The last screen of a path shouldn't be reused on the same path or on another path in the same block.
When the last screen of a path is reused in a path, you'll get a message to remove the screen from the path or change your last screen:
This path cannot contain the end screen from another path. Please remove the highlighted screens from the path, or change the last screen.
The paths you set are used to measure the Direct and Indirect success metrics in Maze. Reusing the last screen would severely skew these metrics.
A mission is complete once a user reaches the last screen of a path. If the last screen is reused in any path, it would be considered an Indirect Success because the user reached the last screen even though they didn't arrive at the end of the path.
To break this down further: If your path is A → B → C, the mission will be complete once the user reaches C.
Now, if you would set the path as A → B → C → B, the mission will stop as soon as the tester reaches the first “B” screen.
As we can see here, testers would reach the end screen on the second step of this flow rather than the fourth and final step. This would mark the test as complete with an indirect success result because the tester reached the end screen but not by the set path.
You should make sure the last screen isn't included in any path. If you get an Invalid path message, here's what you should do:
- Remove the highlighted screens from the invalid path, or
- Change the last screen of one of the paths.
If your design requires you to reuse the final screen, we suggest adding those paths to separate prototype blocks on the same maze.
