Draw spirit miles up (6)
I believe the answer is:
raffle
'draw' is the definition.
(I've seen this before)
'spirit miles up' is the wordplay.
'spirit' becomes 'elf' (I've seen this before).
'miles' becomes 'far' (I am not sure about this - if you are sure you should believe this answer much more).
'up' says the letters should be written backwards (in down clue: letters go upwards).
'elf'+'far'='elffar'
'elffar' reversed gives 'RAFFLE'.
Can you help me to learn more?
(Other definitions for raffle that I've seen before include "Lottery with goods as prizes" , "Fund-raising draw" , "Sweepstake" , "Form of lottery" , "Prize draw" .)
