Playing Clash of Clans on multiple accounts can be a great way to experience the game from different perspectives, try out new strategies, or simply have more fun. There are a few different ways to do this, but the most common is to create multiple Supercell IDs.
Supercell ID is a free account system that allows you to save your progress in Clash of Clans and other Supercell games. Once you have created a Supercell ID, you can use it to log into the game on any device. This means that you can have multiple Clash of Clans accounts on the same device, or you can access your accounts from different devices.
