Will o' the Wisp is played similar to Spiderette.
Player is first dealt 21 cards into seven piles, 3 cards in each pile.
The top card on each pile is turned face up, so that there are 7 face-up cards.
The remaining cards are set aside, forming a draw pile.
Cards in the tableau are built down regardless of suit.
Only the top cards of each column can be moved; however, a sequence of cards that are in suit can be moved as one unit.
Face-down cards that become exposed are turned face-up and empty column spaces on the tableau are filled by any card. If all possible plays have been made, a new set of seven cards (one for each column) are dealt from draw pile. After four such deals, the three left over cards are dealt on the first three columns.
Once a suit sequence of thirteen cards from king down to ace is successfully built, it is discarded from the game.
The game is won when four such suit sequences are built and discarded this way.
