くるくるれーる is a thrilling and suspenseful puzzle game where you must connect train tracks to prevent the train from derailing. Each stage presents a grid of scattered tracks, and it's your job to touch and connect them in order to change their color and create a clear path for the train to pass through. The train starts at the designated starting point and continues to run until it reaches the goal, which then becomes the starting point for the next stage.

At the beginning of each stage, the train moves slowly, but once it passes the starting point, it accelerates! Take this opportunity to carefully observe the entire stage and plan the best route to the goal. However, even if the train has already accelerated, you can still connect the tracks in a loop to prevent it from derailing. Take your time to think strategically while the train is circling around.

Be careful not to run out of fuel though. The train emits smoke, and when the smoke becomes smaller, it indicates that the fuel is running low. If you reach the goal before running out of fuel, a certain amount of fuel will be replenished, ensuring that you can proceed to the next stage without any problems.
