About this game

Introducing "Dam Builder," a super casual idle game where you embark on the journey of constructing a dam! Begin with a small dam on a serene lake and gradually expand it into a massive structure. Earn profits by releasing water from the dam. Upgrade each section of the dam individually to increase your earnings. As you progress, unlock a bustling dock in the upstream lake after constructing Dam 2. Once the dock is unlocked, you'll automatically acquire a fishing boat. Send the fishing boat out to the lake, catch fish, and transport them to the dock for additional profits. Use diamonds to unlock new fishing boats and expand your fishing fleet. Dive into the tranquil world of "Dam Builder" and witness your empire grow along with the expanding dam!

Game would be fun if it wasn't completely overloaded with ads. It's not just ads to advance faster, it's ads when you upgrade the supplemental income areas, or when you have an achievement. Oh, you upgraded the frequency of special rewards for your dam? Guess what, you have to watch an ad for every single one. This developer is not trying to make a fun game, they are adding a little game play to their commercial app.

I like this game and what it represents. I'd really like to see an expansion in the game play. Unfortunately, there only seems to be three worlds in which to build dams and once all the dams are built and limited upgrades attained, that's pretty much it. One can increase the efficiency and profitability of the industries all day long, but once the last dam is maxxed out and the third boat is purchased, the game just stops all forward momentum and there's no longer any point to playing.

It's fun. I take it back, ads are forced and intrusive. add a way to use in game $ to pay for the dam stage upgrade "reset." Right now the only way to reset to the next dam stage is to watch an ad, and it says "free". If you kept that, but just added a second button allowing use of the in game money, people will have a way to play without ads if they so wish. Blocking it behind an ad just means you can't progress the dams. Any big buy rewards you with another ad. Ads ads ads. ADS EVERYWHERE
