There's really not much to cover when it comes to slots strategy, from a pure numbers point of view. It's all random chance, as far as inserting money and spinning the reels,

For the superstitious out there who believe in hot and cold slots machines, as well as machines that are “due” to hit a jackpot, well, it’s a slightly different story. Slots enthusiasts have all sorts of strategies for playing slots, including decreasing or increasing the number of coins you play after a jackpot is hit, varying your bet based on how long it has been since the last bonus feature, and on and on and on.

Again, while the math may not support it, ultimately gambling is more about enjoying yourself than anything else, so if you love playing slots and feel that your "strategy" works for you, by all means, have fun and enjoy yourself.
