Kawaii Mansion is currently available for Android 5.0 and above, RAM 2GB (or higher for better game experience)
iOS 10.0 RAM 2GB.
Stable Internet connection is required in order to play the game.
Make sure that you are connected to a steady Wi-Fi network. Keep in mind that if you are connected via mobile data (3G/4G) and the connection bars are full, it does not always guarantee a solid Internet connection.
Networks can slow down or get overloaded at times, especially when you are playing in a moving vehicle or the network base station is too far away from your location.
However, you can still play Offline (but there are limited features that cannot participate).
