What Cards Can an Ace Be Placed On in Spider Solitaire?
An Ace may go on any Two, regardless of suit, or into an empty column. It cannot go on a Three, and no lower card can be placed on the Ace.
An Ace may go on any Two, regardless of suit, or into an empty column. It cannot go on a Three, and no lower card can be placed on the Ace. Spider uses one rule for placing on a destination and a stricter rule for moving a group. Keeping those two tests separate resolves most apparent contradictions.
Worked position
- Legal: A♠ → 2♥; A♠ → empty column
- Illegal: A♠ → 3♥
A♠ may be placed on 2♥ because the destination is exactly one rank higher, and it may also move into an empty column. An Ace is the lowest endpoint of a descending Spider build. It can be placed on a Two or in a space, but it cannot receive another lower card.
It cannot go on 3♥ because that skips a rank. Verify legality in three layers: the source card or tail must be available, the moving cards must be ordered correctly, and the leading card must satisfy the destination rule.
A second position
- Destination: 4♦
- Sequence: 3♠–2♠–A♠
- Legal: yes
The suited group 3♠–2♠–A♠ can move onto 4♦ as one unit even though the destination suit differs. For a Spider group, every selected card must be contiguous, descending by one and in the same suit. A suit break below or inside the selection divides the stack into separate movable units.
Ace is the bottom of a descending run and cannot receive another lower card. Access, not visibility, is the key resource. A card matters when it becomes selectable and already has a legal destination; merely seeing it under another card does not improve the position.
When to change the plan
If the selected cards fail the same-suit, contiguity or destination-rank test, shorten the move to a legal tail or choose another destination. After moving A♠ / 2♥ / 3♥ / 3♠, count the suit breaks that remain.
Common mistake
Do not confuse a legal single-card placement with a legal group move. The cards around A♠ / 2♥ / 3♥ / 3♠ must pass both tests separately.
Practical check
- Is every selected card contiguous and in the same suit?
- Does the leading card fit a destination exactly one rank higher?
- If the destination is empty, have you kept the group rule separate from the rank rule?
- What suit break will remain after the move?
The rule applies in Spider 1 Suit, Spider 2 Suits and Spider 4 Suits. Suit count changes difficulty, not this move test. Re-evaluate the dependency around A♠ / 2♥ / 3♥ / 3♠ after every removal, return or newly exposed card.
