Yes, I have found that it brings users back more often which ends up helping out all around, as those users end up playing more of the 1v1 games as well.

The forever guess mode also was a late addition, mainly added it because my daughter was enjoying guessing more than drawing.

When she got home from school, she would grab my phone and guess all of the initial rounds that I hadn’t got to yet and leave the drawing to me. So I built that mode for people who didn’t feel like drawing at the time, but also works as a gap filler for folks with no active games.
