Game Rules


5-Reel, 25-Line SlotProgressive Jackpot

5-Reel 25-Line Slots

The aim of the main game in Esmeralda online slot is to match symbols on paylines across the reels. You can also win up to 70 Free Games and a share of the Progressive Jackpot if you play for a higher bet. Fans of online blackjack and poker will also enjoy the Double Feature, where you can double your winnings on the turn of a card!

To Play the Game:

  • Start by using the +/- buttons on the Line Bet Box to increase or decrease the Line Bet. Choose the Number of Lines by using the +/- buttons on the Lines Box. You can play between 1-25 paylines. When you add a payline in this manner you will be able to see to the shape of the different paylines on the reels. You can also select your paylines by choosing one of the numbers from the side of the reels. Please Note: If you select, for example, 20 lines from the side of the reels this will also activate all paylines below that number (i.e. 1-19).
  • The Total Bet for each spin is calculated as Line Bet x Number of Lines.
  • Press Spin to start the game. You can also spin the reels by using the Bet Max button – this will spin the reels at the maximum number of lines for your chosen bet.
  • You can set a predetermined number of spins to be played consecutively by using the Autoplay function. Select the Autoplay button and choose between 10-99 spins to be played through. You can also set Autoplay to keep spinning until a Bonus Feature has been awarded. Press Stop to cancel Autoplay at any time.
  • Spins and reel animations can be accelerated by using Turbo Mode.
  • All winning combinations and their values are displayed in the Paytable. All Line Wins are x the Line Bet, whereas Scatter Wins are x the Total Bet. You can access the Paytable by clicking on the Info button on the bottom left of the screen.
  • Only the highest win is paid on any payline. Multiple wins on different paylines are possible, these are added together and paid as a Total Win. The Total Win will be displayed in a box on the bottom of the screen.
  • After a winning spin, the winning combination will be clearly highlighted on the reels.

Info Page:

When you select the Info Button it will open up the Info Pages. These are:

Paytable Page: Displays the winning symbol combinations and gives information on the Free Spins Bonus.

Jackpot Page: Provides information on the Progressive Jackpot.

Double Page: Explains the rules of the Double (Gamble) Feature.

Paylines Page: Provides a graphic and gives information on the different paylines.

You can exit the Info Pages and return to the main reels by selecting the Exit button from the bottom of the screen.


Paylines are the pathways that matching symbols must follow across the reels to form winning combinations. You can view the paylines in the Info Pages are by actively pressing the +/- buttons on the Lines Box below the reels.

Line Wins can only be awarded on active paylines. These wins are multiplied by the Line Bet and paid according to the Paytable. Scatter Wins are an exception to both these rules. Scatter Wins will be discussed in more detail below.

Wild Symbol:

The Wild Symbol – represented by the Esmeralda Symbol – can substitute for all other symbols to help form winning combinations. However, the Wild Symbol does not substitute for the Bonus Scatter Symbol.

Five Wild Symbols on an active payline will award the Progressive Jackpot.

Please Note: you must make the qualifying bet to be eligible for the Progressive Jackpot.

Scatter Symbol:

The Scatter Symbol also acts as the Bonus Symbol. The Scatter Symbol appears stacked across all reels. If you land between 5 - 7 Scatter Symbols anywhere on the reels you will win 2x your Total Bet. If you land 8 or more Scatter Symbols you will be awarded the Free Games Bonus as well as the Scatter Win as displayed in the Paytable.


Esmeralda online slot offers a Progressive Jackpot award. This Jackpot is built up by taking a small percentage of each wager made by all players and placing it into the Progressive Fund. The Casino will provide a base amount (called a seed) to ensure that the Progressive Jackpot will still be a large if won twice in quick succession.

If the Jackpot is won, by you or someone else, all players playing the game will be notified.

Please Note: To qualify for the Progressive Jackpot award you must play the maximum number of lines and one of the four highest coin levels. Each coin level corresponds to a different Jackpot award. This information is displayed in the Jackpot Info page.

In Esmeralda online slot the Jackpot is funded and awarded as follows:

Seed (base amount provided by casino):

25,000 x Line Bet.

Contribution Rate (percentage of each wager taken to fund Jackpot):


Win Condition (what is needed to win the Jackpot):

5 Wild Symbols on an active payline.

Win requirement (how to be eligible for Progressive Jackpot award):

Play maximum number of lines at one of the four highest Line Bet amounts.

Please Note: In the event of disconnecting from the game in the middle of a spin, the casino software will remember the exact point in the game before the disconnection. Therefore on re-establishing a connection you will continue your spin and play for the same Jackpot award.

Please Note: if the Jackpot is removed, i.e. the game is discontinued, the casino will be obliged to inform all players.

Free Games:

If you land 8 or more Scatter Symbols anywhere on screen the Free Games Bonus will be awarded:

  • The amount of Free Games will depend on the number of Scatter Symbols in the triggering spin:  
    • 8 Scatter Symbols = 15 Free Games.
    • 9 Scatter Symbols = 17 Free Games.
    • 10 Scatter Symbols = 19 Free Games.
    • 11 Scatter Symbols = 20 Free Games.
    • 12 Scatter Symbols = 22 Free Games.
    • 13 Scatter Symbols = 25 Free Games.
    • 14 Scatter Symbols = 35 Free Games.
    • 15 Scatter Symbols = 70 Free Games.
  • In the Free Games Bonus the reels will spin in a different way – some upwards some downwards.
  • In the Free Games Bonus the Wild Symbol can also substitute for the Scatter Symbols to help form Scatter Wins and win more Free Games.
  • The bets and paylines for the Free Games Bonus are the same as the triggering bet. This cannot be adjusted.
  • The remaining Free Games are displayed in a box on the top left of the screen. When all Free Games have been played all wins will be calculated and displayed as a Total Win.
  • If the Free Games Bonus has been triggered in Autoplay mode, you must click Start to initiate the Bonus. Autoplay will resume once the Free Games Bonus has ended.


After any win (apart from the Jackpot) you can choose to enter the Double Feature. It works as follows:

  • After a winning spin the Double Button will flash. If you wish to gamble your winnings select this button, otherwise press Spin to collect and spin again.
  • On pressing Double, you will be taken to a new screen with 5 playing cards face down. The leftmost card is the dealer’s card. The objective of the Double Feature is to pick a card higher than that of the dealer’s card.
  • A correct guess will double your winnings, after which you can Collect or try to Double again.
  • An incorrect guess forfeits all winnings and returns you to the main game.
  • Picking a card of the same value results in a tie, your stake will be returned and you can exit or try again.
  • You will also be given the option to Double Half, which protects half your winnings and lets you gamble with the rest.
  • You can collect at any time before the dealer reveals their card.
  • You can keep doubling your winnings until you guess incorrectly, or reach the Double Feature Limit. This information is displayed in the Double Info Page.
