Slot Machine Odds - Can They Be Calculated?

In the early days of slot machines calculating the odds of a game was very simple. Unfortunately all modern slots are powered by a random number generator and have weighted combinations which means you cannot in any way work out the game odds. Many "Slot Systems" say otherwise - they are wrong.

Slot machines that were made prior to the random number generator was used can be analyzed to find the odds of any single combination being hit. This is due to the fact that all symbols have the same chance of appearing on the pay line. You can simply count the number of symbols on the reels and work it out from there.

For example lets say you have a slot machine with three reels and on each reel there are 15 symbols. This makes 3375 (15x15x15) different possible combinations. Hence the chance of hitting the top jackpot would be 1 in 3375.

Back to modern day slots. There are many slots systems for sale that still want you to believe that casinos have antique slot machines on the floors. While there are still spinning reel type slots they are NOT the same as their antique relatives.

While the spinning reels have been left in place to give the illusion of the original games, all modern day slots use RNG's so their odds cannot be calculated. We can however tell you that in general the odds of hitting the top jackpot on most land based casino slots is no better than between 500,000 to 1 and 1,000,000 to 1.

Of course even with these long odds many players hit big jackpots on a daily basis. It all comes down to one thing - being in the right place at the right time. Luck can strike at any moment when playing slots ...
