Players in 30 Carats start with exactly the same items — a colored screen to hide their goods, five gemstones of each color in play, and five gold nuggets — but they won't stay the same for long! After all, each player receives a secret valuation card, ranging from +30 to -30, and the gemstones matching the color of his screen will have this value at the end of the game. (Gold nuggets are always +10 points.) Do you need to sell or buy your initial holdings? And how do you find out the value of everything else?!
