Using Siri to Flip a Coin (2023)

Voice assistants like Siri have revolutionized the way we interact with technology. Siri, Apple’s voice assistant, offers a range of capabilities, from sending messages to setting reminders. One fun feature is the ability to flip a virtual coin, a handy tool when you need to make a quick decision. This article dives into the mechanics of how to get Siri to flip a coin for you.


  1. Device Compatibility: You need an Apple device with Siri functionality. This can be an iPhone, iPad, iPod touch, Mac, Apple Watch, or HomePod.
  2. Software: Ensure your device is running the latest version of its operating system. Older versions might have limited Siri capabilities.
  3. Siri Activation: Siri should be set up and ready for use. If you haven’t done so, navigate to Settings > Siri & Search on iOS devices or System Preferences > Siri on macOS to set it up.

Step-by-step: Getting Siri to Flip a Coin

  1. Activate Siri:
    • iPhone, iPad, or iPod touch: Say “Hey Siri” or press and hold the Home button (or the side button on iPhones without a Home button).
    • Mac: If “Hey Siri” is enabled, use that. Otherwise, click on the Siri icon in the top right corner of the menu bar or use the designated keyboard shortcut.
    • Apple Watch: Raise your wrist and say “Hey Siri” or press and hold the Digital Crown.
    • HomePod: Simply say “Hey Siri”.
  2. Give the Command: Once Siri is listening, clearly state: “Flip a coin”. Siri will virtually ‘flip’ a coin and tell you whether the result is “heads” or “tails”.
  3. For Multiple Flips: If you want to flip the coin multiple times, specify the number in your command like, “Flip a coin five times”. Siri will then flip the virtual coin the specified number of times and tell you each result.

Under the Hood: How Does Siri’s Coin Flip Work?

While the outcome may seem random, Siri’s coin flip operates on pseudo-random number generation (PRNG) algorithms, like many other computerized random processes. Here’s a brief overview:

  1. PRNG Algorithm: At its core, Siri uses a PRNG to determine the outcome of the coin flip. While true randomness is difficult to achieve in a computational context, PRNG algorithms can produce sequences of numbers that approximate true randomness.
  2. Binary Outcome: The coin flip has two possible results: heads or tails. Thus, Siri’s PRNG will effectively generate a binary outcome, translating one value to “heads” and the other to “tails”.
  3. Quick and Efficient: The simplicity of the coin flip task means Siri can return a result almost instantly, making it feel as swift as flipping a real coin.
