About
Tetris is a puzzle video game created by Alexey Pajitnov in the mid-1980s, in which falling four-block tetrominoes are stacked and cleared by filling complete horizontal lines. Tetris-CSharp is a Tetris implementation built as a Windows Forms (WinForms) application, created to demonstrate that a WinForms-based Tetris game is feasible.
How it differs from the original
It supports custom blocksets — player-defined piece shapes stored in text files with a specific format — a customization option not present in the original game.
Getting started
Run the WinForms application on Windows; custom piece sets can be added by placing appropriately formatted blockset files in the same directory as the executable.
