A Guaranteed Winnable deal is more than a promising shuffle. Solitaire All Day stores a seed and a complete winning action sequence for each certified deal. Verification recreates the deal, applies every action through the public rules engine, and checks that the result is a legitimate win.
Choose a certified deal
Open the game, go to Settings and choose Guaranteed Winnable under New games. Choose Draw 1 or Draw 3, then start a New Game. The certificate must match that draw mode. Random remains a separate option.
The launch pool contains 1,000 verified Draw 1 deals. Daily uses a frozen reservation from that same pool; it does not invent an uncertified shuffle when a date opens. Certified Draw 3 deals are also available.
What the guarantee means
There is at least one winning route from the initial deal. It does not mean every choice you make will keep that route available, or that the solution is the shortest possible one. Undo and Restart let you explore another approach without changing the original deal.
If a certificate is missing or fails verification, the game does not label a random replacement as guaranteed.
Assistance without false certainty
Smart Hint uses a verified winning path when one is available. After you deviate, it can search the current position within a bounded budget. A limited search may return unknown; that does not mean the position is impossible. Auto Complete likewise needs a verified winning suffix and sends its actions through the normal game and Undo history.
