Things sadly didn’t get off to a great start for Riddoch despite her joy at drawing Scotland as Steve Clarke’s side suffered a 5-1 defeat to Germany.
Cumming however couldn’t have asked for a better start from Switzerland, who secured a 3-1 victory over Hungary.
Actor and Yes supporter Cumming is playing for Scottish Trans while Riddoch is hoping Scotland can go all the way to win some money for Front Lounge Dundee.
The match will kick off at 8pm and will be broadcast on the BBC.
Elsewhere, Scottish comedian Mark Nelson told The National he was happy with drawing Germany so long as they made a mess of their first game.
Unfortunately, that wasn’t the case although a victory over former SNP MP Angus MacNeil (above), who has drawn Hungary, would make it two wins from two for the comic.
MacNeil is playing for the Bethesda Hospice Stornoway while Nelson is hoping Germany can put home advantage to their use to lift the Euros and win £1000 for Marie Curie Cancer.
Germany vs Hungary is set to start at 5pm and will also be shown on the BBC.
Scottish screenwriter Lesley Paterson and comedian Janey Godley (below) meanwhile will each be hoping to pick up their first win of the tournament.
Godley has drawn Albania who put up a fight against Italy after taking an early 1-0 lead.
It wasn’t to be though as the holders turned things around quickly, leading 2-1 by the 16th minute and holding out for the win.
Paterson meanwhile has drawn Croatia, who struggled in their opener with a 3-0 loss to Spain.
Godley is playing for Baby Loss Retreat while Paterson picked Pancreatic Research Fund as her chosen charity.
The match will kick off at 2pm and be available to view on STV.
