My kids have exchanged friend codes, and received gem bonuses.
How can they visit each other's islands?
Note:
Under social, there's a "Friends" pane that always reads "3 gifts available", but has no other entries other than "visit random island". The "gifts" tab is similarly blank. This is on a Kindle Fire HDX, with no Facebook accounts.
Best Answer
To give gems to friends, and to visit friends worlds in Dragonvale, the player must connect the game to Facebook, and must be Facebook friends with the people they want to give gems or visit their friends parks.
The "visit random park" button will randomly pick a park the player can already visit. If the player has no parks to visit normally, then the "visit random park" will fail.
