On video slots, the symbols vary according to the theme of the machine, but classic symbols include fruits, bells, and stylized lucky sevens. Some slots have multiple pay lines; each one gives the player a different chance of winning based on what combinations appear on the reels. Some of these payout percentages are posted on the machines, but most aren’t. Tracking your results over time can help you figure out the probability of hitting a certain payout combination, but that’s still only an approximation. Using central flow management, however, is more accurate and can save you time and fuel by keeping you on the ground instead of in the air, waiting for a slot.
