Backbone Solitaire

Two central reserve piles are blocked by one extra card. Remove that blocking card before either reserve can supply its exposed top card.

The backbone supports eight foundations

  • Eight tableau spaces start with one card each. Build down by suit, moving only individual exposed cards.
  • Any card can fill an empty tableau space. Cards cannot be parked back on the central reserve.
  • Build eight foundations from ace to king by suit. The draw-one stock allows two total passes.

Free the block without trapping it

Twenty cards are divided between the central piles; the blocking card sits below them. Find a legal home for it, then inspect both newly available reserve cards. Prefer a reserve move that releases another useful card over drawing immediately. Win by moving all 104 cards onto the foundations, including every central reserve card.
