| Eligibility | 18+, US resident with valid SSN |
Polymarket is the largest event-contract platform available to US users, with markets spanning NFL, NBA, MLB, NHL, college football and basketball, soccer, tennis, and more. New users who deposit $10 or more through code MRGAMB get a $20 trading credit added automatically.

New users who enter code MRGAMB, place a $5 pick, and let it settle get $50 in Free Play credited automatically, no separate claim step required. Fliff’s sweepstakes redemption footprint has narrowed in 2026 as more states pass their own sweepstakes laws, so it’s worth checking current state availability before you sign up.

New sportsbook users who enter code MRGAMBLE, deposit between $10 and $100, and complete verification get that deposit matched dollar for dollar in Rebet Cash, up to $100. Rebet also runs a separate casino offer (code GAMBLE, 50% match up to $50) for players more interested in slots and table games.
Betr Promo Code: First Entry Backed Up to $100
| Promo Code | MRGAMB |
| Welcome Offer | First entry backed up to $100 (No Sweat) |

| Refund Type | Betr Bucks, 1x playthrough, expire in 30 days |
| Format | Pick’em (DFS) |
| Eligibility | 21+ (18+ in AL, 19+ in CO) |
Betr leans pick’em rather than prediction-market pricing, built around choosing whether a player finishes over or under a projected stat line. New users who sign up with code MRGAMB get their opening entry backed up to $100, if it doesn’t hit, Betr returns the stake as Betr Bucks instead of a straight loss.
