Can you move more than one card at a time?

In Klondike, any face-up sequence built down in alternating colors moves together, so a red six on a black seven travels as a pair. Yukon goes further: you can lift a group even when the cards beneath the top card are not in sequence, which makes for wildly different play. The receiving column still has to accept the bottom card of the group legally.

FreeCell only ever moves one card at a time in strict rules, but the interface lets you move a group as a shortcut for a series of single moves. The maximum group size equals (free cells + 1), doubled for each empty column. So the more open cells and columns you keep, the larger the runs you can shuffle around in one gesture.

Spider lets you move a run only if it's in the same suit and in descending order. A mixed-suit sequence won't lift as a group, which is exactly what makes higher suit counts so demanding. Knowing each game's grouping rule is half of playing it well.
