While slots machines may seem a lot alike–and they most often are–there are a number of differences between video slots and reel slots, and they are typically the way that payouts are calculated. In the case of reel slots, the only way to win the maximum jackpot offered is to play the maximum number of coins possible, which is typically 3, 4, or 5 coins per spin. With video slots on the other hand, the value of the fixed payouts are calculated by multiplying the number of coins in each line that is being bet on.
What this means is that on a reel slot, it would be advantageous for the player to play with the maximum number of coins possible. Conversely, with video slots, it is much better to play as many of the individual lines as possible, but in terms of calculating the payout amounts, there is actually no advantage to be gained by betting more than one credit per line. That being said, there are certain cases in which video slots machines require the maximum number of credits per spin to be inserted in order to win the biggest payout.
