There were tries from George North and Jonathan Davies to savour for the 63,188 fans at Principality Stadium, with Davies announcing his return to the international arena after a year on the sidelines with injury with the best score of the game.
A set-piece move off a line-out 35 metres out saw Gareth Anscombe set his centre racing through a big hole after fending off opposite number Huw Jones. North brushed aside three defenders to bag his 34th try for Wales in the first half and could have had a second.
A foot in touch as he raced onto a great chip ahead by Anscombe 13 minutes into the first half ruled out what would have been the first try of the game. The Scots also had two second half tries ruled out by the TMO.
Giant lock Jonny Gray was spotted making a double movement as he drove for the line and then Peter Horne was spotted dropping a chip over the top of the Welsh defence by brother George nine minutes from time.
