This is a casual game. Both sides need to do their best to protect their own castles and find ways to destroy the other side's castle to win. At the bottom of the screen of the game interface, there is an energy bar, and above it are the types of soldiers that players can summon and the types of defensive fortresses that can be built. As the game progresses, the energy bar will continue to accumulate energy. At this time, the player can draw lines on the screen. The shape of the drawn line segment will determine the formation of the generated soldiers, or build a defensive fortress with the same shape. It should be noted that the amount of energy in the energy bar directly limits the length of the line segment drawn, which in turn affects the scale and strength of the summoned creature or defensive building. Players must cleverly plan the use of energy, reasonably draw line segments, create a favorable battle situation, and defeat their opponents!
