In this third week of the casino slot reviews, we went shopping for uncommon titles. They are produced by some of the leading companies in the world of online casino gameplay. We looked through the libraries of Wild Streak, Aristocrat Gaming and IGT. We also picked a casino game each from Scientific Games and the American Gaming Systems.
#1 Red Baron Slot by Aristocrat
Developer Information
We’re pretty sure that you weren’t on the side of life when the first world war broke up. How grueling it was. With over 9 million lives lost, it’s one event too many to be erased in hindsight. However, many things stood out from the war and some included the efforts of the soldiers.
This is perhaps the singular motivation for Aristocrat Gaming, one of the leading online slot software providers. The company went in-house and developed the Red Baron slot machine themed after Baron Manfred von Richthofen. Baron was a German pilot known for being a high-scoring ace fighter.
Game Theme and Content
This slot game is themed after the pilot’s nickname of «Red Baron.» The name is in line with the red-colored aircraft he was known to fly during the war. In addition, it has historical, aircraft, war and military themes. All these underscore the era in which Baron existed and played a role.
RTP Percentage
The Red Baron slot is rewarding. Players receive up to 96% of their wagers. To lower the risks and barrier to entry, the provider kept the minimum bet at $0.01. You can bet a maximum of $2, although this figure can vary by many online casinos.
Volatility Level
There has been a debate on the actual variance of this best online slot. While some argue on the side of being high, others say it’s low. We checked and confirmed the volatility level to be low-to-medium. This makes it perfect for all kinds of players, amateurs and professionals alike to wager.
Unique Selling Points
Besides the central figure, it’s themed after, there are a couple of other features that stand the Red Baron slot out. One of such is the «return» of WW1 medals and a host of other bonus features. We discuss all that below:
| Selling Points | Description |
| Choose Your Mission | This is a feature that allows players to decide on which mission to execute. The higher the level or stage, the better the prospects and the wins. For example, Mission 2 requires collecting a minimum of 8 planes for a 15x the win multiplier, while the fifth mission requires 20 planes for a reward of multiplying the wins by 140 times. |
| Xtra Reel Power | By default, the Red Baron slot is a 5-reel game. However, there’s an option to adjust things with the Xtra Reel Power. By maintaining the middle row, it allows players to choose the number of reels to play and adjust the same accordingly. |
| Multi-technology Slot Game | Red Baron supports HTML5, Flash and JS technologies. These powerhouses boost intuitiveness. |
#2 Cleopatra Slot by IGT
Developer Information
International Game Technology (IGT) comes in second in our slot reviews for the third week. The company exists to deliver quality and entertaining gaming content devoid of manipulations. Instead, it enthrones responsible management and delivers classic slots and other kinds of games, while fostering player engagement.
Game Theme and Content
The Cleopatra slot centers on the character of Cleopatra VII Thea Philopator, the last active Hellenistic Pharaoh. Though dead since 30 BC, she has become a modern sensation, used as a reference point for encouraging women’s liberation.
IGT took the initiative to immortalize her further through a casino game that offers a mix of high entertainment value and player appeal. It draws the theme from ancient Egypt.
RTP Percentage
The Cleopatra slot machine returns 95% of the amount wagered. This is almost the average value for most slots, making it suitable for new gamers, casual players and highrollers.
Volatility Level
This best slot is in between low volatility slots and high volatility slots. With a medium variance, it’s ideal for players who want to test things out. That also appeals to players with little bankroll, as they can expect manageable wins.
Yet, the volatility level could spike when there’s a line switch. The medium variance is obtainable in the 20-pay line. But when switched to a single payline, the volatility becomes high. The latter also presents a risk of losing without being careful and experienced.
Unique Selling Points
Cleopatra slot machine rewards players with free games when they successfully land three tomb symbols on the reel. The reward also comes with up to 3x retriggers.
Other unique features are:
- Configurable maximum bet amount.
- It has many symbols, some of which are traditional Egyptian symbols representing wealth.
- The availability of symbols also means that the chance of forming a winning combination is high.
#3 Dragon Power Slot by Wild Streak
Developer Information
Wild Streak Gaming, a premier provider of third-party game design, is one of the studios owned by Bragg Gaming Group. It released Dragon Power to join the hundreds of slots in the portfolio.
But that’s not what stood the game out. The reason for the massive adoption can be linked to the four different jackpots up for grabs during the time the respin feature is put to use.
Game Theme and Content
You must have come across a slot game with two themes and that’s it. Yet, some go over and beyond. Here is one of such! The Dragon Power slot features multiple themes, drawn from Japan, China and Dragons. These are harmonized in a Chinese template, where detailed graphics and brocade backgrounds are the hallmarks.
RTP Percentage
This is a 95.69% RTP slot machine revolving around 5 by 3 reels and 50 active paylines. Players need to make a minimum wager of $0.5 and a maximum of $50 to qualify.
Volatility Level
The Dragon Power slot is a medium-volatile slot game, offering a fair balance between losing and winning. Those who get ahead in the game can benefit from the maximum payout amount of $5,000.
Unique Selling Points
Some users have blamed the provider for reducing the quality of the graphics, especially when compared to other titles. Aside from that, unlimited free spins are available upon making consistent wins with the higher multipliers.
Choice features like Golden orbs activate randomly at the start of the Dragon Power slot game. Tens of other symbols are available, including:
- Respin bonus triggered when up to six wild symbols land on the reels.
- Koi carp.
- Animal-themed symbols, such as a monkey, a tiger and a rooster.
#4 Capital Gains Slot by AGS
Developer Information
Money Charge is a family of jackpots developed by American Gaming Systems (AGS). The idea is to offer players more chances at winning their wagers on high volatility slots. The games batched here pack a punch in hardware configurations, a plethora of bonuses and the classic Hold & Spin feature.
Game Theme and Content
The Capital Gains slot is generally money-themed, with a particular concentration on gold. A good demonstration is the integration of a Hold & Spin feature that allows locking their credit prizes. You can play for free on the Play AGS website, after making an account and getting approval.
RTP Percentage
The RTP is pegged at 95.96% in the Capital Gains slot. Below the top value, but above the average. Seize the opportunity and the jackpots to win big!
Volatility Level
As one can expect, the variance is high. This can be traced back to a wide range of factors, most especially the RTP, which can be volatile because of the abundance of bonus features involved in the gameplay.
Unique Selling Points
The Capital Gains slot machine can be played in different ways, such as video slots, Eilers Hits or as a social game. The integrated PowerXStream method supports the 243 paylines to move from left to right.
Talking about the betting ways, players win whenever they can match matching symbols on the reels.
#5 Dancing Drums Slot by SG
Developer Information
Can drums dance? Well, it appears the ones from Bally Technologies (acquired by Scientific Games) can. The Dancing Drums slot is an online slot developed by Shuffle Master, before its acquisition by Bally Technologies. The latter would also be acquired a year later by Scientific Games.
Game Theme and Content
This is one slot machine too many. The theme of the Dancing Drums slot is primarily Asian but also has notes of happiness, oriental and wealth. You can also see some gold coins popping around the screen.
RTP Percentage
This is a progressive slot designed to reward the players. Get set to receive $9.6 for every $10 wagered.
Volatility Level
We must mention that the variance of the Dancing Drums slot is on the medium scale. Though not a new online slot, this volatility level is perfect for players who don’t want to play all their hands. Seize the opportunity to manage the extreme fluctuations that potentially come with unbalanced bet sizes and winning combination rates.
Unique Selling Points
The Dancing Drums slot offers 243 reel ways, the famed Fu Babies symbols jackpot and bonus feature triggers. Up to four variants of free spins are offered, have fixed paylines and are playable on either the 5 by 4, 5 by 3, 5 by 5 or the 5 by 6 layouts.
