eBay partnered with Harrah's to help cross-pollinate their respective target markets. For their part, eBay hosted an online instant win game as an overlay to the Harrah's Treasure Hunt game.  Casino patrons received a welcome kit that drove them to eBay, where they played the instant win game - trying to match the items contained in three treasure chests.  A second chance sweepstakes provided the chance to participate in the Harrah's $1,000,000 Treasure Hunt to find real treasure chests scattered throughout the Las Vegas Strip.
