Number of Players:  Typically played by 2 players, but can be adjusted for more players (explained later).

Objective: Be the player who accumulates the most pairs of dominoes by correctly matching their pips (dots) after they are flipped face down.

Components:

• Double-six domino set (28 dominoes)
  

Setup:

1. Shuffle the Dominoes: Mix all the dominoes face down on the table.

2. Deal the Dominoes: Depending on the number of players:

   • 2 Players:  Flip all dominoes face down and arrange them in a rectangular grid (e.g., 4 rows of 7 dominoes). Leave some space between each domino for easy flipping.

   • More Players (Optional):  For more than 2 players, you can either:

     • Increase the number of dominoes used (if you have another set).

     • Deal a smaller hand to each player, keeping the remaining dominoes face down as a draw pile for when players make a match.
       

Gameplay:

Concentration is a turn-taking game that relies on memory and strategic flipping:

1. Turns: Players take turns in a clockwise direction.

2. Flipping Dominoes:

   • On your turn, you will flip over any two face-down dominoes from the grid (or draw pile if playing with more than 2 players).

   • The goal is to find two dominoes that have the same number of pips (a matching pair).

3. Matching Pairs:

   • If the two dominoes you flipped reveal a matching pair (same number of pips on both sides), you win the pair and keep them face up in front of you. You get another turn.

   • If the two dominoes you flipped don't match, simply flip them back face down in their original positions and the turn passes to the next player.

4. Remembering Positions:

• The key to winning Concentration is memorizing the positions of the dominoes you've already seen. This helps you choose dominoes that might be a potential match based on what you've previously flipped.

5. End of Game:

• The game ends when all the dominoes have been revealed in matching pairs.
  

Winning the Game:

• The player with the most number of matching pairs wins the game!
  

Variations:

• Time Limit:  For a faster-paced game, you can introduce a time limit for each turn (e.g., using a timer or hourglass).

• Points:  Instead of simply collecting pairs, you can assign points to different dominoes based on their value (e.g., higher double dominoes = more points). The player with the most points at the end wins.
  

Tips and Strategies:

• Pay Attention: Focus on the dominoes you flip, especially their positions on the grid. This will help you remember where potential matches might be.

• Strategic Flips:  As the game progresses, try to choose dominoes that are strategically located near previously flipped dominoes, increasing your chance of finding a match.

• Play with a Partner (More Players):  If playing with more than 2 players, consider playing in teams. This allows for communication and strategizing between teammates to remember domino placements.
