With the rise of online gaming, players have an increasing choice in slots. In 2021, over a dozen new slots are added by developers each week, adding to an already dazzling amount of online slots to choose from. This staggering amount of slots makes it harder to find your personal favorites. That’s why we’ve put together a quick guide to the most popular slots of 2021. Not only do these slots offer hours of playing fun, each of them can be played as free slots. This way you can try our shortlist and decide on your personal favorite.
Since its release in June of 2016, the Fire Joker slot has been a world-wide fan favorite. This slot from developer Play ‘n Go uses the classic three-reel structure to create a simple but enjoyable playing experience. As an ode to truly classic slots, the symbols and fire environment are recognizable.
With an RTP of 96.12% and a maximum win of 800x your bet size (between $ 0.20 and $ 100 per spin), Fire Joker offers a rather straight-forward slot on every account. The Fire Joker substitutes all other symbols in a combination, and getting two reels filled with the same symbol gets you a fire respin that offers a chance for a field full of the same symbol. This in turn unlocks a multiplier wheel, where you can multiply your win by 10x.
In 2021, you can find plenty of slots using a Hold & Win feature, but Wolf Gold has been handing out great wins using this feature since 2017. This slot from developer Pragmatic Play gives you different roads to big wins, with the Hold & Win feature taking the center stage.
The excellent max win potential of 5,000x is balanced out by the average RTP of 96.01%, but the medium variance helps accept this tradeoff. On top of the usual wins, Wolf Gold offers three jackpot wins.
Most of the game plays like your average slot, with the chance to win free spins, too. Aside from the normal symbols, you’ll see a full moon with a random amount appear. Getting six of those moons in view unlocks the Hold & Win feature that brings you the sum of all amounts and the chance to win jackpots up to 1,000x your bet.
Book of Dead
If the Hold & Win feature seems popular lately, the slot Book of Dead has inspired an entire catalogue of clones. Publishing Book of Dead in early 2016 truly cemented developer Play ‘n Go as one of the big names. You’ll play with a 96.21% RTP, and a high variance and max win: 5,000x.
The popularity of Book of Dead (and its many rip-offs) is due to the bonus game. Unlocking the bonus takes putting three wild scatters in view. This leads to the bonus. Before the bonus spins start, one symbol is selected. After each normal round, the selected symbol will expand on the entire reel, giving you a win on all ten win lines. Combine this with the highest symbols on five reels, and you’re looking at wins up to 5,000x your bet in one spin.
