The Complete Guide to Video Slot Machines

Video Slot Reels

When Charles Fey invented the Liberty Bell slot machine in 1895 we doubt he had any idea of just how big his invention was. From that moment on slot game makers have been improving on his idea and finally the latest development - video slot machines.

There are thousands of different variations, some with up to 3025 winning lines and special additional bonus games. This makes for a high hit percentage and a more entertaining playing experience compared to the older style three reel games.

Here at we give you the history, show you how they work and teach you how to play. We have also included profiles of some of the most popular video slots from major manufacturers such as IGT, Aristocrat and Bally Gaming.

Frequently Asked Questions

Are the outcomes really random?
Yes, every spin is totally random and in no way effected by the amount of money you put in, the amount of your bet or the time between jackpot hits.
Are the symbols weighted like on three reel slots?
In general no. Because video slots have virtual reels they have no need to weight the individual symbols they just add fewer of the highest paying ones and more of the lowest to the virtual reel which can contain anywhere from 10 to hundreds of symbols.
Can you recommend a good slot machine system?
No. There is no system to beat the modern day slot machine that actually works. There are some people who use techniques to cheat but these are generally illegal and they tend to end up with a mug shot on the Nevada Gaming Commission web site.
Can the casino change the payout percentages of the games?
No, Each slot machine comes from the factory set at a specific payout rate. To change the percentage a casino would have to get a new gaming chip from the manufacturer. Note however that for example different machines with the same game can and do have different payout percentages. Generally each game comes in several RTP levels.
Is it legal to film my slot machine play at a casino?
There are no specific laws against this but almost all casinos have a policy of not allowing video recording on their property due to privacy concerns. We recommend asking before filming.
