Yes, i believe the 9 jump rule is in both Froglet & Anti-Froglet.

I'm just guessing, but I believe the limit is in place because of programming issues. For example, I know in the past I had an issue with Halma also when trying to make a 10 jump move (only let me make 9). We got that worked out, but I'm guessing the 9 jump rule was put into place because of the same issue.
