The objective is to assemble 8 descending sequences of the same suit from King down to Ace within the tableau columns.
You can arrange cards in descending order regardless of suit (e.g., placing a 6 on any 7), but you can only move a group of cards together if they form a continuous sequence of the same suit.
When a column becomes completely empty, any face-up card or valid single-suit sequence can be moved into it to open up pathways.
When you run out of moves, click the Deal Stock pile to add one face-up card to every column. Note that all columns must contain at least one card before dealing.
Assembling a complete continuous run from King to Ace automatically clears those 13 cards into a completed vault slot.
