Trade & Get Up to $100
OG Promo Code Offer: Up to $100 in Bonuses for Brazil vs. Japan
The OG promo code offer requires no code at all. Simply register a new account and begin trading to unlock bonuses in stages based on your cumulative trade and settle volume. Brazil vs. Japan is a strong place to start, with plenty of contracts available around the match outcome, total goals, and more.
Here is how the bonus 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
Your first trade on the Brazil vs. Japan market gets you started toward that initial $10 bonus. If you buy a "yes" contract on Brazil to advance and the result goes your way, your position settles in your favor and that volume counts toward your milestone. If Japan pulls off the upset and your Brazil contract does not settle as expected, that trade still counts toward your cumulative volume total, keeping you on track for future bonuses.
A few key terms to keep in mind before claiming. The 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 apply it to sports trading. You must be physically located in a legal OG state to participate. The offer expires Dec. 31, 2026.
