The Year 400 events were dominated, as usual, by the Championship Games, in which Reiye (unexpectedly) dominated, winning the Tumble Race, the Bandersnatch, and coming third in the Quiz. As well as the Championship Games, there were a number of other events, such as: the introduction of King of the Hill, a lottery, a master riddle, and a number of egghunts, foozles and a treasure hunt.
