Step 3: Choose your timings
You can then choose how frequently you’d like your slides to move on, ranging from once a second to once a minute.
The autoplay dropdown menu is visible. There are several options including: Every 2 seconds, every 3 seconds, every 5 seconds, every 10 seconds - up to Every minute.
You can also choose to play them on a loop, which is handy if you want to play something like a photo presentation in the background during an event.
The same screenshot as the previous image. Beneath the 'Every X seconds' options is an option to Loop the slides. This is highlighted.
Once you’ve chosen the timing settings you want, click Play at the top of the pop-up menu.

Embedding a timer on screen in Google Slides
If you want to add a visible countdown timer to your slide to give your audience a set period of time for a break or a group activity, the easiest way to do this (at the time of writing) is to head over to YouTube and search for a timer video (yes, these are a thing!).
Step 1: Search for a timer video on Youtube
You can do this without leaving Google Slides. To start, go to Insert in the toolbar and then select Video.
Screenshot of Google Slides showing the Insert Video pop up. The search tab is selected and the YouTube Search bar is on the screen. In the search bar is the text "2 minute timer"
A pop-up will appear that allows you to search YouTube. Type the length of timer you want into the search bar and click the blue Search button. A range of options will pop up. You can choose from different backgrounds and even different music options, but for the purposes of this tutorial I’m going to choose a two-minute timer with a plain black background.
