To put many first in a game of chance (5)
I believe the answer is:
lotto
'game of chance' is the definition.
(I've seen this before)
'to put many first' is the wordplay.
I cannot quite see how this works, but
'to' is found in the answer.
'many' could be 'lot' (a lot of something) and 'lot' is located in the answer.
No letters remain.
This explanation may well be incorrect...
'in a' acts as a link.
Can you help me to learn more?
(Other definitions for lotto that I've seen before include "Game in which numbers are drawn" , "National game with large money prizes" , "Housey-housey, bingo" , "Bingo - Venetian painter" , "Lucky draw" .)
