What the 75,000-Deal Study Changes
The site tested 25,000 seeded opening deals in each standard Spider mode in June 2026. The data found that 1-suit, 2-suit, and 4-suit starts all averaged about 6.4 legal top-card moves, but same-suit top-card moves fell from 6.46 in 1 suit to 3.20 in 2 suits and 1.61 in 4 suits. That is why these tips focus less on making any legal move and more on preserving movable same-suit structure.
- Method: 75,000 seeded Spider Solitaire opening deals using the live deck model.
- Measured variables: legal top-card moves, same-suit mobility, zero-move starts, visible ranks and suits, and first-stock-row potential.
- Practical takeaway: reveal cards and create empty columns, but do not waste same-suit mobility for a cosmetic tableau.
- Limit: the study measured opening-board conditions, not full-game win rates or player outcomes.
