Feel like a real driver on the Braindoku road!
Road signs can only be removed with the line, the direction of which is shown on the blocker. There 4 types of road signs:
Horizontal - can only be collected as a part of the horizontal line;
Vertical - can only be collected as a part of the vertical line;
Circular - can only be collected as a part of the 3x3 section;
Crossroad - can only be collected if it's a part of a horizontal and vertical line simultaneously.
Drive safe!
