The Ultra Gamble Feature: This is the star of the show. After any winning spin, you are given the choice to either collect your win or click the "Gamble" button to try and multiply it. You'll be taken to a second screen featuring five face-down cards. Your task is simple: pick cards that beat the dealer's card. Aces are high.

This feature adds a fantastic layer of strategy and adrenaline to every win.


Scatter Symbol: The golden star symbol acts as the Scatter. Landing three or more Scatters anywhere on the reels triggers an immediate payout multiplied by your total bet, offering a nice boost outside of the payline wins.
