Online slot machine rules are those key decisions, which one must consider if he is a casino slot player. Some say that playing with maximum coins really makes a difference and some say that it is hard to make out the difference. However, whatever, knowing the rules can really help to get through this dilemma. On a casino floor, one can found many casino machines with many more new ones too. Every machine may sound different like one is straight multiplier slot machine; another is double diamond machine and so on. On every machine, the numbers of coins, which are played, get multiplied to the payoff making a fantastic winning combination.

One must make a point that playing more than one coin per spin is expenditure, as the average return of the machine can never change with the number of coins played. Therefore, on a straight multiplier machine, there is no mathematics of playing more than one coin per spin. In machines like bonus multiplier, one can receive bonus payoff for playing maximum number of coins. Where as in popular three-coin Red White & Blue slot machine, hitting 7 red, white and blues gives 2400 as the payoff for one coin. This list goes on like 4800for two coins and so on.

To be eligible for bonus payoff, it is not compulsory to always play maximum coins on a bonus multiplier machine. This will cut the bank on the number of spins compared to single coin play. However, eagerness also matters. If one is not able to take the risk then single coin play is the safest way to enjoy the game.

Another category is buy-a-pay. Here one can make additional winning combinations by playing maximum coins. The two-coin sizzling sevens are an example for this.
