Smart Color Path

Drag the color circles and try to place them in the path.

Check the connections to see if two colors can be put side by side in the path.
The connections can be displayed as a list, or in the circle itself. 

Keep placing the circles until you complete the path. You may have to replace the circles several times until you find the only possible solution.

Three difficulty levels and unlimited number of games for you to play.
