How To Create Memory Game in Python Using Tkinter
In this Python Tutorial we will see How to Create a Memory Game (card-matching game) with smooth animations, multiple difficulty levels, and a dark theme interface.
The Game Features:
- Multiple Difficulty Levels: 4x4 (16 cards, 8 pairs), 4x5 (20 cards, 10 pairs), and 5x6 grid sizes (30 cards, 15 pairs).
- Card Matching: Automatic pair detection.
- Move counter and timer: The game tracks moves, elapsed time, and provides detailed performance statistics.
What We Are Gonna Use In This Project:
- Python Programming Language.- VS Editor.

Project Source Code:
- Create frame for cards.
def create_game_grid(self):
# Create frame to hold all cards
self.cards_frame = tk.Frame(self.game_frame, bg=self.colors['bg'])
# Center the grid in the game area
self.cards_frame.pack(expand=True)
# Initialize cards list and get symbol pairs
self.cards = [] # Empty list to store card widgets
# Get grid dimensions for current difficulty
rows, cols = self.difficulty_levels[self.current_difficulty]["grid"]
# Double the symbols list for pairs
symbols = self.difficulty_levels[self.current_difficulty]["symbols"] * 2
# Randomly shuffle symbols to place them on the grid
random.shuffle(symbols)
# Store shuffled symbols for later reference
self.symbols = symbols
# Create cards in grid
for i in range(rows): # Loop through each row
for j in range(cols): # Loop through each column in current row
card_idx = i*cols+j # Calculate linear index from row and column
# Create card canvas
# Create canvas with fixed size And Set background And remove border
card = tk.Canvas(self.cards_frame, width=80, height=100,
bg=self.colors['card_bg'], highlightthickness=0)
# Position card in grid with spacing
card.grid(row=i, column=j, padx=5, pady=5)
# Bind click event
card.bind("<Button-1>", lambda e, idx=card_idx: self.on_card_click(idx))
# Create card back (visible initially)
# Create card shape And Add colored border
card.create_rectangle(5, 5, 75, 95, fill=self.colors['card_bg'],

# Add question mark and Set text color

# Create card front (hidden initially)
# Create card shape
# Add colored border
# Hide initially and add tag for later reference

# Use bold font for symbol
# Set text color
# Hide initially and add tag

- Method to check for a match between flipped cards.
