Game Rules

Secrets of the Amazon

5-Reel, 20-Line SlotSingle Feature Game

The objective of playing Secrets of the Amazon slot is to land matching symbols on the reels. The game offers a Free Games Bonus with up to a 50x Multiplier of all wins, meaning that the payouts on offer with Secrets of the Amazon can dwarf those from regular casino games like online blackjack and roulette.

How to Play:

  • Set the bet for each payline by using the +/- buttons underneath the Line Bet Field.
  • Choose paylines by using the +/- buttons underneath the Lines Field. You can also choose paylines by clicking on the numbers 1-20 on the sides of the reels, although be aware that clicking a number will also activate all paylines numerically below it.

Note: Total Bet = Line Bet x Number of Paylines.

  • Press Spin or Bet Max to spin the reels. Choosing Spin will spin the reels with the current selected paylines. Choosing Bet Max will spin the reels with all 20 paylines activated.
  • Use Auto Play if you wish to play a set number of spins to play through automatically. You can choose from 10, 25, 50 or 99 Auto Spins. When Auto Play Mode is on, the Auto Play button changes to Stop. Select it if you wish to exit Auto Play Mode.
  • Press the Turbo Mode button if you wish to speed up the reel animations to enable faster results.

Note: A winning combination will be clearly highlighted on the reels, with the total win shown in the Win Field.

Note: All possible payouts for Line Wins and Scatter Wins are listed on the Paytable. Line Win payouts are x Line Bet. Scatter Win payouts are x Total Bet.

Info Pages:

The Info Pages are launched by clicking the Info button on the bottom left of the main screen. You can flip through the different pages by using the arrows on the bottom right of the screen. Press Back to exit and return to the reels.

Paytable – displays all possible winning combinations and their payouts.

Moonflower Bonus – describes the awarding of the Moonflower Bonus.

Moonlight Free Games – describes the rules and special features of Free Games.

Paylines – illustrates where all 20 paylines appear on the reels.


Paylines are the directions that matching symbols must follow across the reels to pay as Line Wins. Only the paylines that you bet on can record Line Wins.

Please note that there is a difference between the Line Bet and the Total Bet. The Line Bet is the amount wagered on each individual payline. The Total Bet is the total amount wagered on all active paylines, i.e. Line Bet x Number of Paylines.

About Payouts:

Every possible winning combination and their payouts are listed on the Paytable. Line Win = Payout x Line Bet. Scatter Win = Payout x Total Bet.

Only the highest value Line Win is paid on each payline. Multiple Line Wins can be paid on different paylines. These are added up – along with any Scatter Wins – and paid out as a total win.

A Line Win must begin on Reel 1, moving left to right across the reels in a chain of symbols on a payline.

Wild Symbol:

The Wild Symbol can substitute for all other standard symbols to form the best possible Line Win on a payline. A Wild Symbol cannot substitute for the Scatter Symbol.

When one or more Wild Symbols substitute in a Line Win, the value of the payout will be doubled for that Line Win.

Wild Symbols can also form their own Line Wins with a separate payout.

Scatter Symbol:

The Scatter Symbols do not need to fall on any paylines to award a payout. Three or more Scatter Symbols in any position on the reels will award a payout (x Total Bet).

Three or more Scatter Symbols will also award the Moonflower Bonus (Free Games).

Moonflower Bonus:

The Moonflower Bonus is the first stage of the Moonlight Free Games Bonus. When it is awarded – as explained above – press Click to Start. This will launch a new screen, where you will be prompted to choose one of three Moonflowers. Picking a Moonflower will reveal the number of initial spins you will have for the Free Games Bonus. The possible number of spins that picking a Moonflower can award depends on the number of Scatter Symbols that awarded the Bonus:

Scatter Symbols

Possible Number of Free Games







When you have made your choice, the number of Free Games will be revealed and begin to play automatically.

Moonlight Free Games:

Moonlight Free Games start directly after the Moonflower Bonus. The total number of remaining Free Games is shown on the bottom left of the screen. The Multiplier for Free Games will start at x1 for the first spin, and increase by +1 for every spin thereafter. Thus, any wins achieved in the second spin will be doubled, any wins achieved in the third spin will be tripled and so on.

If you land three or more Scatter Symbols, you will be awarded extra Free Games. This will be the same amount that was awarded in the Moonflower Bonus. The Multiplier does not change initially, but will still rise by increments of +1 with each extra free spin.  

Please note:

  • The maximum Multiplier that can be achieved is x50.
  • The maximum amount of Free Games that can be played is 50.
  • Free Games are played at the same Line Bet and active paylines as the triggering spin.

When all Moonlight Free Games have been played through, a results screen will appear detailing the total win from Free Games and the triggering spin (Game Win). Press Continue to return to the main game.

The theoretical RTP (Return to Player) is 95.28%.
