Generally speaking, there’s no hard limit to the number of blocks a maze can have.
However, participants’ attention will significantly drop the longer the maze lasts. A very time-consuming maze may cause participants to disengage and abandon the test.
You should be particularly mindful of this when hiring participants from the Maze panel. In these cases, there are some limitations in place to ensure that testers are compensated fairly for their time.
Maze length limits on panel orders
Unmoderated Mazes
If you intend to use the Maze panel, mazes shouldn’t be longer than 45 minutes.
If your maze goes over this limit, you’ll see the following error when attempting to place a panel order:
Study length must be less than 45 minutesIf you see this warning, you won’t be able to place a panel order until you shorten the maze.
Moderated Mazes
If you intend to use the Maze panel, Interview sessions can go as long as 60 minutes. We do not recommend holding interview sessions longer than 60 minutes.
AI Moderated Mazes
If you intend to use the Maze panel for AI Moderated sessions, the session must be no longer than 30 minutes.
How do you estimate the length of a maze?
For unmoderated studies, Maze length is determined by counting all blocks within the maze, assuming that each block requires 1 minute to be completed. This calculation includes the Welcome and Thank You screens.
In cases involving conditional logic or exclusive variant comparison, the count is based on the longest possible combination of blocks.
Workarounds
If your maze is too long, before placing a panel order, you’ll need to shorten the maze. You can do this either by hiding blocks in the maze, or by splitting it into two shorter ones.
A) Hide blocks to reduce the length of the maze
You can shorten the maze by going back to the maze editor and hiding non-essential blocks.
B) Split maze into two shorter ones
If hiding blocks in the maze isn’t an option, you can also divide the maze into two separate ones.
To do so, duplicate the original maze. Then, make the necessary edits to create two shorter mazes.
