DasTetris

A desktop Tetris game where the set of pieces, their colors, the unlock score for each piece, the field width, block size, colors and keys are described in JSON files – so the game can be extended with new shapes without touching the code.

📃 Features

Gameplay – falling pieces, rotation, line clearing, score and lines counter, next-piece preview
Progressive pieces – 23 shapes, new ones unlock as the score grows
Configuration – keys, colors, field width, block size and speed mode in JSON
Pause, restart and exit confirmation dialog (mouse or Y/N keys)

⭐ Advantages

Data-driven shapes – any new piece is a few lines of JSON: name, color, minimal score and a list of rotations.
Safe defaults – committed *_000.json defaults are used automatically when local configs are absent.
Runs from anywhere – configs are resolved next to the script or the built executable, not the current directory.
Clear config errors – broken JSON or a missing key stops the game with a message naming the file and key.

📌 Using

Gameplay

Standard Tetris rules on a 20-row field

← / → – move, ↑ – rotate, ↓ – drop one row
P – pause, R – restart, Esc – exit (with confirmation)
Score for cleared lines at once: 1 – 100, 2 – 300, 3 – 500, 4 – 800
The next piece is always different from the current one

Progressive pieces

The higher the score, the more varied the pieces

8 base shapes (configs/blocks.json): Square, Line, Line3 and L from the start; J from 900, S from 1000, Z and T from 2500 points
15 additional shapes (configs/blocks_ADD.json, optional): Dot, U, Corner, X, P, F and others, unlocked from 3500 up to 30000 points
Above 5000, 10000 and 15000 points the falling speed changes

Configuration

All settings live in configs/

config.json – keys (pygame key names, e.g. K_LEFT), controls help text, colors, store_width (field width in blocks), block_size (pixels), high_score_inc_speed
high_score_inc_speed: false – the game speeds up as the score grows, true – it slows down
blocks.json / blocks_ADD.json – pieces: name, color [r, g, b], min_score, shapes (list of clockwise rotations, 0/1 matrices); at least one piece must have min_score 0
If a local file is missing, its *_000.json default is used

🚀 Running

Requirements: Python 3.12, pygame 2.6.

python3 -m venv .venv
.venv/bin/pip install -r requirements.txt
.venv/bin/python das_tetris_gui.py                  # start the game
.venv/bin/python -m unittest discover -s tests -v   # run tests
.venv/bin/pip install pyinstaller
.venv/bin/pyinstaller --onefile das_tetris_gui.py   # build a single executable into dist/

The executable reads configs from a configs/ folder located next to it.
