The latest Curiosity update is the biggest in the experiment’s history. This update, which is only available on Android at this point, fixes the longstanding issue with disappearing coins, and one of the main culprits behind the vanishing coin issue.
22cans removed the Facebook login button from the top right of the game’s display. In the past, pressing this button would open a Facebook connection page, but it would also erase your coins. Other technical issues that led to coin loss has also been eliminated.
You may also notice improved server stability. That’s probably the biggest update of all since the game is useless without its servers.
