No. Most casual games are designed to be free to play. In-game purchases are usually for speeding up progress or obtaining special items, but they are not essential and can be enjoyed without spending money.
First check whether your device meets the minimum system requirements of the game. If the problem persists, try restarting the game or device. In addition, you can consult the in-game help document or contact customer service for support.
Most casual games automatically save progress to ensure that players do not lose data due to accidental exits. However, it is recommended to check the help guide of the specific game to confirm this.
Casual games are usually compatible with multiple platforms, including smartphones (iOS and Android), tablets, and some desktop operating systems. Please choose the appropriate version to download according to the information provided by the game store.
It may be because your device settings block automatic updates, or the update has not yet been released in your region. Check the settings in the app store and make sure the auto-update option is enabled.
Most games have reporting mechanisms that can be submitted directly through the in-game feedback system. Alternatively, you can visit the game's official website to find more information or contact the customer service team.
