Mina de Oro Bingo

1. INTRODUCTION

This is a single-player gaming machine where, through a bet, you can obtain a certain amount of time to play and enjoy it, and occasionally, cash prizes.

1.1. Cardboard

The user can decide how many cards they want to play with in the next game. They can close any cards they want using the "X," but there must always be at least one open card. The maximum number of cards per game is 4. The activated cards can also be modified in the "Cards" section of the Menu.

The image above shows the layout of the game screen, with the buttons and counters at the bottom, and the game cards, drum, and winnings plan at the top.

2. BASIC GAME

This is the machine's basic game, which consists of one to four cards that are automatically marked as each ball is drawn from the drum. For this game, the number of balls in the drum and the number drawn are:

• Balls in the drum: 60
• Balls extracted: 30

It can be played whenever the player wishes and has sufficient balance according to the selected bet, by pressing PLAY.

The bet is defined per card. For example, if a user plays 4 cards and selects a €0.20 bet, they will bet 5 cents per card. The minimum bet is €0.02 (one card worth €0.02) and the maximum is €30 (four cards worth €7.50 each).

To start the game, it is essential to have sufficient funds to cover the selected bet and press PLAY. As already mentioned, the basic game of the machine is played on the cards, by drawing balls from the drum and marking the numbers on the cards. Each time a mark forms the shape of a prize defined in the winning plan, it is celebrated, increasing the WON counter by its value and marking the prize obtained in the winning plan in red.

Each card shows the amount bet for having that card open, but when a prize is won, the indicator changes and shows the prize amount won with that card.

As soon as a prize is awarded that contains another prize, the latter is discarded, and only the value of the first prize is won. For example, if a BINGO is awarded (a picture with all the numbers on a card marked), the BINGO will be paid, and the remaining prizes on that card will be discarded, since the BINGO already contains all the pictures.

At the end of the game, the machine will indicate to the player, on the WON counter , the final prize obtained.

Upon launching each game, the PLAY button changes to STOP , allowing the player to stop the ball drop and observe the current game status. Once the drop has stopped, the button changes to CONTINUE . Pressing it resumes the ball drop.

The player can change the order of the numbers on the cards by clicking on any of them. This will randomly arrange the numbers differently on the four cards. This can also be changed from the game MENU.

2.1. Possible prizes

If we look at the screenshot above, colored lines are shown on the cards. These lines are an aid to the player and show the possible prizes they could win if a specific ball is drawn. The drawing shows which figure they are eligible for, and a counter indicates the prize amount. Each line is colored according to the prize it indicates.

The profit plan also highlights the last position remaining to achieve a specific prize by highlighting it in yellow.

For example:

• It is marked with the same color as the prize and the shape of the possible prize is drawn (cross)
• The missing ball to win the prize is marked on the profit plan illuminated in yellow and indicated on the card by the orange box.
• The orange box includes the prize corresponding to that figure (0.40)

The prize counters can be of different colors, indicating that with that ball the prize awarded would be the highest of all those the player is eligible for.

In the example above you can see that the number 2 is marked in a different color indicating the prize is higher than the number 50.

2.2. Autoplay

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

Pressing the button will display a menu so we can select how many automatic games we want to run (with a maximum of 100 games) and if we want to purchase all the extra balls (explained later).

Once the amount is selected, the menu will close. The PLAY button will display the number of times the game will be played. Once the game is over, a new one will begin with the current bet, provided the player has enough credits to cover it.

2.3. Profit plan

Depending on the figures formed on the cards, players will win prizes according to the winning scheme. It consists of 16 figures , which can be seen below.

Below you can see the table of prizes according to the bet:

2.4. Extra balls

Once the 30 balls have been drawn from the drum for this game, if the player has the possibility of winning a Tails figure or higher with one ball missing, he will have the possibility of buying EXTRA BALLS .

Players can purchase as many balls as they want (maximum 14) . The cost of each ball is displayed in the center of the drum, which varies dynamically depending on the probability of winning and the winnings. The value of the extra ball is calculated by looking at each of the prizes that can be awarded with each of the balls yet to be drawn. All these prizes are added together, and this sum is divided by the number of balls yet to be drawn. Finally, the value is increased by multiplying it by 1/0.90 to adjust the RTP. The minimum value of an extra ball is €0.01, and the maximum is €500 x the value of the ticket.

Some balls have no cost and will be indicated as such.

Additionally, the AUTO, PLAY and BET buttons become EXTRA NO and EXTRA YES respectively.

Clicking on EXTRA YES will purchase a new extra ball and clicking on EXTRA NO will complete the purchase of extra balls.

Occasionally a JOKER BALL will come out, this ball allows the user to transform that ball into the number of the card they want (that has not yet come out of the drum).

The player can choose the number by clicking on it directly. If you click on the JOKER BALL or EXTRA YES, the ball will transform into the number that gives the highest possible prize at that time.

2.4.1. Extra Ball Calculation

The parameters for calculating the value of an extra ball are as follows:

• Possible prizes (PP): Prizes that can be obtained with just 1 more ball.
• Current Total Earned (TGA): Amount of prize money that has already been won
• Number of Free Numbers (CNL): This number indicates the number of numbers the extra ball could have. The formula would be (Total number of balls in the drum (60) - number of balls drawn).
• C1/C2/C3/C4: carton number
• Remaining balance from the previous ball purchased (RSABC): The amount left over from the previous ball purchased. When calculating, some balls may have several extra decimal places. These decimal places are saved to be added to the next extra ball.

The value of the extra ball is calculated as follows:

For each card, the current winning total for that card is subtracted from the possible prizes. The result is then divided by the number of available numbers. If the current winning total is greater than the possible prizes for that card, the current winning total will not be taken into account in the calculation of that card.

This will be calculated for all cards with a possible prize; if there isn't one, nothing will be calculated for that card. The values obtained will be added together and then multiplied by (1/0.9) to adjust the RTP.

Additionally, if we have any remaining ball from the previous ball purchased, this will be added to the calculation of the extra ball.

If a ball can award a bonus as a possible prize, the average prize of that bonus must be taken into account to calculate the possible prize for that card.

For example, if the prize awarded with a ball is 100 and the average bonus value is 50, the possible prize would be 150.

3. BONUS

Once the game is over (including the purchase of Extra Balls), if the player has rolled a token marked "BONUS" on the payout plan, they will have access to a Mini Game. Mini Games are not part of the base game and increase the game's final prize. The tokens and bonuses that grant access are as follows:

3.1. Bonus Slots

The game will display a slot machine and a prize plan. The game consists of launching games by pressing PLAY. Depending on the combination of symbols that appears in the center of the reels, the prize associated with the prize plan will be awarded. The prizes won will accumulate until the cross symbol appears in the center of one of the reels. At this point, the game will end. The final prize will be the cumulative sum of all the prizes won. If the button is not pressed, the game will remain in the same state until the player takes action. If the auto-play button is active, the game will automatically launch games after a few seconds.

3.2. Convoy Bonus

In the minigame, different carts appear, the first three of which will be lit and each with an associated prize. As time progresses, the first cart will turn off and the fourth cart will turn on, displaying another prize. The second cart will then turn off and the fifth will turn on, displaying another prize. And so on for all the carts. There will always be three illuminated carts. Pressing "PLAY" will pause the game and award the prizes currently on screen. If the button is not pressed, the game will remain in the same state until the last three carts are reached, at which point the game will stop and the prizes shown on screen will be awarded. If the auto-play button is active, the game will not stop until the last three carts are reached. Occasionally, the game may award a free prize.

3.3. Bonus Enter the Mine

Several mines appear in the minigame. The player can select the mines by clicking on them or using the PLAY button. Each mine can have a prize or an "EXIT" associated with it. The game consists of selecting mines to obtain prizes. The minigame ends when all the mines have been selected or when an "EXIT" appears on a mine. The final prize will be the total of all the prizes obtained. If the button is not pressed, the game will remain in the same state until the player performs an action. If the auto-play button is active, the game will automatically select mines after a few seconds.

4. SUMMARY

If a bonus has been accessed during the game, a summary box will appear at the end of the bonus, detailing the player's final prize. The box will display the following order (as long as it has been awarded):

1. Won in Game: The sum that has been obtained on the cards through the figures of the profit plan
2. Bonus Wins: The total amount earned for each Bonus separately. If more than one entry has been obtained for the same Bonus, its result is multiplied by the number of entries. For example, if we win three CUADRA prizes and we win 100 in the Bonus, the final Bonus prize will appear as 300 (100 x 3).

RTP = 91.51%
