Raffle (5)
I believe the answer is:
lotto
'raffle' is the definition.
(thesaurus)
This is the entire clue.
(Other definitions for lotto that I've seen before include "Prize draw" , "Game of chance based on numbered balls being drawn at random" , "Bingo-like game" , "National game with large money prizes" , "Children's game, housey-housey" .)
