Multipliers

The majority of online slots games would have the multiplying feature available. The multipliers are triggered by some special symbols appearing on the reels. If a multiplying period is active, your winnings will be increased for a few spins. The size of the multiplier and the period that lasts are determined by the slot game and your stakes.

You will have greater chances to get a multiplier if you are betting 10 dollars per spin than if you are betting 1 cent per round. The slots machines that are not offering multipliers are considered ancient; therefore, you will have some hard times in finding such type of slot machine online. However, you could try it from time to time as a diversion.

Wild symbols

The wild symbol was introduced more than 10 years ago on the virtual slots machines. The symbol was considered a revolution in this field, as the winning chances of the players were greatly increased because of this symbol. The Wild Symbol acts like a joker for card games, as it substitutes any other symbol on the reels.

Moreover, a combination of three or more Wild Symbols will also trigger the bonus game on some slots machines. In some cases, such as The Incredible Hulk Slot Machine, the bonus game is complex. The multiplier could get to 25X, and you will have the chance to win the huge progressive jackpot available on some slots machines. Although there are still some machines and casinos that are not offering this facility, it is believed that the popularity of this system will surely grow.

Multiple pay-lines

The principle of multiple pay lines can't be applied in real casinos. Even the most complicated mechanic slot machine system can't calculate 25 pay lines at one time. The system is designed for online slots machines, and it surely contributed to the huge success of those online machines today. Some advanced slots games such as the Dolphin Slots Game offers hundreds of pay lines, but the majority of virtual slots machines are limited to 25-30 pay lines. This is more than enough for any established players, and you will be more than happy about your earnings on those machines.

Progressive bonuses

This is maybe the most important feature that attracts players in online slot machine gambling. The progressive bonuses could sometimes get to more than 700 000 dollars, especially for the Marvel Progressive Jackpot available with The Incredible Hulk, Spiderman and other Marvel based slots machines. However, some players are only hunting for smaller but more reachable bonuses, such as the in games bonuses. Even those possibilities can't be neglected; as we are talking about 5000 to 20 000 dollars on a single lucky spin.
