The phrase "multiple win lines" refers to multiple lines in an online slot, running in different directions, where a combination of symbols on these lines triggers a win. Unlike traditional slots, which only featured a single win line, modern online slots tend to have at least 9 to 25 win lines. The more win lines a slot has, the greater the chances of hitting a win, but the stakes also increase accordingly. You can choose the number of active win lines in order to personalize your gameplay and maximize your shot at winning.
