The idea is nice, for children, beginners but, I think, quite limited for adult or serious/worlds play?
If I understand well, you target the center obviously and depending where you land you have "stuff to do" (like small contests) idea sounds good to me too.

This could be enhanced and more funnyWe should enhance this for a more funny and
unserious play, for example what I have in mind: the player knows only what happens if he hit the center, then the others "holes stuff to do" would be re-arranged/re-generated at each round... (in some logical way like with different levels of "stuff to do", near the center:hard stuff to do, medium: easy stuff, far from the center: boring stuff to do... )
