In all jurisdictions, payoffs are required by law to be random. I also think that this is actually pretty close to optimum for inducing people to keep playing. The sort of programming you are suggesting would be illegal.

Also, even the reel slots that you find in casinos are all run by computerized random number generators now. The reels are really just a display device. The original slot machines were mechanical, pulling the lever spun the reels, and where they stopped spinning determined whether you got payed or not. For awhile some slots were electro-mechanical: An electric motor started the wheels spinning, but where the wheels stopped when they ran out of momentum still determined whether you got paid. The electronic random number generator is what made the huge jackpots possible. You can't set up a mechanical slot to have a low enough probability to allow multi-million dollar jackpots.
