If you are playing in a multi coin and multi line machines, it is advisable to play one coin each on as many lines as you like. These slot machines give you betting flexibility you never had before. Not only can you choose how many lines to play; now you can also choose to play more than one coin per line. You will have to decide how many lines to play and how many coins to play per line. These machines have the most complicated pay tables of any slot machine. Have patience to study the pay table. You must look carefully to see if there's a payout, like a scatter pay, that's available only when you play all lines.

As far as multiline machines are considered, one can play more than one line if landing-winning combinations on pay lines didn't activate bothers you. If not, you can play one coin on one line.

How to play in different types of slot machines

If you are playing on progressive machines, always play with maximum number of coins. If you are not following this advice, you're only increasing the jackpot for someone else with no chance of winning it yourself. These machines can be recognized by the LED displays advertising the ever-increasing jackpots, some life changing, that you can win by playing the machine.

If you are playing in a straight multiplier machine, always play one coin at a time because the payback and hit frequency are the same regardless of the number of coins you play. Another type of machine is known as bonus multipliers. In these machines, it is always better to play one coin at a time. The main reason behind this is that the chances of hitting a payout with a bonus are so small, it's not worth the extra risk. Some people argue that you're playing at a lower long-term payback when you play only one coin at a time on a Bonus Multiplier. That statement is partially true. But, again, how times does a player hit the top jackpot?

Buy-a-pays is another type of machine. In this machine the best option is to play with maximum coins. The main reason is the increase in payback and hit frequency purchased by the additional coins can turn a terrible machine into a good one. These machines can have very high hit frequencies.

A hybrid is another type of machine where the rule is to play just enough coins to activate all winning combinations. The main reason is that the extra coins are rarely worth playing in a multiplier, and hybrids are multipliers when you're in the multiplying section of the paytable. When you are playing in a hidden buy-a-pay machine the general rule is to play with maximum coins because the feature activated by playing the last coin frequently makes the last coin pay back over 100%.
