Monte Carlo Solitaire

Monte Carlo Solitaire, sometimes referred to as Weddings or Good Neighbors, is a classic matching game that stands out from the traditional building sequences found in Klondike or Spider Solitaire. Instead of stacking cards by suit or rank, your goal is to pair them up and clear the board.

Historically, this game became popular because of its fast pace and the visual satisfaction of seeing the grid collapse and refill. It relies heavily on your observation skills and your ability to plan several moves ahead to ensure no cards are left stranded.

Game Setup

To start a game of Monte Carlo Solitaire, a standard 52-card deck is used. After a thorough shuffle, the cards are dealt face-up into a 5x5 grid, totaling 25 cards. The remaining 27 cards form the stock pile, which will be used to refill the grid as you progress. Unlike Canfield or other complex patience games, the layout here is simple and entirely visible from the start.

How to Play

The objective is to remove all cards from the deck by matching pairs of the same rank (for example, two Jacks or two fives).

• Matching: You can only remove a pair if the two cards are adjacent to each other. Adjacency includes horizontal, vertical, and diagonal positions.
• Consolidating the Grid: Once you have removed all possible pairs from the current 5x5 layout, you trigger a "redeal" or "consolidation" phase. All remaining cards on the grid slide to the left and upwards to fill the gaps created by the removed pairs, maintaining their relative order.
• Refilling: After the cards have shifted, new cards are dealt from the stock pile into the empty spaces at the bottom right of the grid to restore it to a 5x5 layout.
• Winning: The game is won if you successfully pair and remove every single card from both the grid and the stock pile. The game ends if no more pairs can be made and the stock is exhausted or the grid is stuck.

Strategies and Tips to Win

While Monte Carlo Solitaire involves a fair amount of luck regarding the deal, these tips can help improve your success rate:

• Plan Your Pairings: Before clicking on the first pair you see, scan the entire grid. Sometimes, removing a specific pair will bring two other cards of the same rank together after the grid consolidates.
• Watch the Stock: Remember that you have a limited number of cards in the stock. If you are playing a version like Aces Up where every move counts, you know that efficiency is key.
• Prioritize Interior Cards: Cards in the center of the 5x5 grid have more neighbors (up to eight) than cards on the edges or corners. Removing central cards often opens up more possibilities for subsequent moves.
• Visualize the Shift: Try to anticipate where cards will land after the "fill the gaps" phase. If you have two cards of the same rank that aren't touching now, they might become neighbors once the cards above or to the left of them are removed.
