|Rare Gem type||Limited|
When the player begins a game with Crown Jewel activated, one of three special starting layouts appears. All three configurations include unique yellow gems that resemble crowns. A crown functions identically to a Flame Gem, except a crown clears all the gems within its row instead. The base value for clearing a crown is 6,000 points. While Crown Jewel is active, crowns replace random yellow gems throughout the game, and Flame Gems created using yellow gems become crowns instead.
After the Last Hurrah, a Coin bonus occurs in which nine crown icons appear in a 3×3 arrangement. When the player selects an icon, it reveals a numerical Coin value that is then added to the player's Coin total. The Coin payouts the bonus offers are 1,000, 5,000, 10,000, 15,000, 25,000, 40,000, 60,000, 100,000, and 250,000.
- The name of this Rare Gem is a pun on crown jewel, something that is the most attractive or valuable one of a collection or group.
