Between each wave, you have the opportunity to merge identical pieces to upgrade your structures, making them stronger.
In this game, you'll encounter incredibly intriguing and engaging merging levels. You'll merge posts and upgrade them to become more powerful, leading you to more captivating and challenging levels.
The game offers incredibly engaging strategies. You should plan your kingdom with the most refined and optimal tactics to develop and protect your realm effectively.
