The online casino aims to recruit customers from the sites' sports and betting user base.
Sportinglife.com and bettingzone.com, which is powered by the sports site, will feature banner ads and links to drive users to the 32Red site (www.32Red.com).
Mary McGregor, sales and sponsorship director at Sportinglife.com, said it was an important place for 32Red to be to gain exposure to its predominant audience of ABC1 males.
The Sportinglife web site family, owned by ukbetting, includes Teamtalk and Totalbet.com.
