Tetris Python

A Tetris clone coded in Python, using the Pygame library.

Originally used for a programming project in A-level Computer Science.

How to run

First go to the src directory:

cd <path_to_tetris-python_directory>/src

Then execute the main.py file from the command-line or terminal:

python3 main.py

The Pygame library must be installed. Visit https://www.pygame.org/wiki/GettingStarted for details.

Game objective

Clear as many lines as possible in order to rack up a high score. The more lines cleared simultaneously, the greater the number of points scored.

The blocks will fall faster as the level increses. Avoid letting them stack up too high, which will cause the game to end.

Controls

• Left Arrow: Move left. Hold for quick movement.

• Right Arrow: Move right. Hold for quick movement.

• Down Arrow: Fast drop (while held down).

• X key: Rotate clockwise.

• Z key: Rotate anticlockwise.

• Escape key: Toggle pause. Alternatively, click the pause button.

Score system

The points for clearing lines depends on the current level and the number of lines being cleared:

points = level * base.

The base values for each line are as follows:

• 1 line = 40 points
• 2 lines = 100 points
• 3 lines = 300 points
• 4 lines = 1200 points

Also one point is given for every space fallen while fast dropping.
