About

generic tetromino game is a public domain extensible clone of NES Tetris. The base game remains as faithful to the original NES Tetris as possible, but the game also adds new features and includes a modding API. Download

Features

end goal is to exactly replicate behavior of NES Tetris, down to the frame
replicates nearly all bugs in the original game, with options to fix them
nearly everything can be tweaked with mods: see the Lua API
support for saving and playing back game replays
leaderboard is saved to disk
speed is 60Hz by default, but is adjustable down to 10Hz and up to 480Hz
start at any level from 0 to 249
options are persistent and saved to disk
the lines per level can be set to "constant" to have every level last only 10 lines. Perfect for practicing transition!
custom RNG seed can be set for deterministic pieces
local and online multiplayer, with (optional) garbage piling
optional hard drop feature

Mods

Mods exist to implement different rotation styles (such as guideline rotation), lock delay, ghost piece, detailed in-game statistics (such as drought, Tetris rate, and DAS charge), and RNG algorithms (such as 7-bag).

Controls

The default controls use the keyboard. Arrow keys for up, down, left, and right; z and x for flip ccw and cw (respectively), and return for start. You probably want to remap these to something more comfortable (controllers are supported and very much recommended!)

I use the USB NES RetroPort v2 to connect an actual NES controller via USB (not sponsored, just happy with the purchase).

Future stuff

This project is still a work in progress. Here's some things that I'd like to add in the future:

Flesh out modding API, and move some built-in stuff to mods
More extensive tests showing that this actually does exactly replicate all behavior of the original, including super subtle stuff
