics, worth up to $342 over 10 days using real recycled cash rather than one-time bonus credit). Read each section fully before depositing.
Sign up, claim each book's bonus, then bet it on opposite sides of the same close-to-even market across two books. One side wins; the losing side only cost free credit, not your own cash.
Sign up and deposit the minimum required on each book. Most bonuses land automatically after the deposit or qualifying bet clears.
DraftKings, Bet365, PrizePicks, and Underdog each require a small real-money wager before the bonus unlocks.
Look for the same market — game, line, or player prop — listed on both books you're pairing, at odds close to even.
One side wins. A winning bonus bet pays its profit only, not the original stake back — that's already factored into every estimate on this page.
Every book, what it costs, and where it's used.

| Fliff | $100 | Up to $100 (100% match) | No | Pair 3 |

| Courtside | $10 | $50 | No | Experimental (straight-leg hedge) |
| Fanatics | $10 min, then real wagers | Up to $1,000 (10 × $100/day) | Yes — real cash, daily | Daily Match |
Confirm current terms directly with each book before depositing — promo structures, minimum odds, and amounts change often and vary by state. Onyx Odds shows either the $50 bonus-picks offer or the $100 deposit-match offer depending on your account — check your Promotions tab to see which one you have.
Each pair bets the same market on opposite sides across two books, so one side always wins.
This section uses a 2-pick parlay on four different apps, one per possible outcome of a single shared prop, so every outcome pays.
Step 1 — Pick a shared prop with two legs
Choose two players with a clean over/under line — for example, Pitcher A over/under 4.5 strikeouts and Pitcher B over/under 4.5 strikeouts. Confirm the same line is listed on all four apps before placing anything.
| App | Bet | Combo covered |
|---|---|---|
| Sleeper ($100 match, 2-pick entry) | Pitcher A over 4.5, Pitcher B over 4.5 | over, over |
| PrizePicks ($50, 2-pick Power Play) | Pitcher A over 4.5, Pitcher B under 4.5 | over, under |
| Underdog ($50, 2-pick Standard) | Pitcher A under 4.5, Pitcher B under 4.5 | under, under |
| Onyx Odds ($50 bonus picks, 2-pick entry) | Pitcher A under 4.5, Pitcher B over 4.5 | under, over |
Step 2 — Add two straight bets for extra profit in every outcome
Use Courtside's $50 bonus and DraftKings' $50 leftover bonus (from Pair 1) as straight, single-leg bets — not a parlay. Put $50 total on "Pitcher A under 4.5" (split however you like between the two apps) and $50 total on "Pitcher B over 4.5." These pay independently of the parlays above, adding extra profit whenever either leg lands.
| Actual result | Parlay that hits | Straight-bet legs | Total |
|---|---|---|---|
| A over, B over | Sleeper: $100 | "B over" wins: ~$45.45 | ~$145.45 |
| A over, B under | PrizePicks: $100 | neither leg hits: $0 | ~$100 |
| A under, B under | Underdog: $125 | "A under" wins: ~$45.45 | ~$170.45 |
| A under, B over | Onyx Odds: $100 | both legs win: ~$90.90 | ~$190.90 |
Steps
Whichever branch pays out through Courtside's straight-bet legs, that money carries a one-time playthrough requirement before it's withdrawable. Clear it with one hand of covered baccarat in Courtside's casino:
Fanatics matches your daily wager in FanCash the instant you place it, win or lose, up to $100/day for 10 straight days.
The daily play (repeat for 10 straight days)
| Outcome | Real $100 (Team A) | Bonus $100 (Team A) | Hedge $147.62 (Team B) | Net |
|---|---|---|---|---|
| Team A wins | +$90.91 profit | +$90.91 profit | −$147.62 | $34.20 |
| Team B wins | −$100 | $0 | +$134.20 profit | $34.20 |

A few things that affect the real outcome, not just the headline number.
Same game, same market, same number — small differences between books break the hedge.
A winning bonus bet typically pays its profit only, not the original stake — every estimate on this page already accounts for that.
DraftKings, Bet365, PrizePicks, Underdog, and Fanatics all require some real cash at some point. Read each section's math before depositing.
The Experimental section requires four separate parlay entries plus two straight bets, all on the same shared prop. Double-check every leg before submitting.
Bet equal amounts on Banker and Player in one hand — you'll keep 95% to 100% of your stake regardless of outcome, useful for clearing playthrough requirements cheaply.
Books can and do limit or restrict accounts that repeatedly use promos this way. Read each book's terms.
