A: The higher the jackpot, the greater the odds. Look at this simplified example for the explanation: Imagine a machine with a $1,000 jackpot accepting $100 single coin bets. One pull and you win $1,000 or lose $100. If, on the average, players hit once every 11 spins, the return would be $1,000 for $1,100 wagered, or almost 91 percent. Now if multiplied by 100 the slot would offer a $100,000 jackpot, but it would require 1,100 spins at $100 each for a total of $110,000 wagered and $100,000 won = the same 91% return percentage. You might want to ris $100 for one chance in 11 to win $1,000, but do you want to risk $100 for one chance in 110,000?
