DraftKings Sportsbook King of the Diamond Promo

DraftKings Sportsbook is back at it with its 'King of the ____' series of promos, this time catering to baseball fans with its new 'King of the Diamond.'

Previously, DraftKings ran promos called 'King of the End Zone' for the NFL and 'King of the Court' for the NBA seasons, respectively. It's no surprise that it has adapted the extremely successful promotion theme to the MLB.

With King of the Diamond, just like the previous versions, DraftKings Sportsbook users compete for a share of $1,000,000 on a weekly basis.

When bettors opt into the promo and create an eligible parlay, they are entered in the million-dollar prize pool in hopes that their selected player(s) will become King.

King of the Diamond is focused on player home run parlays. Select 2-5 players that you think will hit a home run for the highest scoring team that day, and place at least $5 on that qualifying parlay.

As a bonus, your initial parlay also receives an odds boost when the qualifying token is applied!

How does the King of the Diamond Promo Work?

You may still be wondering exactly how the King of the Diamond Promo works, so here is an explanation broken down by each step!

  1. Place a $5+ Player Home Run Parlay
    Choose 2-5 players to hit a home run as part of your boosted parlay. This bet must be at least $5 to qualify ($25 max).
  2. Watch the Games Play Out
    If your chosen player(s) hits a home run and their team finishes as the highest-scoring team of the day (or ties), they become a King of the Diamond.

  3. Split the $1 Million Prize Pool
    If your pick is one of the winning players, you’ll earn a share of the $1 million bonus bet pool, split evenly among all bettors who chose correctly.

  4. Get Paid, Even If Your Full Parlay Loses
    Your full parlay doesn’t need to hit. As long as you picked a player who becomes a King of the Diamond, you still win bonus bets.

DraftKings King of the Diamond Rules

Here are some rules and scenarios to help you understand the King of the Diamond promo:

  • Only Home Run Hitters on the Highest-Scoring Team Qualify: A player must hit at least one home run and play for the highest-scoring MLB team (from eligible games) to be named a “King of the Diamond.”
  • Multiple Players Can Win: If multiple players on the top-scoring team hit home runs, all of them are considered Kings of the Diamond. Anyone who wagered on any of those players will split the prize pool.

  • Tied Teams Count: If two or more teams tie as the highest-scoring on the slate, all HR hitters from all tied teams qualify as Kings, and bettors who picked them will share the jackpot.

  • Equal Payout, Regardless of Entries: Picking more than one winning player does not increase your share. All eligible bettors split the prize equally, even if some picked multiple winners.

  • Fallback Rule: If the highest-scoring team had no home run hitters, DraftKings will look to the next-highest-scoring team, and continue down the list until at least one qualifying HR is found. Voided parlay legs do not disqualify entries if valid HR legs remain.

  • Eligible Games: Only MLB games that started at 6:00 p.m. Eastern Time are eligible for King of the Diamond. That means if the highest scoring team was from a 1:00 p.m. game, none of their players are eligible to win, and it will go to the highest scoring team out of the eligible games

Strategy for DraftKings King of the Diamond

There is a lot of strategy that comes with creating a qualifying parlay for King of the Diamond.

You have to factor in whether it is more important to you to give your initial bet a chance to win, or go for the longshot of picking the King of the Diamond winner.

Since your qualifying parlay doesn't have to win in order for your bet to remain eligible, creating a 5-leg parlay gives you more chances at picking the King. However, it is also much harder to win your initial bet than if you had made a 2-leg parlay.

Remember, your qualifying bet is boosted by up to 50%, so even if you don't pick the King, you can still win a juicy home-run parlay!

King of the Diamond Pro Tip:

Since the bonus bet payout is split among everyone who picks the correct player, choosing a less popular or under-the-radar player can lead to a much bigger reward.

Many bettors will be betting on players such as Aaron Judge or Shohei Ohtani, so the bonus bet awarded if those players win is much smaller. While that's nothing to complain about, it can be fun to pick a player that fewer people will bet on.

For example, when Pedro Pages of the St. Louis Cardinals won King of the Diamond, the 12 people who bet on him got bonus bets totalling a whopping $83,000!
