Gamble Feature :
When a win comes up, you are given the change to bet on the credits you've just won.
The gamble feature allows you to select either the full amount, or you can select a half gamble by toggling the Gamble button. If a half gamble is chosen with an odd number, the gamble is rounded (a 5 credit win = a 3 credit gamble; a win gives you 8 credits, but a loss will leave you with the remaining 2 credits).
If you select the right colour (Red or Black), your win is doubled. If you select the right suit (Heart, Diamond, Club or Spade), your win is quadrupled. If you select the wrong item, you lose the gamble and it goes back to the main game.
You can take a win at any time, but if you win 5 times in the one gamble feature, the game ends automatically. You can't gamble more than $10,000 however (but, would you?!).
If you win a progressive jackpot on the machine, you can't gamble the win, even if you actually won credits on the same spin the jackpot went off. This game doesn't generally have a jackpot, it's up to the gaming venue if it's hooked up to one or not.
Power Pay feature :
The Power Pay button, if toggled on, doubles your total credits bet. Power Pay gives you the chance of winning free games.
Power Pay free games feature : If a Rhino and/or a Tree appear on both reels 1 and 5, you are awarded with 15 free games. You win a bonus of 2 times you bet before the free games start.
During the free games, a random multiplier comes up for each win, similar to the 'Spring Carnival' or 'Roll Up! Roll Up!' feature.
If you only have 1 credit left and can't hit the minimum bet to get rid of it, check to see Power Pay isn't enabled, since it doubles your bet.
