Complete guide
Contradance uses the independently implemented Contradance PySolFC 3.6.1 fixed rules v1 profile (R580). Contradance is defined by one exact interaction: Two groups of foundations split the deck into descending Five-through-A-then-K sequences and ascending Six-through-Queen sequences.
Read the opening of Contradance by locating every lane, clue, reserve, room, or fixed element named in its rule. Two groups of foundations split the deck into descending Five-through-A-then-K sequences and ascending Six-through-Queen sequences. The seeded deal and rules version reproduce that public starting information without exposing a hidden completion.
Check each proposed action against the current position and this boundary: Two groups of foundations split the deck into descending Five-through-A-then-K sequences and ascending Six-through-Queen sequences. Illegal, stale, and post-finish actions are rejected without changing the board.
Finish Contradance when both opposed foundation groups complete their prescribed lower and upper rank streams. Completion is checked from the entire position, not from a displayed answer or a visual approximation. During the final few decisions, compare every unresolved obligation with the target: both opposed foundation groups complete their prescribed lower and upper rank streams. Keep the option described in the strategy note available until the last forced dependency is settled.
Separate the lower descending stream from the upper ascending stream early, and preserve access to the Five/Ace/King transition cards that close each half. Building only the visibly active half can bury a rank needed by the opposite bank, leaving neither the lower nor upper foundation stream able to advance.
Separate the lower descending stream from the upper ascending stream early, and preserve access to the Five/Ace/King transition cards that close each half. This matters specifically because two groups of foundations split the deck into descending Five-through-A-then-K sequences and ascending Six-through-Queen sequences.
Building only the visibly active half can bury a rank needed by the opposite bank, leaving neither the lower nor upper foundation stream able to advance. Recheck the legal boundary before choosing a replacement move.
Contradance is complete once both opposed foundation groups complete their prescribed lower and upper rank streams. The terminal check examines every relevant pile, cell, edge, room, and clue before awarding the result. Undo and redo expose alternative branches without revealing an authored answer.
