>>>INSTRUCTIONS<<< Click on the country to earn coins, clicks, and contribute to the global scale. Click the white coin icon to unlock new countries. You can change skins (when you own them all) by clicking the desired skin. When in the country skin shop, you must buy the items in this order: Yugoslavia, Ottomans, Czechoslovakia, Qing Dynasty, Roman Empire. If you don't buy them in the order, it will lag. Once you open the shop, you cannot close it. Click on the volume icon to stop or start the music. When clicked, the icon does not stop the popping sound on the country.
