Slot has been riding on a crest of a gambling popularity wave since they moved online in 1996. They were popular in their physical form before this and even when they were first introduced to the world back in the 19th century, they took the public by storm then too. It is not clear why these games are so popular but a few pointers suggest that it is slot promotions and bonus rounds and actual thrill of each spin that keeps the crowds hungry for more. 

Digital Slots 

Digital technology introduced into the world of gambling back in 1996, really helped to ignite slots back into life, so much so, that they now proudly stand as the number one draw in the gambling industry. The revenue generated by them has given slots developers bigger budgets to play with and the knock on effect has been more extravagant slots for punters to enjoy. 

Furthermore, the continued success of the industry now means that various slots developers can afford to purchase the rights to hit TV shows and major movie franchises and bring them to the reels. Already numerous films such as Terminator 2, Gremlins, The Goonies, Jurassic Park and superhero movies such as Justice League, have become top slots with memorable free spins bonus rounds. 

Different Types Of Free Spins 

Bonus rounds have become bigger and better and this makes triggering them an even more satisfying experience. The potential for big wins has risen too, but some of the classic slots still hold much appeal for punters. Free spins in bonus rounds usually come with multipliers and wilds that increase the chances of building winning symbol combinations on the reels. Wilds that roam during a set number of spins or for the entire bonus can land punters some healthy wins. This also applies to sticky wilds and expanding wilds. 

Top Slots 

Classic games like Book Of Dead, Cleopatra, Fluffy Favourites, Top Cat, Ted, Wish Upon A Jackpot, Book Of Ra and Immortal Romance are slots that have become firm crowd pleasers. This is why they still remain as headliners at many online casinos despite them not being new entries into the slots world. 

What makes them appealing are the bonus rounds, and they all consist of free spins. Cleopatra rewards players with 15 free spins and an x3 multiplier is added to every winning spin. Book Of Dead has a bonus round that consists of 10 free spins with a special expanding symbol feature. Book Of Ra does the same and along with Book Of Dead, and most of the above-mentioned slots, the bonus rounds can be retriggered. Top Cat, Ted and Wish Upon A Jackpot actually have different types of bonuses, but the most rewarding ones are the free spins bonuses. Fluffy favourites offer 15 free spins that are activated by 3 or more pink elephant wilds. Immortal Romance has a chamber of different types of free spins packages and this needs to be unlocked, by regularly triggering the bonus round.
