Can a Card Move from One Klondike Foundation to Another?

No. A card cannot transfer directly from one Klondike foundation to another. Each foundation is an independent, single-suit sequence that begins with an Ace and rises to the King.

If the heart foundation ends at 5♥ and the diamond foundation ends at 4♦, 5♥ cannot move onto 4♦. The ranks appear consecutive, but the suits differ. Foundation placement never uses the tableau’s red-and-black rule.

Why there is no valid target pile

The Ace that starts a foundation fixes its suit. A♣ creates the club foundation, so only 2♣, 3♣, 4♣ and the remaining clubs may follow. No spade, heart or diamond card can enter that pile.

Moving 5♥ to another pile would also leave a gap in the heart sequence. Klondike does not merge or redistribute foundations during play.

What you can do instead

Under PlaySoli’s rules, the top foundation card can return to a legal tableau destination. For example, 6♠ may return onto 7♥. After it has served as a tableau parent, it can move back onto 5♠ in the spade foundation.

That route is foundation → tableau → the same foundation, not foundation → foundation. Cards buried below the top of a foundation remain inaccessible.

A common visual confusion

The four foundation positions may look interchangeable while they are empty. Once an Ace is placed, the pile’s identity is determined by that Ace. Interfaces may also arrange piles in different suit orders, but the screen position does not change the rule.

Verify a disputed move

1. Name the suit of the moving card.
2. Check the Ace at the bottom of the proposed foundation.
3. Require the immediately lower card of the same suit.
4. If the move fails, test whether the top card can legally return to the tableau instead.

You can verify the behavior in Play Klondike Draw 1 and Play Klondike Draw 3.
