The Multiplier feature can boost your winnings anywhere from 2x to 100x. Wild symbols substitute for any other symbol to complete winning combinations.
There are also bonus rounds — many slots unlock a separate bonus game outside the main gameplay, offering even more chances to win.

This feature is hugely popular in games like Gates of Olympus and Sweet Bonanza.
