The Terminal is an application inside all Macs that lets you access your computer’s command-line interface. It might be intimidating at first, because it's not as intuitive as the usual user interface, but it offers a lot of neat features, and you can use it do a lot of things that you would otherwise do manually on your system. This article will show you how to play old-school games in the Terminal. If you’re using a current version of macOS, you’ll probably need to install Emacs first.

Playing Games in Terminal

  • Before you can play games in Terminal, you’ll need to install Emacs. You can do this in Terminal if you have Homebrew installed.
  • To execute a game in Emacs, enter the command emacs -q --no-splash -f (name of game) .
  • Popular Emacs games include Tetris, Snake, and Gomoku.

  1. If you don’t see the
    Mac Terminal
    Terminal application in your Dock, click the
    Mac Spotlight
    Spotlight icon at the top right side of your screen and type in terminal . Click on the first search result to launch the app.
  2. Unless you’re using an old version of macOS, you probably don’t have Emacs installed on your computer. This is an application you’ll need to play old-school games in Terminal. In order to get Emacs, first you need to install Homebrew, a package manager that allows you to make special modifications to your Mac. [1] To install it:
    • First, install Apple’s Command Line toolkit if you haven’t already done so. In Terminal, enter the command xcode-select --install and press Return .
      • If a window pops up asking if you want to install the Command Line, click Install . Follow the prompts to finish the installation process.
      • You’ll see an error message if you’ve already installed the Command Line toolkit in the past.
    • If you’re using macOS Catalina or later, switch to the bash shell before you continue. To do this, enter chsh -s /bin/bash , type in your Mac’s administrator password, and then restart Terminal.
    • Enter the following command and then press Return : /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh )"
      • When prompted, enter your administrator password and press Return , then press Return again. Wait for the installation to complete.

  3. This will install Emacs on your Mac. This process may take several minutes. [2]
    • If you have an older Mac and you suspect you might have an outdated version of Emacs installed, run the following commands first to uninstall it: [3]
      • sudo rm /usr/bin/emacs
      • sudo rm -rf /usr/share/emacs
  4. Replace “(game)” with the name of the game you want to play (no parentheses). A new window will pop up with your game in it! [4]

  1. Press Return to run the game. A window should appear, and Tetris blocks will start falling.

Snake

  1. A window will appear with a yellow “snake” made of blocks moving around inside it.
  2. Try to collect the beads that appear on the screen.
    • The objective of Snake is to guide your snake around the screen, collecting beads as they appear. The more you eat, the more your score rises, but the snake also gets longer.
    • Hitting the side of the screen or hitting your tail will kill your snake, and you will lose.
    • Other commands include n (to start a new game), p (to pause your game), and q (to end the game).
    • It can be a little tricky to switch to the new window quickly enough to start playing before your snake hits a wall. You may need to press n to start a new game.

    • Gomoku is like Connect 4, only you need 5 in a row to win.

  1. A window should appear with two yellow paddles on each side and a red ball bouncing around.
  2. Move the paddle on the left with the left and right arrows or the 4 and 6 keys , and the one on the right with the up and down arrows . The score is under the playing screen.
    • You might need to maximize the window to see both paddles.
    • The objective of pong is to send the ball into the opponent's area. The only defense they have is the paddle, which is used to re-send the ball to you.
