Bad blood I attracted at first in game (7)
I believe the answer is:
diabolo
'game' is the definition.
(I've seen this before)
'bad blood i attracted at first' is the wordplay.
'bad' indicates anagramming the letters.
'at first' says to take the initial letters.
The initial letter of 'attracted' is 'a'.
'blood'+'i'+'a'='bloodia'
'bloodia' anagrammed gives 'DIABOLO'.
'in' is the link.
(Other definitions for diabolo that I've seen before include "Game of catching spinning-top" , "juggling performance?" , "Game involving sticks and spinning top" , "Top-on-a-string game" , "Devilish" .)
