Game with tiny, subtle signals (11)
I believe the answer is:
tiddlywinks
'game' is the definition.
(I know that tiddlywinks is a type of child\\u0027s game)
'with tiny subtle signals' is the wordplay.
'with' means one lot of letters go next to another.
'tiny' becomes 'tiddly' (I've seen this before).
'subtle signals' becomes 'winks' (I can't justify this - if you can you should give a lot more credence to this answer).
'tiddly' next to 'winks' is 'TIDDLYWINKS'.
Can you help me to learn more?
(Other definitions for tiddlywinks that I've seen before include "Game of flicking disks" , "Game of flicking counters" , "Children's game" , "Counter-flipping game" , "Game of flipping counters" .)
