For the Sears.com "2002 Olympic Winter Games" Sweepstakes, Oncall teamed up with Wunderman to create online "scratch and win" game pieces.  Customers making large appliance purchases were sent an email with a link to a game piece.  The game piece mirrored the physical scratch-off tickets. Depending on the customer's browser settings, a simple animation or an interactive game appeared, letting the customer reveal a winner.
