Swipe a direct, downward path from the initial ball drop point towards the first (leftmost) truck.
The balls flow into and fully fill the leftmost truck (observed around 00:06).
Extend the existing path, or dig a new branch, leading towards the second (middle) truck.
The balls flow into and fully fill the middle truck (observed around 00:08).
Dig a wide, curving path that goes around the large central structure to connect to the third (rightmost) truck.
All remaining balls successfully travel along this path and fully fill the rightmost truck, triggering the 'LEVEL COMPLETE!' screen (observed around 00:13).
Q: What is the optimal path to fill the trucks?
A: Based on the video, starting with the leftmost trucks and then navigating a wide, looping path around the central obstacle for the final truck appears to be an effective strategy.
Q: Is there a specific order to fill the trucks?
A: The video demonstrates filling the trucks from left to right. While the primary objective is to fill all three, following this order allows for a logical progression of digging paths without hindering later ball flow.
