Not necessarily, but if you keep the template the way it is and play without Jenga it might be a little weird for the kids haha.
The only reason I did Jenga was as a physical point reward system instead of the usual bomb game where the computer gives points. I would recommend just removing the slides related to Jenga and do another point reward system, like darts. If you don't have a dart board you can draw one on the board and get them to throw a piece of paper scrunched into a ball.
