A coin's tossed to decide where to play (6)

I believe the answer is:

casino

I'm a little stuck... Click here to teach me more about this clue!

'decide where to play' is the definition.
I can't tell whether this defines the answer.

'a coin's tossed' is the wordplay.
'tossed' indicates an anagram.
'a'+'coins'='acoins'
'acoins' with letters rearranged gives 'CASINO'.

'to' acts as a link.

Can you help me to learn more?

(Other definitions for casino that I've seen before include "You can win a fortune here" , "Where our betters show" , "Gaming establishment" , "Where some gamblers go" , "Gambling den" .)

I've seen this clue in The Globe and Mail.
