DraftKings is a popular daily fantasy sports and sports betting platform. The bonus bet feature on DraftKings is a type of promotional offer that provides users with additional betting value. Here’s how the bonus bet typically works on DraftKings:

1. **Receiving Bonus Bets**: Users can receive bonus bets through various promotions. This could be part of a welcome bonus for new users, a reward for existing users, or a special offer tied to a particular event or sports season.

2. **Using Bonus Bets**: Once you have bonus bets available in your account, you can use them to place wagers on sports events. The process is similar to placing a regular bet, but with the added benefit that you’re not risking your own money.

3. **Bet Placement**: When placing a bet with a bonus bet, you’ll typically select the event you want to bet on, choose the type of bet (e.g., moneyline, spread, over/under), and enter the amount you want to bet. The platform will then apply the bonus bet funds to your wager instead of your cash balance.

4. **Potential Winnings**: If your bonus bet wins, the payout will be calculated as if you had placed the bet with cash. However, the actual winnings you receive will typically exclude the amount of the bonus bet itself. For example, if you place a $10 bonus bet and win $50, you’ll receive $40 in profit (the $10 bonus bet is not returned).

5. **Restrictions**: Bonus bets may come with certain restrictions, such as expiration dates, minimum odds requirements, or limitations on the types of bets you can place with them. It’s important to read the terms and conditions of the bonus bet offer to understand any limitations.

6. **Conversion to Cash**: In some cases, bonus bets may need to be rolled over a certain number of times before any winnings can be withdrawn as cash. This is known as the rollover requirement, and it varies depending on the promotion.

7. **Taxes**: Winnings from bonus bets may be subject to taxes, depending on the laws in your jurisdiction and the amount won.

It’s important to note that the specifics of how bonus bets work can vary, and the information provided here is a general overview. Always check the latest terms and conditions on the DraftKings platform for the exact details of any bonus bet offers you are considering.
