Hi to everyone here! I'm a newbie! I just wanna ask help from you especially from the administrator regarding my machine problem...

I am asked by my proffesor to create a slot machine program.
This is how it goes..

The simulation starts by presenting the player with a menu of how much money to play for the round. The user has 3 options as shown in this sample run.

Rarely did anyone dare to take action and cheat the slot machine. There are few examples, or at least they are not known to the public – that someone managed to cheat the slot machine. The reason for this lies in the fact that today’s slot machines are a matter of technique and programming. So it’s no wonder that mostly the house always wins. Slot machines are some of the most lucrative games on the casino floor for both the players, the house and cheaters. Even though they’re electronic, slots easily attract as many cheaters as.

Notice that the program checks whether the player entered correct values or not. If an incorrect value is entered, the program prompts the player to enter again.

If the player enters 10 or 20, the program will randomly generate 3 symbols. The symbols that can be generated are: APPLES, ARCHER, HEARTS, SMILES, or STARS!. However, the 5 symbols mentioned do not appear uniformly. The table that follows summarizes the statistics:

Symbol Chances of Appearing
STARS! appear 10 % of the time
SMILES appear 30 % of the time
HEARTS appear 30 % of the time
ARCHER appear 30 % of the time
APPLES appear 60 % of the time

The player wins money if the 3 generated symbols result to a lucky combination. If a lucky combination is generated, the prize in the 1st Credit is awarded. If the same lucky combination is obtained for the next round, then the 2nd Credit Prize is awarded.

Lucky Combinations

1st Combination
STARS!-STARS!-STARS!
1st Credit: $500
2nd Credit: $1000

2nd Combination
SMILES-SMILES-SMILES
1st Credit: $250
2nd Credit: $500

3rd Combination

1st Credit: $150
2nd Credit: $300

4th Combination
ARCHER-ARCHER-ARCHER
1st Credit: $100
2nd Credit: $200

5th Combination
any combination of a pair of any symbols except for APPLES
1st Credit: $20
2nd Credit: $40

6th Combination
a combination of SMILES, HEARTS and ARCHER
Credit: Especial Event if bet is $10
Credit: Especial Event 2 if bet is $20

The values above only hold if the user plays for $20. If the user played for only $10, a regular prize of $50 is given for the 1st to 4th combinations, and $10 for the 5th prize. Note that there are no 1st and 2nd credits for $10 games.

The 6th lucky combination gives the player access to a special event. This happens regardless of the user's game mode choice. There are two special events. If the user entered $10 the credit will be the special event 1 and if the user entered $20 the credit will be the special event 2( Actually my teacher said that I have the option to design whatever special the user will encounter.. since I know how to program ROCK-PAPER_SCISSORS Game and HANG-MAN GAME.. I chose them for my SPECIAL EVENT 1 & 2). If the user wins the special event 1, an award of $150 will be given to the player. If the user wins the especial event 2, an award of $300 will be given.

All unlucky combinations offer $0.

The program should continue to execute until the user chooses to quit (by entering 0).

I already know the codes on the first part of the program. I have already tested ran and debugged the first part wherein the menu is displayed.
I mean this part..

Now my problem is on the part of randomizing the symbols to be displayed..
I tried one of this codes..

Fortunately this code worked! But my problem is: 'How am I going to edit the appearances of each symbol?' Like making the symbol 'STARS!' appear 10% of the time and 'APPLES' appear 60% of the time.. is my function: 'getRandomNum()' wrong? Am I going to change it?.. or what..
plss help me... regarding this matter.. I would really appreaciate if you could help me.. Thanks a lot!

P.S.
You could also send me the source code for my slot machine program.. If you think you know the shortest/ briefest way to code it... then you could send it to me.. if you like :cheesy: .. I Would really really apreciate it! THANKS! :lol:

easy, give stars a larger numeric range. since apples are hard to get, make them 0 -9, then alot 10-69 for apples. and allow the other in the 30% remaining. any number randomly generated has a greater chance of falling in the larger block then the smaller one. therefor, you …

Well first off 60+30+30+30+10 does not equal 100 so its kind of hard to say that SMILES HEARTS AND ARCHERS happen 30% of the time.

Group them into the 30% and then pick one out of the 3.

This will help with the distibution with APPLES appearing most …

I don't do homework or write code for people, sorry. However; I am willing to aid in any problem you are trying to solve (as long as some genuine effort is put forth). I feal the best way for someone to learn is for them to complete the project on their own merit. (THINK FOR YOUSELF) If they dont wish to learn or do the work they should not have accepted the project or taken the course!

Recently one of our blog readers raised this question that there are some errors when buying a used slot machine. Though his query was related to his IGT Double Diamond model 96435800 reel slot machine which he had bought but here we are catering to some of the most common errors buyers face when they buy a real slot machine specially a refurbished ones. You can try to fix these errors by doing the following actions as given against each error. Also there are many superb videos online that teach you how to fix these errors.

EEPROM Device Error

EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified. However, an EEPROM chip has to be erased and reprogrammed in its entirety, not selectively. It also has a limited life – that is, the number of times it can be reprogrammed is limited to tens or hundreds of thousands of times. In an EEPROM that is frequently reprogrammed while the computer is in use, the life of the EEPROM can be an important design consideration.

A special form of EEPROM is flash memory, which uses normal PC voltages for erasure and reprogramming.

Here is the video how to fix this error

Error on door of slot machine

Many times when the display on the door indicates an error condition, open and close the door to reset the game and clear the error. Open the main door which clears the current game information and a “0” appears in the Coins Played window. Closing the door resets the game and the reels will spin and stop in their last valid position. The error code should clear and the digital display returns to normal game play.

Error Code 12 Battery Voltage

Slot Machine Source Code

To fix this error turn power off and then turn power on if the battery voltage has dropped below 2.9 V. Also replace ASAP due to possible RAM (Memory) corruption. Open / close door to clear and also Replace 3.6 V Lithium battery on CPU board.

Coin Errors

For coin errors see that comparitor is seated in all four acceptor clips and that acceptor does not have coin(s) jammed or the coin optics below comparitor is not blocked You can ensure toggle power switch is in activated position if installed.

Coin Out Tilt Hopper

Check for and clear any jammed coins in the coin out channel. Also see that the coins are not jammed behind hopper knife or see that the coin out optic sensor is not blocked by dust. If so you can replace hopper coin out optic.

Error in Extra Coin Out Hopper

To fix this see that the hopper motor brake functions properly. Check the coin wiper/ knife for jams and if so adjust them if necessary.

Hopper Empty Error

This is the most common error that new slot machine owners will have because the cash out button was pushed and the number of coins in the hopper is less than the total credits to be paid out. You can open the main door and check the hopper for coin level (your hopper will not dispense all of the coins), refill and close the main door. You may have to do this several times for all of the credits to be paid out.

Reel Tilt Errors

You will find that there are reel tilt errors and for this see that whether the designated reel is misaligned or malfunctioning. Also check if the reel is not unplugged. You can switch connectors from one reel to another, determine if error follows change of connectors. Try replacing reel assembly or optics if error stays with bad reel. Also clear Ram and see if it works again.

Error Codes and Fixes

Slot Machine C# Code

During the process of clearing error codes, you may encounter multiple 6x series errors. Here are few common ones and their fixes

CMOS RAM Error

This means Bad (or cleared) CMOS RAM data You can Press test button 3 seconds Error code 61-1 should now be displayed. Now close door, turn and release reset key once. Same for game data reset.

Bad Game EPROM or Data EPROM Error

Check circuit board and replace Game EPROM. For Data EPROM error check circuit board and replace Reel EPROM

Bad EPROM Device or Bad EPROM Data or Game Type Mismatch

Press self test switch for 3 seconds If error will not clear replace EPROM Also if the processor could not read or write to the named chip Press test button for 3 seconds Error code clears from display. Casino deposit bonus best.

Most of the errors can be resolved with little help but many need technical knowledge. Remember that if you are on a warranty or not the place or online site where you purchased a used slot machine is there to assist you with trouble shooting and repairs. They can guide you over the phone or send some mechanical and technical person to do so.
