Introducing The Game

How To Play
Select your stake by clicking the left and right arrow buttons on the stake. The stake value is displayed in the stake display. All payouts are multiplied by the stake of each individual spin.
Start The Spin
Press the Play button to start the spin at the stake displayed. The 5 reels will spin and then come to a stop, displaying the result.
x2 Wild
Wild appears on Reels 2, 3, and 4 and substitutes for all symbols except Scatter. All wins are doubled for every Wild.
Mystery Box™
Mystery Box appears on Reels 2, 3, and 4. Mystery Box will open to reveal another symbol. Whenever 2 or 3 Mystery Box symbols appear, they all turn into the same symbol. All wins are determined after the Mystery Box symbols have turned into other symbols.
Gamble Feature
Every win will enable the Gamble button. Press Gamble for the opportunity to go Double or Nothing up to 5 times with every win. In some cases the Gamble Feature may be disabled.
Scatter
Get 3, 4, or 5 Millionaire Scatters to win 7, 12, or 20 Free Spins, respectively. Scatter pays any.
Free Spins
A Multiplier Ladder with 12 rungs is enabled. Triggering with 3, 4, or 5 Scatters commences the Multiplier Ladder on Rungs 1, 2, or 3, respectively.
All wins are multiplied by the highlighted Multiplier. Every Scatter that occurs in the Free Spins increments the Multiplier Ladder by 1 rung. Every rung awards an additional Free Spin except rungs 4, 8, and 12, which award an additional 3 Free Spins.
Return To Player (RTP)
The Return to Player (RTP) is the theoretical statistical percentage of the total money bet in a game that is paid out as winnings over time. Values are calculated initially by dividing the total payouts by the total bets from a simulation of numerous game rounds. Values reflect the maximum expected RTP and do not change.
The RTP value is shown in-game.
