Video slot machines are programmed to weigh symbols differently from each other, so that they appear more often on a payline than others. This results in the probability of hitting higher-paying symbols declining as you move down the reels. In the past, the only way to increase the likelihood of hitting a particular symbol on a specific line was to bet more coins per spin. Now, however, many manufacturers offer multiple paylines on a single reel and bonus features that multiply the number of possible combinations. In addition, companies like ReelMetrics and SG Connect are relying on player behavior data to help design games that engage players. This data can include how long players stay at a machine, what types of bonuses they trigger and when, as well as which features contribute to the most winnings. The data can then be analyzed to understand which types of designs and gameplay elements work best for different players.
