What is the Bet9ja promotion code? It is YOHAIG. Enter it during registration, verify the account, then deposit at least N100 to trigger the welcome offer. Bet9ja matches the first deposit at 100%, up to N100,000. Withdrawal requires 10x rollover on selections at minimum odds of 3.00 within 30 days, so short-priced favourites make no progress. New accounts only. 18+, T&Cs apply.
