Preview

The game consists of:

• A controllable snake
• Randomly generated apples
• Score display
• Win and game-over screens
• Keyboard controls via arrow keys or WASD

---

Technologies

• Python 3
• Tkinter (GUI)
• Random
• OS module

Game Mechanics

• The snake continuously moves across the game field.

• When collecting an apple:

  • the snake grows,
  • the score increases,
  • a new apple appears randomly.

• The game ends when:

  • colliding with the wall,
  • colliding with its own body.

• The player wins at 30 points.

---

Screen Resolution

The game is currently optimized for:

• 2560×1440 with 225% scaling

Alternative values for 1920×1080 are already included in the code and can be enabled.

---

Customization Options

The following values can easily be changed in the code:

SPEED = 100
SPACE_SIZE = 100
BODY_PARTS = 3

Change Colors

SNAKE_COLOUR = "#00FF00"
FOOD_COLOUR = "#FF0000"
BACKGROUND_COLOUR = "#000000"

---

Game Field Size

GAME_WIDTH = 1137 * 2
GAME_HEIGHT = 640 * 2

Speed

SPEED = 100

The higher the value, the slower the game runs.

---

Zoom / Grid Size

SPACE_SIZE = 50 * 2

---

Features

• GUI with Tkinter
• Score system
• Random food generation
• Win condition
• Game-over screen
