Again, this is due to the rapid generation of random numbers. Playing faster will not increase your chances of winning. The RNG will generate thousands of numbers between the spins of even the fastest player. While a faster player may seem to win more, it's simply because they've spinned more for a given amount of time. The hit frequency is based on the number of spins, not time.
Lets take a simplified example of a three-reel machine.
A fair number of these possible results will give smaller, partial payouts, but there's only a 1 in 27,000 chance that the combination of numbers that represents the machine's jackpot will be generated. Given the random number generation, luck is as involved with slot play as it is with table play. However, the key point with slot machines is that they are set up with different payback percentages and hit frequencies. But loose isn't always a good thing if you're looking for a hefty jackpot. You may come out ahead, but you'll be less likely to hit a sizable payoff that's worth writing home about.
