Tall tale of Bob playing pub game (5,8)
I believe the answer is:
table football
'pub game' is the definition.
'table football' can be an answer for 'game' (I have seen 'Indoor game ' mean 'table football' so perhaps 'game' could also mean 'table football'). I am not certain of the 'pub' bit.
'tall tale of bob playing' is the wordplay.
'playing' indicates an anagram.
'tall'+'tale'+'of'+'bob'='talltaleofbob'
'talltaleofbob' anagrammed gives 'TABLE FOOTBALL'.
Can you help me to learn more?
(Other definitions for table football that I've seen before include "Game played with model players attached to metal rods aiming to score goals" , "Game with revolving soccer players!" , "Indoor game" .)
