OG Promo Code Offer Details: Up to $100 in Bonuses for Knicks vs. Cavaliers Game 4
The OG promo code offer requires no code at all -- simply sign up as a new user and you are eligible to earn up to $100 in trading bonuses based on your cumulative trade and settle volume. The bonus unlocks in tiers, so the more you trade, the more you earn. Here is how the milestone structure breaks down:
- Trade and settle $10 to receive a $10 bonus
- Trade and settle $100 to receive an additional $15 bonus
- Trade and settle $250 to receive an additional $25 bonus
- Trade and settle $500 to receive an additional $50 bonus
With the Knicks holding a 3-0 series lead and Jalen Brunson averaging 29.0 points and 8.7 assists through three games, you could trade a "yes" contract on New York advancing to the NBA Finals. If the Knicks close out the Cavaliers in Game 4, your position settles in your favor and your payout appears in your account shortly after. If Cleveland manages to stave off elimination and your trade does not go your way, you can sell your contracts at the current market price before the event settles to limit your exposure.
There are a few important terms to keep in mind before signing up. This offer is available to new users in all U.S. states except New York and Arizona. Users in Illinois, Massachusetts, Maryland, Michigan, New Jersey, Nevada, and Ohio may claim the bonus but cannot use it for sports trading. You must be physically located in a legal OG state to participate, and the offer expires Dec. 31, 2026.
