The game's main scope is on one hand for the user to build robust structures under a predefined earthquake. And on the other hand to learn about structural dynamics and seismic structural behavior. If the structure is stable will start to shake from its base. The buildings can consist from various structural elements such as bars and dampers. Each of the numerous stages in progression of the game have some limitations in structural height or geometry. Those limits are for the user to learn engineering principles. You will learn that a dynamic system the stronger it gets the more the mass it has. The mass many times is detrimental in terms of structural resilience or damping. You are invited if you are struggling to check also the simulation sector of the game where you can check your drawn design under ground movement excited by your own touches. This is very helpful for learning purposes and a tutorial for any stage you might be struggling with. Also, there is a button that after you watch an advert it shows you which part of your building is weak. The game gets frequently updated and continuously new stages are added.
