How to Play Calculation Expert Solitaire
Layout
Four foundation piles start with Ace, 2, 3, and 4. The remaining 48 cards form the stock pile. Four empty waste piles sit below.
Objective
Build all four foundations to King, each following a different counting sequence.
Step-by-Step Instructions
- Foundation 1 (Ace): builds by 1s → A, 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K.
- Foundation 2 (Two): builds by 2s → 2, 4, 6, 8, 10, Q, A, 3, 5, 7, 9, J, K.
- Foundation 3 (Three): builds by 3s → 3, 6, 9, Q, 2, 5, 8, J, A, 4, 7, 10, K.
- Foundation 4 (Four): builds by 4s → 4, 8, Q, 3, 7, J, 2, 6, 10, A, 5, 9, K.
- Draw one card at a time from the stock. Place it on a foundation if it's the next card in that foundation's sequence, or on one of the 4 waste piles.
- You can play the top card of any waste pile to a foundation. Plan waste pile placement carefully — a buried card can't be retrieved.
- Win when all four foundations reach King.

Calculation Expert Tips and Strategies
Expert rules demand flawless waste pile organization from the very first card. Pre-plan your pile assignments before playing: which foundations will each pile primarily serve? Mistakes compound quickly in this mode — a single misplaced card can cascade into an unwinnable position.
Calculation Expert Solitaire Rules
Scoring System
Calculation Solitaire scores 10 points for each card placed on a foundation. The four foundations follow different counting sequences (by 1s, 2s, 3s, and 4s), all ending at King. Strategic waste pile management is key — each card placed from a waste pile to a foundation scores the same. A perfect game scores 480 points (48 non-starter cards × 10).
Common Mistakes to Avoid
The most common Calculation mistake is poor waste pile management. Many players dump cards randomly onto waste piles, burying needed cards. Dedicate one waste pile to "late game" cards and keep frequently-needed ranks accessible on top. Forgetting which sequence each foundation follows (by 1s, 2s, 3s, 4s) leads to missed placements.

History of Calculation Expert Solitaire
Calculation Solitaire is one of the few patience games where nearly every deal is winnable with perfect play. First documented in the late 19th century, it was designed as a mathematical puzzle rather than a game of chance. The unique counting sequences (by 1s, 2s, 3s, and 4s) make it a favourite among players who enjoy arithmetic challenges. Albert Morehead and Geoffrey Mott-Smith, authors of the definitive "Complete Book of Patience" (1949), ranked it among the most skill-intensive solitaire games.
Cognitive Benefits of Calculation Expert
Calculation Solitaire trains mathematical pattern recognition and memory. Tracking four different counting sequences simultaneously exercises divided attention and numerical fluency. Waste pile management builds organizational thinking skills that transfer to real-world task prioritization.
