Picker 3D uses a picker to collect selective items on the road. The goal is to complete the tasks of each level by collecting enough required items.
You will adjust the direction for a picker so that it collects everything on the road such as medicine, sugar, candy, ect. Collect all of them on the road to complete the challenge requirements.
However, not all of them can be collected such as bombs, iron, ect because it will cause your picker to break. Collect selectively on the road, complete as required to unlock other challenges.
