This is an online game using the Unity3d engine. It's on Disney's website, and is based on the fictitious arcade game called Sugar Rush in the movie Wreck it Ralph. The unlock code for King Candy in the English version of this online game is well known as "king candy". But his unlock code for the Japanese version of the game is different. I managed to hack into the game's data and find the cheat code for the Japanese version of the game.
The unlock code King Candy in the Japanese version of the game is "7eleven".
