Simple Addition or Totals is a family of patience or card solitaire games that share certain aims and procedures.[1][2]
Moyse counts the games of Elevens, Fifteens, Tens and Thirteens as part of the Simple Addition family.[1] Parlett adds Baroness, Block Eleven and Block Ten, Decade, Haden, Nines, Seven Up or Seventh Wonder, Pyramid or Pile of Twenty-Eight, Fourteens and Eighteens or Ferris Wheel, Grand Round or Wheel.[2]
Simple Addition sometimes also refers specifically to the game of Thirteens.[3]
