Three Hot Games for October 2021

Each month we bring you a selection of games that we believe all players should discover for themselves at Spin Rio Casino. For October 2021 we have picked Evolution Gaming’s Speed Auto Roulette, Reactoonz from Play’n Go and Starburst from the famous NetEnt. If you’re looking for something new to play, then read the following before heading over to the casino to try them for yourself.

Speed Auto Roulette

Speed Auto Roulette is a huge hit with roulette fans thanks to its ultra-fast pace. One could even think of it as a successful marriage between Speed Roulette and Auto/Slinged Roulette. The game is designed to satisfy true roulette aficionados, thanks to its real wheel, and those who love speed, as the lack of croupier results in a betting time of just 15 seconds.

Speed Auto Roulette uses a slingshot mechanism that ensures that every single round follows a strict schedule. The ball spins automatically based on a precise timeframe. As mentioned, the betting time is 15 seconds whilst a full round lasts for about 30-35 seconds (depending on how long it takes the ball to come to rest).

The Evolution title is available on all platforms including mobile, desktop and tablet. Moreover, the table game is available 24/7 with around 2,500 spins occurring on a daily basis.

The game itself uses the standard European roulette wheel, meaning there are 36 numbers plus a single 0. The game has very much been designed for old-school roulette players. That is to say, there are no bonuses or additional multipliers available here; simply pure roulette. The main attraction, as mentioned before, is the speed at which rounds occur.

Evolution Gaming Speed Auto Roulette allows players to wager by selecting a chip value and then placing it on the betting area. The betting range starts as low as €/$0.10 and rises to a maximum of €/$500. This makes the game an ideal choice for both low and high rollers.

Whenever you hover your mouse over an eligible bet, the numbers which the bet covers will be highlighted. You can also click on through to some betting shortcuts, such as the “Evens” bet, which will place wagers on all the even numbers on the table.

Another appealing factor is the Auto Play functionality. Clicking on Auto Play allows a player to set a wager and then sit back and watch as the game continuously places it on each round until the predetermined number of rounds have been played or the player stops it manually. Lastly, you can also view game statistics. This will provide you with on previous rounds and a breakdown of various percentages. However, while this can be interesting, our advice is to avoid becoming too carried away, as each round in roulette is entirely independent of those that have come before.

  • Fast Paced
  • High RTP of 97.30%

Moving away from table games, we turn to Reactoonz from Play’n Go. This alien-themed video slot takes you on a cascading journey based upon the ever-popular cluster pays mechanic. The designers at Play’n Go truly got everything spot on with this title and you are sure to love the colorful little alien characters who accompany you on the reels.

Reactoonz plays out on a 7x7 grid with wins being awarded for landing clusters of at least 5 matching symbols. The only requirement is that the symbols touch one another, either horizontally or vertically but not diagonally.

When wagering on Reactoonz, you have the option to place bets ranging from as little as €/$0.20 to a maximum bet of €/$100 per spin. There is also an autoplay function, giving you the chance to choose set 10 and 100 spins in action. You can also set win and loss limits so that the autoplay function knows exactly when to stop spinning based on your preferences.

Reactoonz has an RTP of 96.51% and is considered an extremely high variance slot. In terms of maximum win amounts, you can bag a staggering 4,570x your stake on every spin or cascade.

As mentioned, the slot offers cascading reels. This means that after every win, the winning symbols are blasted off your screen, making way for new ones to drop down and occupy the empty positions. This could result in an additional win.

There is also a meter that charges up after every win. When it is fills, you could trigger one of four unique features. The rewards include extra wilds, symbols transforming into matching ones, low value symbols removed, or a wild placed in the center of the grid while transforming everything diagonally from it to the corner position into the same symbol.

There are also a number of minor bonuses such as random wilds added to the reels or a massive Giantoonz (2x2 in size) forming with a 2x multiplier attached.

There is an innocent cartoonish feel to the slot with a synthetic soundtrack playing in the background that sets the right tone. The most rewarding symbol of the lot is the Pink Alien, who pays out 1.6, 3.2, 4.8, 8, 12.8, 32, 80 or 1,200 times your total stake for landing 5, 6, 7, 8, 9, 10+, 12+ or 15+ symbols on the reels. Lastly, Reactoonz is also fully compatible with mobile, desktop and tablet devices as well.

What we like:

  • High RTP of 96.51%
  • Brilliant Theme and Design
  • Many Bonus Features involved

What we don’t like:

  • No Free Spins


Last but not least, is Starburst from NetEnt, one of the most successful online slots of all time. The video slot is played on a basic 5-reel, 3-row grid whilst offering a fixed 10 paylines. In order to form a winning combination, you’ll be required to match at least 3 symbols on adjoining reels. Moreover, it is also an All Ways Pays slot, meaning you can form winners from the 5th reel moving from right to left, as well as the standard left to right from the 1st reel.

Starburst gives players the option to wager anything ranging from as little as €/$0.10 to a maximum bet of €/$100 per spin. Just like with Reactoonz, this makes the title ideal for both low and high rollers. There is an option to play with auto play, giving you a choice of between 10, 25, 50, 100, 250, 500 or 1,000 auto spins. You can also select win and loss limits, so that the game knows exactly when to stop the spins from automatically beginning. 

The maximum win amount for this title is 500x your total stake. The other noteworthy thing here is that the RTP is rated at 96.09%, meaning it’s just about average. Moreover, the volatility is listed as low to mid-level.

When looking at the bonus features for Starburst, there is one that truly stands out. Namely, the Starburst Wilds. The Starburst Wild symbol, which is unmissable as it’s the shiniest of them all, can land on reels 2, 3 or 4 only. When it lands, it substitutes for all the standard symbols.

The Starburst Wilds feature is triggered whenever a wild lands on the reels. The wild expands and the entire reel becomes wild. Following this, you are given a free re-spin. During the re-spin, if another wild lands, you’re given another re-spin with 2 wild reels.

This means that you could potentially transform all three inner reels into wilds, which will certainly boost your chances of landing a big winner. If you manage to fill the grid with Wilds and the BAR symbol, you could be looking at the maximum win amount of 500x your total stake. Sadly, the feature ends when a wild fails to land on a re-spin.

Despite being released in 2012, the slot still looks fresh and modern. Better yet, it is fully compatible with mobile devices as well as desktop and tablets. As mentioned, the most valuable symbol is the BAR, which pays out 5, 20 or 25 times your total stake for landing 3, 4 or 5 respectively. As for the theme, well, just like Reactoonz, it is set in outer space. However, instead of aliens, you’ve got beautiful stars and a soothing soundtrack playing in the background.
