# How does Groups work?

Groups allows you to group similar experiments together and publish them as one. Doing this allows a participant to choose the experiment they want to do from a selection of different options. 

For example, suppose a participant is doing a meditation experiment; they can choose meditation experiments of different durations**.** They won’t see the many experiments you’ve created in Builder combined to create one experiment they are seeing. They see one experiment with different options.

By grouping all of these individual experiments and tagging them with the different properties, the participant can select which experiment they want to do and is unaware of the various properties that make up the group.<br>
