I always received 2 Gold when winning on snail game in others gardens . I just read that at completion of the 10 herbal elixirs you receive 5 gold  ??? I have never received 5 why ??? yet this is what it says.
Copied and paste -
Congratulations, June and *Ella* Australia on successfully creating all 10 Magical Elixirs of Fairyland in Herbalism!
Turn Snails into 5 Gold every time!
Found a Snail in another Garden while out and about with the watering can? With *Ella* Australia's new powers, it can now be turned into 5 Gold every time!

They are referring to reviving plant and the snails you get.

Do you use gold to revive the wilter? If you use gold, it costs you 2 gold, so you would only see an increase of 3 onto your gold total.

Ahhh, I misread what you stated. Yes, snail racing games will always give two gold for the red and brown snails.

Tks for your comments Shannon and Jen, but sorry i really cant see that - as it states clearly and this is copied and pasted from page  :- Congratulations, June and *Ella* Australia on successfully creating all 10 Magical Elixirs of Fairyland in Herbalism!

That to me reads  -   Find a snail in a garden get 5 gold Every Time regardless  if its a game in another garden or if its revive and get a snail

Hi June, Snail Racing is different to finding a snail. If you read the info next to the "Find Snails" heading on the "Find Gold" page, it states the following.

"Find A Snail!
If you stumble upon a wilting plant in a public Garden, then upon reviving it you might be lucky enough to find a snail worth a few Gold!

To ensure that everyone gets a fair chance at finding snails, there are a couple of limitations: (1) after finding one, it won't be possible to find another for at least another 3 hours, and (2) they only appear in public Gardens, never in Private gardens."

The key phrase is the Wilting Plant.

Ok yes see your point thanks Jen but i think it should read in the Herbalism .. find a wilting plant and water to receive the 5 gold from a snail - not just find a snail in a garden etc ... Tks for your time and input

I see your point, but the revive a snail preceded the Snail Races. So it's possibly something that Mike and the Dev team can look at to clarify.  :)
