The series focuses primarily on playing cards, but has also included board games, puzzles, dice, and dominos.

Early titles had a volume numbering and included humorous computer opponents drawn from other Sierra video game series.

The games included are: Crazy Eights, Old Maid, Hearts, Gin Rummy, Cribbage, and Klondike.

For example, Leisure Suit Larry begins to comment about women, while Roger Wilco wants to escape the game to save the universe again.

SCI was originally created to aid in the development of Sierra's core line of adventure games.

Working with SCI to implement card games and to code artificial intelligence for the characters proved challenging.

The 28 solitaire games offered are: Calculation, Strategy, Eagle Wing, Beleaguered Castle, Klondike, Canfield, Golf, Flower Garden, Scorpion, Spiderette, La Belle Lucie, Fortress, Baker's Dozen, Bristol, Eight Off, Shamrocks, Yukon, Eliminator, Slide, Bowling, Nestor, Aces Up, Gaps, Penguin, Pyramid, Triplets, and Poker Square.

Each character has five unique expressions in full speech (ranging from dislike at the plays, happiness, or praise).

Computer Gaming World stated that interacting with Sierra characters in Volume 1 such as Leisure Suit Larry and Princess Rosella was fun, but annoying for those who preferred cards to humor.
