Boat Sinker is a simple game designed for kids on the Android platform. In this game, paper boats sail on a lake, and your task is to sink as many of them as possible within the given time limit. The game provides you with an infinite number of rocks to throw at the boats, and you can choose from different types of rocks.

One interesting feature of Boat Sinker is the presence of sodium metal rocks. These rocks explode after entering the water, taking out multiple boats at once. However, you have a limited supply of sodium metal rocks, so you need to use them strategically.

Apart from rocks, you also have a limited number of rockets that can be used to sink the boats. If you run out of rockets or sodium metal rocks, you can restock them by watching a short video using the Wildcard button.

Overall, Boat Sinker is a simple yet enjoyable game for kids. It offers a variety of rocks to throw, including explosive sodium metal rocks, and challenges players to sink as many paper boats as they can within the time limit.
