The Lord of the Games (aka LOG) is tired of the petty squabbling between Banjo and the evil witch Gruntilda (aka Grunty) over the years, and has arranged a showdown to decide the rightful owner of Spiral Mountain. Claiming to have created every video game ever made, LOG has built the game worlds in which the contest’s challenges take place. Banjo must complete LOG’s challenges to win, while Grunty tries to stop him using every method her devious mind can muster.
