Variant on Black Widow and Spider Solitaire. Clear all cards from the game by grouping all cards in sets of 13 in suit and in sequence from King to Ace.
Groups of cards in the correct order (independent of suit) can be moved as 1 unit. You can only move a card or a sequence on a card in another column if that is 1 higher in sequence (independent of suit). You can also move a card (or sequence) to an empty spot. Click on the closed deck (top left) to deal new cards.
