We re-created Tetris™ in ClojureScript. We mainly did this to produce the pleasure and to celebrate the 30th anniversary of its original release in 1984. Our remake enabled us to host a small, local tournament to share a montage of the game's history. Choose from 10 themes representing the popular versions from its past.

In the beginning, we worked on the game at least once a week. It got pretty crazy at the end closer to deadline, but our initial process is documented in blogs below:

• DevBlog 1 - data, collision, rotation, drawing
• DevBlog 2 - basic piece control
• DevBlog 3 - gravity, stack, collapse, hard-drop
• DevBlog 4 - ghost piece, flash before collapse
• DevBlog 5 - game over animation, score
• DevBlog 6 - level speeds, fluid drop, improve collapse animation, etc.
• DevBlog 7 - draw next piece, tilemap for themes
• DevBlog 8 - allow connected tiles for richer graphics
• Day 9 - live board broadcasting (no blog)
• Day 10 - chat room, more tilemaps, page layouts (no blog)
• Day 11 - page routing, username (no blog)
• Day N - socket netcode, spectate mode, MC controls, key-repeat control, chatroom, authentic theming, history graphs, ...

In the end, we wrapped up what we learned into an educational resource:

• Interactive Guide to Tetris in ClojureScript (below on the left)
• A minimal version intended for readability (below on the right)

1. Install Leiningen and Node.js.

2. Run the following in the project directory

   # install node.js dependencies
   npm install
   
   # install grunt
   npm install -g grunt-cli
   
   # compile LESS file
   grunt
   
   # compile ClojureScript files (this may take a minute)
   lein clean && lein cljsbuild once
   
   # copy the example config file (edit as needed)
   cp example.config.json config.json
   
   # start the node.js server
   node server.js

3. Open http://localhost:1984 in your browser.

If you want a REPL connected to the browser for interactive testing:

lein repl
