The Scots first unfolded an almost perfect score under the boot and mischief of Russell, his inspired N.10, in the oven and at the mill to find perfect touches, succeed in his kicks and serve his partners.
They led 20-0 at the break, then 27-0 in the 44th minute following Duhan van der Merwe's second try of the evening.
But the Welsh rebelled in the second half, inflicting a scathing 26-0 on the Scots who had become feverish as the match progressed.
Wales consoles itself for this tiny defeat with the point of the offensive bonus (with four tries) and that of the defensive bonus.
