The main variation in many solitary games is the presence of five different colours instead of red and black and five foundations replacing four.
In games like Klondike, where red and black play a part, a variation could be to deal an eight stack tableau, build on the five estates in ascending order and place talon cards of the same estate one above or below the face value of a descending stack on the tableau. The chances of getting out using these changes are fairly high.
In Little Spider the layout changes to fit five estates.
Cards are moved from the talons to foundation in ascending or descending order. Deal fresh cards to talons when all moves have been exhausted.
