About this game

You were once the great Demon King who ruled the demon world. But after a sneak attack by a cowardly hero, you lost all your power overnight and even turned into... an egg!

How could you accept such shame?

Great Demon King, it is time to gather your monster army again, rebuild your castle, and begin your comeback journey to take back everything that was once yours!

Features:

【From Demon King to Egg】
Start as an egg and keep evolving to regain your power. Collect demon eggs, recruit monsters and fallen heroes, and rise back to the top step by step.

【Easy Growth, Faster Star Upgrades】
Resetting a character returns the resources you used, so you can switch teams with no waste. Special card combos give double star-upgrade progress, helping you grow stronger faster.

【Strategy Card Battles】
Collect and train many different monsters to build your own army. Each character has a different role, so choosing the right team is the key to victory.

【Idle Rewards and Great Benefits】
Earn rewards even while offline. With free summons, daily rewards, and many game modes, it’s easy to grow stronger and keep up.

【Team Up and Farm Gear】
Join other players to challenge strong enemies, get better equipment, and improve your power. Fight together with friends and enjoy fun co-op battles.

【Rebuild Your Castle, Find the Truth】
As you rebuild the demon world, you will slowly uncover the truth behind the heroes’ invasion, regain your lost glory, and discover the secret behind this disaster.
