TAMBA will be creating a viral game, which is due to launch in August, to increase brand awareness and drive traffic to SockShop.co.uk.
Originally a global high street brand, Sock Shop was sold to the Ruia Group in 2006 and become an exclusive online retailer, specialising in socks and hosiery.
The Sock Shops microsites are currently being created for its own sub-brands as a means of offering customers bespoke ways of shopping online.
Cassie Ash, marketing manager at SockShop.co.uk, said: "We are confident that a viral game will create an online buzz about SockShop.co.uk; introducing new customers to our wide range of products and customer service.
"TAMBA is hugely experienced in the viral industry, and presented us with creative gaming ideas that represented our products and will highlight SockShop.co.uk's role as a popular online retailer."
TAMBA's previous clients include E-ON, Sony Blu-Ray, Lovefilm, Kwik Fit and Virgin Active.
