Accumulate imp tokens
Ether kingdoms is a mining strategy game with an object to accumulate imp tokens or imps. Players can send their imps into battle or use them as workers to mine more imp tokens. The game uses the Freemium model, so players can try the game for free in a tutorial mode and then choose if they want to buy some imps and continue playing the game.
You can attack another player to take a portion of his imps. The battles are automatic in turn based combat. You can also trade imps for loot boxes that contain random artifacts. Your remaining imps can use those artifacts to increase their stats in battle. More features include treasure hunts, boss fights, and the Far realms extension.
