How do I open the Construct 2 "Bejeweled" demo for the match 3 mechanic?

I see this thread in the Construct 2 part of the forum:

construct.net/en/forum/construct-2/your-construct-2-creations-23/bejeweled-plugins-demo-55828

And the demo is lovely. I would like to make use of this in Construct 3 but when I try to open it, I get errors for the missing Rex addons. When I try to add them, some aren't available for Construct 3 it seems? Is there a comparable demo for Construct 3 or this basic match 3 mechanic?

Thank you!

Have you tried the Poplab demo?

It's not the same mechanic, but the techniques used to compare tiles are the same.

Everybody thinks match three is a really simple game, but its not, in fact popular versions are horribly complicated.
