I agree it's definitely too busy. I say keep it simple; at the top, have one box with three columns. Top row are names, bottom row the scores.
Directly under that, a slightly larger box (height-wise; same length), with prizes for the round. No icons, just text. Think what "High Rollers" used to do, whether it was the backlit slides or chyroned. Or "(Classic) Concentration" for that matter. Keep the boxes opaque so that you can still see the people frolicking around the island or beach. :-)
Make it unique but not detracting.
