If you see an emoji symbols in front of a garden name it most likely is to denote that the player is an active player. There are two groups for symbols:
- those who use weekly symbols that they change each Friday (depending on time zone and memory!)
- those who use monthly symbols (change once a month - for those who don't want to have to remember to change their garden name weekly)
After the weekly or monthly symbol, some people use symbols to indicate what gift they prefer (like lightening for energy, the airplane used to be for the Cretan PLANE Tree, some may be indicating the Festive Purple Tree with it now).
