A quick-and-dirty Tetris clone written in a day to learn LiveScript, a fork of CoffeeScript.

Play it on my portfolio site.

• Super short — only 142 lines!

• Object-oriented
• Fully-featured (you can't technically win or lose; restarting consists of reloading the page)
• Super clean (adding the prediction took some hacks; OOP would be the right way to go)

Because this is in LiveScript, it must be compiled to JavaScript. I use rails, so here are rails-specific instructions.

Add tetris.ls to your app/assets/javascripts folder.

Add this to your Gemfile:

gem 'livescript-rails'

Add this to any HTML page:

<div class="tetris">
  <canvas width="200" height="360"></canvas>
</div>
