Little mischief-maker with remote turned over lottery (6)
I believe the answer is:
raffle
'lottery' is the definition.
(I know that raffle is a type of lottery)
'little mischief-maker with remote turned over' is the wordplay.
'little mischief maker' becomes 'elf' (mischievous little creature).
'with' says to put letters next to each other.
'remote' becomes 'far' (synonyms).
'turned over' is a reversal indicator.
'elf'+'far'='elffar'
'elffar' in reverse letter order is 'RAFFLE'.
(Other definitions for raffle that I've seen before include "Lottery with bought tickets" , "charity event" , "Sweepstake" , "Fund-raising draw" , "Lotto" .)
