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 modern day slot machines that actually works. There are some people who use techniques to cheat the machines or force coins to drop but these are all 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 four or five payback levels.

Where can I buy a video slot for my home?
We cannot recommend any particular company as we have never bought a game for home use. In many states it is illegal to own one. Also See : Buying a video slot
