Clash of Clans and Winning Eleven at Yeongdeungpo Times Square

Last weekend I noticed that Clash of Clans (Mobile game) and Winning Eleven Online 2014 had invaded the Yeongdeungpo Times Square department store.I wonder what is Supercell's budget for those Clash of Clans ads (everywhere), but apparently it had at least some effect, as the game is currently No. 1 Top Grossing on the Apple App Store and No.9 on Google Play.
