This one's the grandest of Kate's Roundominoes series. It has 83 acrylic pieces in six luminous transparent colors plus black and white accents. They include 1 through 5 rounds, 1 through 4 bridges, and 8 new shapes called doopers, that are doublerounds with extra bridges (white pieces at left). They have droll beach-scene names (Kate did design this in Florida). Can you find the bikini top? Halter top? Rubber ducky? Fish? Flying fish? Hairdryer? The 16" acrylic tray, black or white, is supplied with fitted see-through reversible black/white lid and display stand. Recommended for teen and adult puzzle lovers (or a precocious six-year-old!), 1-6 players.$225
