A gaming system implementing a base game and a feature game. More specifically, the present invention provides lipase inhibitors containing at least one of proanthocyanidins represented by the formula:wherein R1 and R2 independently represent H or OH, and R3 and R4 independently represent H or a galloyl group; as well as foods and beverages and pharmaceutical compositions containing said lipase inhibitors. The ability to use flexible polymers to form the polymeric replica facilitates industrial-scale processes utilizing the highly-ordered block copolymer films.
