How to play on a mobile device

The developers are working on optimizing the game for mobile browsers. But currently, the best way to play Hero Wars: Dominion Era is on a PC. 

If you wish to play Hero Wars: Dominion Era on mobile devices, there are two possible solutions:

  1. You can launch the game in most mobile browsers, e.g., Google Chrome or Safari. However, stable performance is not guaranteed for now because the game was not designed for mobile devices.
  2. You can start from scratch in the mobile game Hero Wars: Alliance. Open Google Play Market, AppStore, or AppGallery, type "hero wars" in the search bar, and install the game.

Hero Wars: Alliance is developed by a different team and has different game mechanics, so there is no progress synchronization between the two versions of the game. If you have an account on a PC and download the mobile app, you will start a new account.
