Existing users at bet365 had the chance to enter a bracket challenge to win up to $10 million if they got every game correct. It is also providing daily odds boosts for the NCAA Tournament, which typically come in at 30% or 50%.

Caesars Sportsbook Tournament Pick’Em

On 10 different NCAA Tournament game days, you can make five picks at Caesars Sportsbook with a chance to win a share of $5 million in bonus bets.

Unlike Caesars Flips, where you reveal a pick that’s given to you each day, Tournament Pick’Em allows you pick either side of five bets — for free — and the more you get right, the bigger bonus you will receive.

Lower win totals get you profit boosts, but if you win 30 picks over the 10 days, you get a $25 bonus bet. That jumps to a $100 bonus bet at 35, $1,000 bonus bet at 40, $10,000 bonus bet at 45, and the share of $5 million if you get all 50 correct.

New customers claiming the Caesars Sportsbook promo code can Bet $1 and get 10 100% profit boosts.
