One of the best DraftKings promo codes is the first bet matched. This applies to first-time users when they make their first bet at DraftKings Sportsbook. For example, if your first bet is $100, you will get $100 in free bets instantly added to your DraftKings account in the form of bonus bets. DraftKings has a max of $500 in first bet bonuses.
Also, DraftKings has a deposit bonus. This gives new users a 20 percent match on deposits up to $500. So if you deposit $2500, you would earn a $500 bonus when you begin playing.
