The Robot Island is a training island introduced in Update v5.0, replacing the former Prison Island. The island has training zones that are substantially better than the Main Island, Desert Island and Lost Sea Island. However, SS class is required to access the island and at least 10 Sp for the Strength, Endurance or Psychic stats respectively to train there.
As with all other game islands, the Robot Island has a chest called the Robot Chest which allows players to collect 10,000 
every 7 hours.
To the left of the island portal is the Boost Shop, marked by a building. Players may purchase in-game boosts for 25M 
each, with a limit of 20 per day. (Shop refreshes at 00:00 UTC).

Trivia[]
- Robot Island replaced Prison Island after v5.0, after it was pre-announced an event regarding aliens with a binary code on the old 10Sp Psychic Training Zone that said "Yes, this looks like the perfect place to begin our invasion...".
