Race of Explorers is a special event that will be held occasionally and can be unlocked by all the players that are at least at level 40. The availability of the event can be checked by looking at the helipad in the park. Once available, Race of Explorers sends players to a remote island where they all participate in a search for the bones of the exclusive creatures. The island is pretty small – be quick and collect the bones before other players!
What are the circular waves in the Race of Explorers?
That’s your bone detector indicating a bone is nearby. A small circle means the bone is one tile away (also diagonally) from the place you’ve dug in. A large circle means the bone is two tiles away.
Use triangulation to better determine the exact spot.
