How to play
Complete Accordion's Revenge when all cards have been removed through the game's exact exposed-card predicate. The runtime checks the entire position rather than a visual approximation or an unsupported solvability claim.
- Accordion's Revenge 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 a card may combine with a matching-rank or matching-suit card exactly one or three positions away, continually shortening the accordion row. Invalid, stale, non-finite and post-terminal actions leave the state and undo history unchanged.

Strategy tips
- Start Accordion's Revenge with the most constrained exposed obligation, then preserve a second legal route before committing the first. A card may combine with a matching-rank or matching-suit card exactly one or three positions away, continually shortening the accordion row.
- Do not treat a locally tidy move as proof of progress in Accordion's Revenge; it can consume the only route that still satisfies the full boundary rule.
- Near the end of Accordion's Revenge, count every unresolved destination or constraint before committing a narrow move. Use undo to compare legal branches, then recheck that all cards have been removed through the game's exact exposed-card predicate.
