Things get a bit more interesting in what many described as a friendly rivalry between two Las Vegas casino operators.

Casino owner Derek Stevens dared his rival Tilman Fertita to a US$1 million bet on the winner of the NCAA men’s basketball tournament.

Stevens posted a copy of his betting slip from the Golden Nugget on Twitter.
