These crown symbols can only award a spin on the Jackpot Wheel and they serve no other purpose in the game. In order to be awarded one of the Hot Drop Jackpot amounts, you'll need to land three Hot Drop crown symbols. This means that the progressive jackpot is almost ready to be won. Additionally, you may see the outline around one of the jackpot totals glow bright gold. The jackpot total will continue to increase as usual, but it cannot be won until the 10-minute timer expires. One other interesting tidbit is that immediately after an hourly jackpot is awarded the jackpot will then be unavailable for 10 minutes. The maximum bet size varies by game, but all of the games offer bet sizes over $100, so they're certainly high-roller friendly. The odds of winning one of these progressive jackpots increases with your bet size (a person wagering $0.80 is twice as likely as a person betting $0.40 to win).
