Progressive Jackpot Slots
A very popular type of slot with the biggest jackpots, progressives are number of machines running in a single network that uses a portion of the money inserted to continuously builds a jackpot until it is won.
These slot machines have more than one pay-line. The most common of these machines have three pay lines; one in the middle of the screen, one on top of it and one below it. If you spin a winning combination that lands directly on any of these lines you might win. The twist is, is that you can only activate all three lines if you insert the maximum number of coins into the machine. So if you insert only one or two coins (on a three coin max, three line machine) and you hit a winning combo on the top line, you may not win anything. But if you had entered three coins, no matter which line you hit, you will win. As you can see, the advantage to playing a machine like this is that you have more chances at winning, but remember, this is only the case if you play the maximum amount of coins.
This type of slot machine is very common in any casino. On these machines, the payout changes depending on the number of coins you have played. For example, if you hit a combination that pays out $20 and you've inserted one coin, you will win $20. But if you had inserted 2 coins before you spun the wheel you would've won $40 (2 coins times $20 payout) or $60 if your initial bet was 3 coins.
Bonus Multiplier Slots
This type of machine runs similarly to multiplier machines, but when the maximum number of coins is inserted and you hit a combination an extra bonus is added. For example, by inserting one coin you win $100, 2 coins you win $200, but if you've inserted 3 coins (the max) you win $500.
After reviewing these different types of machines you are ready to hit the slots, just be sure to read the machines payout schedule and know what type of game you are about to play.
