Accordion Solitaire

Accordion Solitaire turns a shuffled deck into a single row and asks you to compress it into one pile. The name fits: piles slide left as matches collapse, like folds in an accordion. The rules sound tiny, but the decision tree grows fast because each move changes future distances. You match by rank or suit, either one pile left or three piles left. It trains lookahead, restraint, and pattern memory. Deal the row and see how small you can make it.

1. Deal the deck face up into a row of piles, one card per pile.
2. Check each pile against the pile immediately to its left.
3. Also check each pile against the pile three spaces to its left.
4. If the top cards match by rank or suit, move the right pile onto the left pile.
5. Close the gap after every move so all piles slide together.
6. Win by reducing the whole row to one pile, or aim for the fewest piles possible.

• Accordion uses one standard 52-card deck.
• Only top cards determine whether piles match.
• A legal move matches either rank or suit.
• A pile can move one space left or three spaces left.
• Moves always go left, never right.
• The game ends when no legal move remains.

• Check three-left moves before one-left moves. Longer collapses often preserve more future matches.
• Keep useful suits alive. If many Hearts remain near each other, avoid burying the only Heart that links them.
• Watch rank clusters. Four Queens spread across the row can create multiple collapses if you delay the right one.
• Avoid automatic early moves. A legal match can still damage the row by breaking a stronger three-left setup.
• Scan from left to right after every collapse. Distances change, so a new three-left move may appear immediately.

• One-Handed Solitaire: A related row-compression game often played by holding a small packet in one hand.
• Royal Marriage: Another non-builder patience game that uses a row of cards and targeted eliminations.
• Golf Solitaire: A faster rank-sequence game for players who like compact card puzzles.

• The whole game uses a single row, so the board is easy to read.
• Tiny rules create deep planning choices.
• Reducing the row from 52 piles to a handful feels rewarding.
• The game works well as a quiet logic exercise.
