Casinos strive to maximize the number of players who play their slot games. Yet they must be cautious about raising the house advantage too much because it may frighten away some of their customers. Players who perceive price increases may move to another casino, which would cost them revenue.

This is why casinos tend to increase the house edge of their slot games only slowly and carefully. They want to maintain the image of a fair game, while also increasing their profits.

As a result, many slot designers have tried to create more entertaining machines by adding new features such as video monitors and group competition. They have also incorporated pop culture themes in an attempt to appeal to younger generations of gamblers.

When a machine is unable to pay out winning combinations, it is said to be on a “taste”. The taste is the amount paid out to keep the player seated and continuously betting.

A taste may be caused by a faulty door switch, reel motor failure or simply running out of paper.
