Walkthrough for 14: turn it so yellow is facing you, black top & purple on bottom. Pull yellow left. Slide the grey onto the yellow, then pull it along the yellow to the right. Pull the black along the yellow towards the grey to the right. Pull the purple towards you. Pull the yellow towards you, then slide it off to the right until it vanishes. Pull the grey out until it vanishes. The other 4 disconnect easily... you're done!
