'game' is the definition.
(ball game)

'magistrate's absorbing day given party' is the wordplay.
'magistrate' becomes 'doge' (doge is a kind of magistrate).
'absorbing' means one lot of letters goes inside another.
'day' becomes 'd' (abbreviation for day).
'given party' becomes 'ball' (ball is a kind of party. I am not sure about the 'given' bit.).
'doge' placed around 'd' is 'dodge'.
'dodge'+'ball'='DODGEBALL'
