Kansas Solitaire
This is Canfield with only three tableau columns. But the ability to build in mixed suit makes it easier to win. All four games are free-to-play, no in-app purchases.
CLASSIC - Tableau columns build down in mixed suits.
NAKED - The reserve pile is revealed.
1-CARD - One pass through the deck one card at-a-time.
FLEX - Empty tableau columns are not automatically filled.
