Accordion Solitaire

Accordion Solitaire is deceptively simple in concept but brutally difficult in execution. All 52 cards are dealt in a row. Compress piles by matching suit or rank with the pile one or three positions to the left. The goal is to compress all cards into a single pile — but with a win rate under 1%, Accordion is one of the hardest solitaire games ever devised. Most games end with 5-15 remaining piles.

How to Play Accordion Solitaire

Layout

All 52 cards are dealt face-up in a single row (or wrapped grid), one card per pile.

Objective

Compress all 52 cards into a single pile by matching cards.

Step-by-Step Instructions

A card can be moved onto the card 1 position to its left, or 3 positions to its left.
A move is valid if the two cards share the same suit OR the same rank.
When a card is moved, the pile it came from disappears and all piles to the right shift left to fill the gap.
After each move, scan the row again — new matches may have appeared.
Work from left to right, but prioritize 3-position matches as they compress more piles.
Win when all cards are compressed into a single pile (very difficult — win rate is under 1%).

Accordion Tips and Strategies

Prefer 3-position matches over 1-position matches — they compress more efficiently. Scan the entire row before each move; the obvious match isn't always the best one. Look for chain reactions where one compression sets up another. Patience and careful analysis are essential; random play almost never wins.

Accordion Solitaire Rules

Accordion Solitaire Rules: Deal cards one at a time from the deck into a row. After dealing each card, check if it can be moved. A card can be moved onto another card if they match in rank or suit AND the target card is either one position to the left or three positions to the left. When you move a card, all cards to its right shift left. Continue dealing and moving until the deck is exhausted. Gameplay: The goal is to compress all 52 cards into a single pile. This is extremely rare - most games end with multiple piles. There are no redeals or second chances. Strategy: When you have a choice between moving one space or three spaces, the decision significantly affects the outcome. Most games are likely unwinnable, but the quick gameplay makes trying again appealing. Winning a game of Accordion is considered a major achievement.

Scoring System

Accordion Solitaire is typically scored by counting how few piles remain. The goal is to compress all 52 cards into a single pile. Each successful merge moves you closer to a perfect game. Some scoring systems award points for each merge completed.

Common Mistakes to Avoid

Accordion players often make the first available merge without looking ahead. Check if a merge now blocks a better merge later. Position matters — merging toward the left compresses the row faster but may strand useful cards.

Accordion Solitaire — Frequently Asked Questions

Everything you need to know about Accordion Solitaire.

What is Accordion Solitaire?

Accordion Solitaire is a challenging card game you can play for free online at Solitaire.fyi. No downloads or registration required — play instantly in your browser on any device.

What is the win rate in Accordion?

Accordion is one of the hardest solitaire games with an estimated win rate well under 1%. Some experts believe fewer than 1 in 100 deals are winnable. Most games end with 5-15 piles remaining.

When should you move one space vs three spaces?

This is the key strategic decision in Accordion. Generally, moving three spaces creates more opportunities to collapse the layout, but sometimes one space moves are necessary. There is no definitive strategy - much depends on the deal.

What is the win rate for Accordion Solitaire?

Accordion has one of the lowest win rates of any solitaire game — under 1%. Compressing all 52 cards into a single pile is extraordinarily difficult. Most games end with 5-15 remaining piles even with strong play.

Should I prioritise 1-position or 3-position matches?

Generally prioritise 3-position matches as they compress more cards at once. However, always check if a 1-position match now would set up better 3-position matches later. Think several moves ahead before committing.

How does Accordion Solitaire work?

Cards are dealt face-up one at a time into a single row. A pile may be moved onto an adjacent pile (1 position away) or onto a pile 3 positions to the left, but only if the top cards share a suit or rank. The goal is to compress all 52 cards into a single pile.

Why is Accordion so hard to win?

The compression rules are extremely restrictive — most deals contain "dead" arrangements where no further compression is possible. Even with perfect lookahead, the deal itself decides whether a single-pile finish is achievable. Treat each completed compression as a small win.

What is the difference between Accordion Classic and Accordion Easy?

Classic uses the strict original rules (suit or rank match at exactly 1 or 3 positions). Easy variants relax this — for example, allowing matches at additional distances or accepting any rank within 1 of the target. Easy variants push the win rate from <1% to roughly 5-10%.

Why is Accordion so hard?

The combination of a single-row layout, limited matching rules (suit or rank at distances 1 or 3), and the requirement to reach a single pile creates an exponentially constrained puzzle. Even with perfect analysis, most deals have no solution.

Is Accordion Solitaire free to play?

Yes — 100% free at Solitaire.fyi with no hidden costs, no sign-up, and no ads that interrupt gameplay. Play unlimited games on desktop, tablet, or mobile.

What is a good win rate for Accordion Solitaire?

Win rates vary by variant and skill level. This is a challenging variant — even experienced players may only win 10-30% of games.

History of Accordion Solitaire

Accordion Solitaire, also known as Idle Aces or Methuselah, is one of the oldest known patience games. The name "Methuselah" refers to the biblical figure who lived 969 years — a nod to how long the game can take. Its extreme difficulty (under 1% win rate) makes it a patience-testing marathon. Despite its simplicity — just matching by suit or rank — the game has fascinated card players since at least the mid-19th century.

Cognitive Benefits of Accordion

Accordion Solitaire exercises broad-field visual scanning and pattern recognition. Searching for suit or rank matches at distances of 1 and 3 across a long row trains systematic visual processing. The extreme difficulty also builds persistence and analytical resilience.
