Form four sets of cards of the same suit from King to Ace within the Columns.
Using one deck, each of seven Columns is dealt 4 cards - 3 face down and the last card face up.
Every click on the Stock will deal 1 card to each Column. Click on the Stock after no more moves are possible (or desirable) in the layout. All Columns must contain at least 1 card before you may deal cards from the Stock. There are no redeals.
Columns are built DOWN in ANY SUIT. However, you should prefer to build in the same suit since it makes it easier to move cards around and the goal is to build sets in the same suit.
Any number of face up cards may be moved to another Column provided that all cards being moved are sequential in rank, and that the move satisfies the build rule above. For example, a 8, 7, 6 of Spades may be moved to another Column with a 9, but the cards 8, 7, 6, Q would not be allowed.
Sequences may be split apart once formed. For example, in a sequence of 8, 7, 6 of Spades, the 7 and 6 may be split apart from the 8 in order to be played to another 8.
When a same suit sequence of King through Ace is formed within a Column, it is removed from the layout.
One point is scored for each card built within a Column starting with a King. For example, if a Column has a K, Q, and J of the same suit then three points are scored for that combination. A full set of King through Ace is 13 points.
A harder version of Will O' the Wisp is called Spiderette where the only difference is the number of cards dealt at the start.
