Maria La Piedra En Troya

INTRODUCTION

It is a single-player arcade machine in which, through the amount of the game, a time of use and enjoyment is obtained, and also occasionally, prizes.

Bets will be configurable by the user. Possible bets are: €0.20, €1, €5, €10, or €15.

The game consists of two parts: the lower game is the main game, and the upper game is the secondary game. To play both games, you need a balance, and additionally, for the upper game, you need Bonuses, which can be obtained in both the main and upper games, as we'll see later.

The image above shows the game screen layout, with the push buttons at the bottom of the screen, the played time indicator, the AUTO-PLAY and AUTO-RISK buttons, the volume, the main game reels with the payline marked in red in the center position, the payout plan, the nudge indicator, the PRIZE value indicator, BONUSES, BALANCE, and the MESSAGE/RISK PLAY marquee.

Configurable RTP per bet: 70% - 80% - 90% - 95% 

2. LOWER GAME

This is the machine's basic game, played on three reels with 16 symbols each, with prizes on the center line, nudges, and holds. Players can play whenever they wish and have sufficient funds by pressing PLAY.

This machine allows you to select your bet using the BET button located at the bottom of the screen. Possible bets (depending on the machine's settings) include:

0.20€, 1€, 5€, 10€ or 15€.

To begin the game, you must have sufficient funds to cover your selected bet and press the PLAY button. As mentioned previously, the main (lower) game takes place on the machine's lower reels, spinning them all and stopping on one of the many possible combinations. At the end of the game, the machine will indicate to the player whether they have won a prize.

When selecting a bet, the possible prizes will be highlighted on the screen, lighting up according to the player's choice.

2.1. Auto Play

The player has a mechanism to start the game automatically called AUTO-PLAY, the purpose of which is simply to start a game whenever the previous one has finished. 

With the indicator light in green (ACTIVATED) once the game is finished, a new game will begin with the current bet as long as the player has enough balance to cover it.

2.2. Roller arrangement

The lower game consists of three reels with 16 symbols each and a prize on the center line. Their arrangement is as follows:

2.3.Wild card

Both the left and right reels feature a wild symbol that combines with any other symbol to win a prize for the player. For example, if two bell symbols appear on two of the three reels and a wild symbol appears on the third reel, the player will win the bell symbol prize. Similarly, two wild symbols can win a prize when combined with any other symbol.

The wild symbol substitutes for any other symbol on the reels as long as it forms a winning combination with the other two. The wild symbol will never be used in combination with another symbol to hold two reels and spin the third reel for a possible prize.

2.4. Earnings Plan

Depending on the resulting combination on the center line, the player will win a prize according to the following payout plan. Bets will be configurable by the player; active bets will have this payout plan:

Table 1. Bottom game payout plan

2.5.Types of Print Runs

In the lower game, the following types of rolls can occur:

2.5.1. Direct Award

When any combination of the numbers described in the paytable lands on the center payline, the player wins an instant prize, either cash or bonuses. The machine indicates the prize amount to the player via the display at the top, along with a flashing of all the lights and special prize music.

2.5.2. Retention

If, as a result of the game, the player obtains two identical figures on 2 of the 3 reels in the center line, the game program allows the player, without changing the bet, to have two of the three reels with the same figure held in the next game, and therefore, the only one that spins is the third reel. 

The game program automatically holds the two reels with matching symbols. If the player does not want this option, or prefers to hold only one reel or none at all, they can use the ADVANCE/HOLD buttons located below the reels to unlock or lock any reel (up to two), thus enabling or disabling its spin in the next game. Similarly, even with all three reels unlocked, the bet for the next game cannot be changed.

After a game played with two or one reel held, the Advances option may be activated, explained in the next point.

2.5.3. Progress

If the player doesn't win a prize, but the machine detects that a few more spins of any reel could have resulted in a prize or the chance to hold two reels with matching symbols, the Nuzz-Off feature is activated. The machine offers a maximum of four Nuzz-Offs, indicated both audibly and visually by lights on the screen. Each Nuzz-Off corresponds to a positional spin of the selected reel, resulting in the next higher symbol on the payline.

The player will use the ADVANCE/HOLD buttons to move the reel as they see fit. There is also the option to activate AUTO-ADVANCE using the button of the same name, which will automatically spin the reels, always resulting in the best possible outcome for the player. If the button is solid, AUTO-ADVANCE is activated, while if it is flashing, it is deactivated.

The Nuzzle feature doesn't always guarantee a win on the center line; it can also award two matching reels for a second round with more possibilities. If, after using Nuzzle (either manually or by activating Auto-Nuzzle), the player lands two matching symbols on two of the three reels, the game will automatically retain those reels. 

2.5.4. Nothing

After their turn, the player does not obtain any winning combination or any other option for advancement or retention. The game is over.

2.6. Vertical lines

Certain reel symbols are associated with a vertical lines symbol (see image below). If this symbol appears on any reel, it will increase the vertical lines counter (up to a maximum of 9).

Vertical lines will be used in the top game. If vertical lines are used in the top game, the number of winning lines will increase from 5 to 8. 

Each roll of the upper game will decrease the counter by one.

As you will see in the game above, there is a figure that can also increase this counter. 

2.7 Mini games Bottom Game

The lower game on the machine features a special prize with the "access to the mini-game" symbol. If the player lands this combination on the center line, they will gain access to the Achilles Mini-Game if the final prize is in euros, or the Temple Mini-Game if the final prize is in bonuses.

2.7.1 Achilles Mini Game

The game always awards a prize of €. It consists of a draw among several items. The items will light up randomly and stop on the winning prize. The player can stop the game by pressing the PLAY/ACCUMULATE button. 

If the button is not pressed, the game will stop automatically after a few seconds.

2.7.2 Mini game Temple

The game always awards bonus prizes. It consists of a draw among several items. By pressing the PLAY/ACCUMULATE button, the player activates a roulette wheel that will eventually stop on one item. The prize will be whatever the stopped item indicates.

If the button is not pressed, after a few seconds the roulette wheel will activate and stop one of the elements, awarding the player the associated bonus prize.

2.8 Bond-Ups

The prizes highlighted in blue in the table will be included in the Sube-Bonos game:

If one of these prizes is won, the machine will offer the player the option to gamble it in a Bonus-Raise game, represented by flashing lights on the lower paytable. In this game, the player can choose to keep the prize (by pressing the COLLECT button on the lower panel) or gamble it (by pressing the PLAY/ACCUMULATE button on the panel). If the player presses COLLECT, the prize will be added to the balance counter. If the player presses PLAY/ACCUMULATE, the machine may award the next highest prize on the paytable, or a Bonus amount, which will be displayed in the upper left corner of the screen under the text “Message/Gamble Game” . 

If the player exceeds the threshold marked by the prize corresponding to the 3 green diamonds, the game becomes a seesaw game, offering the player the option of the next higher or next lower prize in the payout structure. If the player wins the next lower prize again, the game reverts to the bonus seesaw mode.

If you win one of the prizes highlighted in yellow, the machine will offer you the option to gamble it in a "Raise the Jackpot" game, represented by flashing lights on the paytable below. In this game, you can choose to keep your winnings (by pressing the COLLECT button on the bottom panel) or gamble them (by pressing the PLAY/ACCUMULATE button on the panel). If you press COLLECT, the winnings will be added to your balance. If you press PLAY/ACCUMULATE, the machine may award you the next highest prize on the paytable, or you may win NOTHING, which will be displayed in the top left corner of the screen under the text "Message/Game of Risk" . 

The game will end when the player obtains one of the following options:

• COLLECT: If the player decides to collect the prize, the game ends.
• BONUSES: If the player wins BONUSES as a prize for the game, the prize will automatically be converted into an equivalent amount of BONUS and the game will end.
• MAXIMUM PRIZE: If the player wins the maximum prize after climbing the payout ladder to the maximum, the prize will be automatically awarded and the game will end.

The cash prizes won in the Stop It game will also grant access to this game.

2.8.1 Self-Risk

The player has the option to activate AUTO-RISK using the indicator light at the bottom of the screen. With the button activated (GREEN LIGHT), all prizes submitted to the Up-Bonus or Up-Down game will automatically be risked in the Up-Bonus game until it ends. 

2.9 Bonds

Bonuses earned in the lower game can only be used in the upper game. Here's how to get Bonuses: 

• By winning on the center line, either by getting one, two or all three bonus symbols on the center line.
• Through a direct prize in the game. Winning Draw.
• Risking prizes in the Sube-Bonos game.

In this game, you play on all three reels, each with 16 symbols, but with prizes awarded for 5 paylines and 8 paylines if the vertical line counter is greater than zero. 

This game allows you to place various bets depending on the player's choice and the game's settings, provided you have sufficient funds and bonuses to maintain the bet. The possible bets are:

With the indicator light on in green (ACTIVATED) once the game has finished, a new game will begin with the current bet, provided the player has sufficient balance and bonuses to cover it. Winnings Plan

The following details the top-tier winnings plan:

3.9 Types of Print Runs

The possible combinations for the top game are:

3.9.1 Direct Award

The player wins any winning combination on the paytable on any of the 5 fixed paylines or 8 paylines (if the machine has vertical paylines). The prize won, or the sum of prizes won on more than one payline, is added to the payout counter at the top of the screen. An animation and flashing lights indicate to the player which payline or paylines have been won and the amount of the prize.

3.9.2 Nothing

The player does not obtain any winning combination on any of the 8 lines that make up the upper game. The game is over.

3.10 The journey

To access this mini-game, you must first obtain three "theme 1" symbols on any of the paylines in the main game. The game may randomly grant access to this mini-game, which replaces the main prize and gives the player the chance to win another prize of equal or greater value.

An audio announcement will lead to a new scenario with this mini-game.

The game always awards a prize of €. It consists of a draw among five elements. The elements will light up randomly and stop on the winning prize. The player has the option to stop the game by pressing the PLAY/ACCUMULATE button. 

If the button is not pressed, the game will stop automatically after a few seconds.

3.11 The Siege

To access this mini-game, you must first obtain three "theme 2" symbols on any of the paylines in the main game. The game may randomly grant access to this mini-game, which replaces the main prize and gives the player the chance to win another prize of equal or greater value.

An audio announcement will lead to a new scenario with this mini-game.

We will see a castle with three staircases, and prize amounts will appear randomly. Depending on the prize amount, prizes may appear on one, two, or all three staircases.

The player can stop the game by pressing the PLAY button. The final prize will be the sum of all the amounts currently displayed on the screen. 

Sometimes, the game can reward the player with bonuses.

3.12 Trojan Horse

To access this mini-game, you must first obtain three "theme 3" symbols on any of the paylines in the main game. The game may randomly grant access to this mini-game, which replaces the main prize and gives the player the chance to win another prize of equal or greater value.

An audio announcement will lead to a new scenario with this mini-game.

The game consists of choosing between three possible options. The player will activate the game using the ADVANCE or PLAY buttons, or by pressing the button on their chosen element. Winning a prize will advance the player to a new round, until all rounds have been played or EXIT appears next to the chosen option.

The final prize will be the accumulation of prizes from all rounds.

3.8 Mixed

In certain bets, when the player on a winning line gets three bar symbols that are not the same color, they will access this mini-game.

This mini-game will give a random prize that will depend on the bet. 

The game will take place in the ALPHA DISPLAY. 

In the payout plan, depending on the bet, the player will see what prizes they are eligible for. For example, bets that do not qualify for the minigame.

Example bet that if you access the minigame

3.9 Cumulative

The cumulative jackpot consists of 8 pieces in the upper game that will be completed when the cumulative figure is obtained on the reels of the upper game. 

Below is an example of cumulative:

When the figure of the cumulative game comes out, we will have an increase between 1 and 3. Sometimes it is possible to have larger increases of even 8 positions at once.

The accumulator bet is independent of the bet. Each bet has its own accumulator. 

When the accumulation is complete, an "EXTRA SPIN" label will appear; this will spin the reels and award a prize with or without a mini-game. 

3.10 Top vertical lines

In the top game we have a vertical line counter

This counter is shared with the lower game. 

In the top game, each time the vertical lines symbol appears, the counter will increment between 1 and 5.

When a game is launched in a higher game (regardless of the bet) this counter will decrease by one unit and the player will be eligible for 8 paylines (5 fixed paylines + 3 vertical lines). 

3.11 Double or Bonuses

Prizes won in the top game will be subject to the Double-Bonus game. This applies regardless of whether the prize is won directly (any of the five paylines) or as a result of the additional games in the top game. 

In this game, the prize money is divided into fractions based on the bet amount, and the player can win double that fraction or an equivalent amount of bonuses. At any point during the game, the player can choose to stop and keep the current prize amount.

The fractions that will be used as a reference are:

• 4€ à Bet 0.20€ + 1 Bonus
• 10€ to Bet of 1€ + 5 Bonuses
• 50€ to Bet of 5€ + 25 Bonuses
• 100€ to Bet of 10€ + 50 Bonuses
• 150€ to Bet of 15€ + 75 Bonuses
• 150€ to Bet of 15€ + 150 Bonuses

For each fraction of the prize, the player can decide whether to risk the prize by pressing PLAY/ACCUMULATE and get double the fraction being played with or an equivalent amount of Bonuses, or if they prefer not to risk and collect the prize by pressing COLLECT, and accumulating the prize in the balance counter. 

If the player does not want to risk any of the fractions of their prize and wants to claim the entire prize, holding down the COLLECT button will claim the entire prize instead of taking it in fractions.

If the player wins the maximum prize for the selected bet, the prize will be transferred directly to the balance counter, with no option to risk any portion of it. Similarly, if enough DOBLAs are won to reach the maximum prize for the selected bet, the game will end and the remaining prize will be collected. 

There is also a limit on the number of bonuses a player can accumulate, in this case 4000 bonuses. If the player exceeds this amount of accumulated bonuses, the Double Up or Bonus feature will not be allowed. 

3.11.1 Self-Risk

The player has the option to activate AUTO-RISK using the indicator at the bottom of the screen. With the button activated (GREEN INDICATOR), all prize fractions submitted to the Double-Bonus game will automatically be risked and will never be added directly to the balance counter, unless the player achieves enough consecutive DOUBLES to reach €500, in which case the game will end and the remaining prize will be collected.

3.12 Celebrations

The accelerations of the upper game are governed by the following parameters:

4 JACKPOT

Operators who have the Jackpot option can have this option enabled beforehand by requesting it from the fapicante.

Sometimes, in both lower and higher games, the game may award a JACKPOT prize after a non-winning combination. 

This prize is a common progressive jackpot for all players and for certain games, which increases with contributions from each game played, so the more games played, the faster the Jackpot increases.

The winning amount will be the one displayed on the “MESSAGE/RISK GAME” counter. 

The prize you are eligible for depends on the bet.
