How to play
Complete Twin Queens when all cards have reached foundations in the profile's required rank, suit, colour, direction, source and capacity order. The runtime checks the entire position rather than a visual approximation or an unsupported solvability claim.
- Twin Queens reconstructs its published opening from the route ID, rules version and local seed. Fixed clues, hidden cards and editable decisions remain separate, and restart reproduces the same position without a network request.
- A transfer is legal only under queen-led empty lanes and two downward foundation banks invert the usual ace-first plan; paired reserves expose one card per bank cycle. Invalid, stale, non-finite and post-terminal actions leave the state and undo history unchanged.

Strategy tips
- For Twin Queens, compare the immediate move with the next two forced obligations and keep the rarer destination available. Queen-led empty lanes and two downward foundation banks invert the usual Ace-first plan; paired reserves expose one card per bank cycle.
- Avoid importing a familiar rule from a related game into Twin Queens; this profile validates its own source, direction and terminal conditions.
- Near the end of Twin Queens, count every unresolved destination or constraint before committing a narrow move. Use undo to compare legal branches, then recheck that all cards have reached foundations in the profile's required rank, suit, colour, direction, source and capacity order.
