Complete guide
Catherine the Great is a complete browser implementation with its own versioned rules profile. Build seven suited Queen-down arms around one heart King-up center while ten ascending rank piles refill automatically.
Seven foundations are seeded with assigned Queens, the central foundation with the King of hearts, ten tableau piles receive one card each, one waste card is exposed, and eighty-five cards remain in stock.
Single cards build tableau upward by rank with Ace-King wrap, regardless of suit, and any card may enter an empty pile. Tableau or waste cards feed the seven assigned suited foundations downward from Queen and the heart center upward from King. An emptied tableau pile immediately fills from waste, drawing a stock card first when needed.
Complete all eight thirteen-card foundations and place both decks in Catherine's seven arms and central heart sequence. Coordinate the seven descending arms with the wrapped heart center, then use forced refills to expose the final suited cards in foundation order.
Clear tableau piles when the waste refill is useful, and balance the duplicate Queen arms so one copy of a suit does not monopolize every accessible descending rank. Tableau builds upward while most foundations build downward, and an empty tableau consumes the waste automatically instead of remaining as workspace.
