CivIdle's base game is completely free. However, running the game's server costs money and if you'd like to help me keep the game's server running, you can purchase this optional supporter pack.

In-Game Benefits

• A unique badge for supporter pack owners that is shown in the in-game chat, player trades and world trade map tile
  
• Choose a custom color for your name in the in-game chat and the trade map tile
  
• Your name will appear in the wonder Hagia Sophia (three random supporters will be shown every time the wonder is clicked)
  
• You can skip the antibot/spam play time requirement (48-hour play time) when upgrading from Tribune to Quaestor

Every week, one of the supporter maps is available for all players. As a supporter pack owner, you have access to all supporter maps at any time
