The main objective in Dam Builder is to construct a dam that can withstand various water pressures while managing resources effectively. Players must strategically place materials and plan the dam's structure to prevent floods.

Points are earned by successfully building dams that hold back water and by completing challenges within the game. The better the dam's performance and design, the more points you accumulate.

You'll need various resources like wood, concrete, and metal to build your dam. Each material has different properties, affecting the dam's strength and durability, so choose wisely.

Water pressure mechanics are essential in Dam Builder. As water levels rise, the pressure on the dam increases. You must reinforce weak points and monitor water levels closely. Steps to manage pressure include: 1. Assess current water levels. 2. Identify weak spots in your dam. 3. Reinforce those areas with additional materials. 4. Continuously monitor water levels and adjust your strategy.

To unlock new building materials, you need to complete specific levels and challenges in the game. Each level may provide rewards in the form of new resources, which can help you enhance your dam-building strategy.
