Joints

In this Android game, you must use your logic abilities to solve puzzles based on color changing. You must turn all red tops into green by tapping the joints of different figures marked by rings. You can paint several tops at once if they are connected with lines, so try to make as few moves as possible to get an extra reward. The game features minimalistic graphics, 144 hard levels, useful clues and bonuses, and a one-finger system of controls.
