The agency won the business following a pitch process against Karmarama and the incumbent Albion.
WCRS has been appointed as King looks to expand globally. The company says it will continue to work with Albion on a number of games across its portfolio. Albion has worked with the games company since 2011.
Nicki Sheard, VP Brand Marketing, King, said, "After a competitive pitch with excellent work from all agencies involved, we have appointed WCRS to our agency roster.
"We were extremely impressed with their combination of strategic rigour and creativity and can’t wait to embark on the next stage of King’s exciting journey with them.’
Julian Hough, Chairman at WCRS, said, "We are absolutely delighted to be working with one of the most exciting companies in the world right now."
