Everyone plays at once. Hold two cards to turn them over, work out what you see, and mark it on the card.
These are Windows gestures, not the Deck, so they have to be switched off once on this laptop. All three live in Settings › Bluetooth & devices › Touch.
Then tap Full screen, so there is no browser or taskbar left at the edges.
Hold Ctrl (or Alt) and press on a card: a fake cupped hand of 5 contacts peeks it.
Shift + click a card to pin a fake finger there, then click a second card to claim the pair.
On Windows, turn off Settings › Bluetooth & devices › Touch › "Three- and four-finger touch gestures", or Windows may grab the cupped hand.
