This 5x3 slot machine from NetEnt has 20 paylines and a plethora of features to keep you engaged. It is a fantastic addition to the NetEnt portfolio.
Every wild is a Falling Wild, which means it will trigger respins for extra winnings if it appears twice in a row. Two consecutive wilds will also prolong the reels, increasing the chances of a payout. To win the Minor, Mini, or Major jackpot, you must collect scatters and coins.
WMS's Raging Rhino slot machine is one of the company's best-known products. This popular slot game, which is played on a 6x4 grid, provides 4096 possibilities to win as well as a free spins feature that may result in some substantial payouts.
If you like slots with wild animals on the reels, this one is a good one to play. However, do not be fooled by these lovely animals; it is the diamonds and acacia trees that will net you the highest rewards. These play the roles of the scatter and the wild card, respectively, in the game.
Just like it happens with movies and TV series, there's no reason why slot game creators can't utilize cartoons as a source of inspiration for their titles.
Playtech's designers were tasked with turning Seth MacFarlane's iconic show, American Dad, into a memorable challenge by translating it into an entertaining and dynamic video slot game.
Due to the low volatility and high return to player (RTP) of American Dad, it is possible that players will win a number of consecutive prizes when playing this slot machine. You will have a great time gambling with the many bonus features and other gimmicks included in this video slot.
We believe this to be a great game that deserves its place in this month's list of the most popular slots in 2022 -even for those players who have never watched a single episode of American Dad in their lives.
Twin Spin Megaways
The Twin Spin Megaways slot machine is based on NetEnt's famous Twin Spin game, which has now been given a megaways makeover. Describing this game is very simple: it's just a must-try for fans of Megaways games. BARs, bells, and 7s are among the symbols included.
Additional features include 15 free spins, wild multipliers, and other bonuses. The game's centrepiece is the remarkable Twin Reel feature, which locks at least two reels together to create similar symbols.

The good news is that if the prospect of wearing your finest singlet and shooting some baskets seems a little too much like hard labor, then Basketball Star is here to help you out. This wonderful slot game will really pay you for getting your hands dirty on the basketball court.
Microgaming, the company that made Basketball Star, has used the 243 ways to win technology again. This five-reel slot can be played for as little as 50 cents per spin.
Basketball Star puts the ball back in your court with over 40 wild symbols on the reels waiting to be spun plus the popular Rolling Reels feature.
In addition to the excellent visuals — the basketball court background is visually appealing – the sound effects of the audience roaring are particularly effective in encouraging you to keep going when the going gets rough.
Finn and the Swirly Spin
People who try new things to change things up and make the game more interesting are always welcome in our book. We've seen a number of games recently that leverage cluster pay concepts, where clusters of symbols anywhere on the screen may be used to trigger awards. This kind of gameplay may be used in many ways, and we'd want to see other creators experiment with it.
Finn and the Swirly Spin by NetEnt is one of the most popular games to experiment with this concept.
While this is a machine with a traditional theme and some cute symbols, there is much more to it than meets the eye.
The presence of a swirling pattern on the reels is really essential to the game's operation, as it allows players to experience a high level of suspense as each cascading match brings them one step closer to opening the door to a spectacular free spins round.
