Most casinos have regular promotions that change with every new machine that they add to their portfolio. You will find some free slot games in this section, though there are always certain games that are always available.
Some of the symbols used for playing slots are the familiar circular, triangular, square, and rectangular icons. These are accompanied by numbers that give the exact payoff amount for every spin. On the horizontal axis, you will see numbers that identify the specific reel symbol. For instance, if you see a 3 on the vertical axis and a 6 on the horizontal axis, this means that the reels will rotate around a single symbol on the horizontal axis, which gives you that single symbolized payout.
Other symbols include a vertical bar or line that gives you bonus rounds. Bonus rounds give players double and triple payouts depending on how many times you spin the reels.
