The History Of Slot Machines
Slot machines or fruit machines, as they are known in England, have been around for over one hundred years. This is because of the excitement that they bring to the player. With each individual pull or game, there is a chance of hitting the life changing jackpot. The first slot machine was the liberty bell which was invented by Charles fey a German immigrant who worked as a mechanic in San Francisco in 1899. All slot machines both at land based and online casinos have descended in some way from the original liberty bell machine.
The Liberty Bell slot machine had three spinning reels. Diamond, spade, and heart symbols were painted around each reel, plus the image of a cracked Liberty Bell. A spin resulting in three Liberty Bells in a row gave the biggest payoff, a grand total of fifty cents or ten nickels. Calculating odds in those days was easy. 3 reels with 10 potential stops give the following odds: 10 X 10 X 10 = 1000 combinations. Only 1 of those combinations yielded the big jackpot.
In 1902, Slot machines were banned in many states. Charles Fey then had to get creative. He changed the symbols on his machines and started offering candy, drinks, and gum as prizes. The owners of the machines that were already out redecorated the wheels with pictures of the gum and fruit instead of the card suits. Cherries have remained a constant on slot machines even today, and the sticks of gum eventually changed into the bars that you still see on a lot of common slot machines.
Slot machines were not really popular until the 1970’s in casinos. The older machines were limiting, because the biggest reels had only 25 different stops, which gave 15,624 to 1 chance of hitting a jackpot. The jackpot had to pay out less than that in order for the casinos to make enough profit for the slot machines to warrant that kind of floor space.
Then the pinball machine company Rally, invented a new slot machine that had both electronic AND mechanical parts. The newer machines also allowed for bigger bets and larger hoppers which could hold larger payouts. This made slot machines more profitable.
The random number generator became popular in the 1980’s and everything changed. The random number generator is basically a mini computer that simulates the sinning reels from a computer program. This changed the entire face of casinos. The reels could be much larger than the actual reels, since they were powered by a computer program instead of a mechanism. The spin arms became unnecessary, because the spin button activated the random number generator program and the machines paid out a preset percentage.
The new technology has made it possible for the machine manufactures to produce virtually a unlimited number of attractive and entertaining slot machine games. Slot machines now take up over 80% of many casinos’ floor space. It’s eye candy of the highest order, and gamblers gobble it up as if it were popcorn.
Question... Setting a picture box to change pictures with a timer in Visual Basic? My assignment is to make a slot machine, I have done everything except make the pictures "spin" I wanted to do something like randomly show pictures in a picture box but I am unsure about how to set it up. I have 10 pictures in my resources and 15 picture boxes. I wanted to set the time so when you pushed the spin button the first row would move fast and the second row a little slower and so on. Any help would be greatly appreciated!

*I am still editing this post...
Dim Delayer As Long=1 Sub Timer1 Tick If Delayer >0 Then PictureBox1.Picture=Resource( RandomNumber ) If Delayer >1 Then PictureBox2.Picture=Resource( RandomNumber ) If Delayer >2 Then PictureBox3.Picture=Resource( RandomNumber ) If Delayer >15 Then
Delayer=1
Else
Delayer+=1
End If End Sub
------------------ The delayer adds one in each tick of the timer. Each picture box changed only after the delayer number reaches a point, causing the delay. For example, since the first picture triggers so long as the delayer number is > 0, it will change every time. If you want truly different spin speeds, use a different timer for each picture box. You can create timers in code, or just drop the controls on the form. Ahh, im tired with a crying infant at 5 AM, so my thinking process is not that clear.
