After a long boring day at work, what about taking a short break and play some cool tetris game on your Mac terminal? Yes, you hear me right, I am referring to the black, ugly, unglamorous terminal app that you never want to open, and you can play tetris on it. Here’s how:

Open up your Finder and go to Application -> Utilities. Open the Terminal app.

Type emacs. You will see a lot of text. If you don’t understand, just ignore it.

Press the ‘escape’ button on your keyboard, follow by ‘X’.

Type ‘tetris’ (in lowercase and without the quote) and press ‘Enter’.

Use the arrow keys to move the block left/right and the arrow-up key to change shape. Space to drop the block.

Enjoy!
