Black Gold Plumber
Black Gold Plumber is an interesting Plumber-style puzzle game in which you have to connect pipe pieces to build an oil pipeline. To start, press the green arrow button and "1" in the list. An oil well will open in front of you, from which you need to lay a pipeline to the pipe below. Click on the fragments scattered on the field to rotate them to the right side and put them into a common system. If you need to mix the fragments, click the twisted arrows on the left. Keep within the allotted time: it counts down the black timer scale at the top.
