How the Caesars Sportsbook promo code works for Mariners vs Tigers Game 4

To claim the Double Your Winnings deal, new bettors must enter the Caesars Sportsbook promo code COVERS20X during sign-up and deposit at least $10. This code is your ticket to a boosted start, letting you tap into extra value on your Mariners vs Tigers Game 4 wagers.

Once you have registered and made your qualifying deposit, place a first bet of $1 or more. After this initial wager settles, Caesars will credit your account with 20 profit boost tokens, each offering a 100% profit boost. These tokens can be used on future eligible wagers, not your first qualifying bet. Whether your initial pick wins or loses, you will still receive all 20 tokens for upcoming bets.

Here are the essential token details:

  • Each token is worth up to $2,500
  • Maximum wager of $25 per token
  • 14-day validity period for using tokens
  • Minimum odds requirement of -10,000
  • Tokens must be used individually (cannot be combined)
  • Bonus amounts are not included in winnings
  • Offer not available in all states

Remember, profit boost tokens become available only after your first qualifying bet settles, giving you more opportunities to double your winnings on future bets, including the rest of the postseason action.

How to claim your Caesars bonus for Mariners vs Tigers Game 4

Ready to double your winnings as the Tigers and Mariners battle for a spot in the ALCS? Here is how to get started and maximize those 20 profit boosts:

  1. Register: Create your Caesars Sportsbook account using the promo code COVERS20X
