The Games Solve Different Problems
Klondike is built around moving cards to four suit foundations from Ace to King. Spider is built around organizing the tableau itself into eight complete same-suit sequences from King down to Ace, which clear automatically when completed.
- Klondike usually uses one 52-card deck; Spider uses two 52-card decks.
- Klondike starts with seven tableau columns; Spider starts with ten.
- Klondike builds alternating-color tableau columns; Spider focuses on descending tableau runs, with same-suit sequences being the most useful to move.
