When selecting online slots to wager on, a player has to make some important decisions before he can start spinning the reels. These are known as betting options. They include the number of paylines, the number of coins per payline and the coin size. Most slots allow you to choose all three betting options. Some slot games will a fixed number of coins wagered per payline, usually one, thus eliminating this choice from the betting options. Some (but not many) slots that fix both the coin size and the number of coins, effectively freezing the line bet.
There are two terms that should be clearly defined at this point. The line bet is how much is wagered per payline and can be determined as the product of the coin size and the number of coins per payline. The total amount wagered per spin is know as the total bet, and it is the product of the line bet and the number of paylines selected.
Since it makes little sense to play the online slot game without enabling all the paylines, this will generally be something you are allowed to choose. You can only win from a payline that is enabled. Selecting all paylines is most important with progressive jackpot games, as you can only win the jackpot when the stated combination occurs in the highest payline. Selecting all paylines will increase the total bet per spin drastically, especially in a slot game that has 50 or 100 paylines. In such a game the player enable all paylines and reduce his line bet in order to reduce the total bet.

Everybody understands the concept of volatility in the stock market. This same concept can be applied slots games at an online casino. Some slot games that will either pay out large amounts or almost nothing in the short run. These are known as high volatility slot games. Low volatility games pay out small amounts regularly, and medium volatility games obviously lay somewhere in between.
The way to identify a slot game as high, medium or low volatility the player needs to check out the payout table. Check the payouts for five of a kind for the various symbols on the reels. This payout (known as a fixed jackpot) will be expressed as a multiple of the number of coins wagered.
The online slot games that are very high volatility are those games with the highest fixed jackpot of 50,000 coins or more
The online slot games that are moderate volatility are those games with the highest fixed jackpot of between 5000 coins and 10,000 coins.
The online slot games that are low volatility are those games with the highest fixed jackpot of less than 5000 coins. The slot games of this type are somewhat rare because such slot games offer little expectation to the players.
