Relax Gaming Review – Best Slots, RTP & Features

Full review

Relax Gaming review: what you need to know

Relax Gaming is a leading online casino game developer and content aggregator, best known for the Money Train series, Temple Tumble Megaways and its Dream Drop jackpot network. Founded in 2010, the Malta-based company has developed from a specialist poker technology supplier into an established name in the global iGaming industry.

Unlike many traditional slot studios, Relax Gaming operates two complementary businesses. It develops its own casino games while also distributing content created by independent developers through its Silver Bullet and Powered By Relax programmes.

This combination gives the company a distinctive position in the market, although players should distinguish between games developed directly by Relax Gaming and third-party titles distributed through its platform.

In this Slotinia review, we examine Relax Gaming’s history, most popular slots, bonus mechanics, RTP, volatility, jackpot products and approach to game development.

History of Relax Gaming

Relax Gaming was founded in Finland in 2010 by Patrik Österåker and Jani Tekoniemi.

The company’s original focus was not online slots. Instead, it developed technology for online poker, later expanding into bingo and casino content.

As the business grew, Relax Gaming established operations across several European locations, including Malta, Estonia, Sweden and Serbia.

The company’s expansion into proprietary slot development marked an important change in direction. It began producing games under its own brand while continuing to build technology for other operators and studios.

In 2021, Kindred Group completed its acquisition of Relax Gaming, further strengthening its position within the international gambling industry.

Today, Relax Gaming is recognised for its original slot portfolio, progressive jackpot products and content distribution network.

Best Relax Gaming Slots

Relax Gaming has produced several influential online slots. Its portfolio ranges from relatively straightforward cascading-reel games to highly volatile bonus-driven releases with substantial advertised maximum payouts.

The following titles are among its most recognisable.

Money Train Series

The Money Train franchise is arguably Relax Gaming’s best-known slot series.

The original Money Train introduced the Western-inspired setting and Money Cart bonus concept that would become central to later releases.

Money Train 2 expanded the formula with additional special symbols and more complex interactions.

Money Train 3 continued the development of the franchise, introducing further bonus mechanics and a maximum advertised payout of 100,000×.

Money Train 4: The Last Stand increased the maximum payout to 150,000×, making it one of the developer’s highest-paying releases.

In September 2026, Relax Gaming released Money Train 5, introducing Standard and Ultra modes with maximum advertised payouts of 50,000× and 100,000× respectively.

The series is particularly associated with its Money Cart bonus, where special symbols can collect, increase or redistribute values.

Different instalments introduce their own variations, so the exact mechanics should always be checked in the individual game.

Temple Tumble Megaways

Temple Tumble Megaways is another important title in Relax Gaming’s catalogue.

It combines an ancient temple theme with the Megaways mechanic and cascading wins.

Winning symbols disappear, allowing new symbols to enter the grid and potentially create additional combinations.

This cascading structure gives the game a different rhythm from conventional fixed-payline slots.

Temple Tumble helped establish Relax Gaming’s reputation for accessible mechanics with additional layers of bonus potential.

Book of 99

Book of 99 is notable for its unusually high theoretical RTP of 99.00% in its published configuration.

This makes it an interesting contrast to the developer’s more volatile, bonus-focused releases.

However, RTP is a long-term mathematical measure rather than a prediction of individual results.

Players should also verify which RTP configuration is offered by their chosen casino.

Other Notable Releases

Other recognisable Relax Gaming titles include Money Cart, TNT Tumble, Snake Arena and the Dream Drop series.

These games demonstrate the developer’s range, from cascading mechanics and bonus collections to progressive jackpot systems.

The portfolio is broad enough to appeal to players with different preferences, although the studio is particularly associated with feature-rich games.

Relax Gaming Slot Features

Relax Gaming is known for combining familiar slot mechanics with additional features that can significantly change the gameplay.

The exact mechanics vary between titles, but several approaches appear regularly throughout its portfolio.

Money Cart Bonuses

The Money Cart feature is strongly associated with the Money Train franchise.

These bonuses typically involve special symbols carrying values or abilities.

Collectors, Payers and other character symbols can interact to increase the total bonus payout.

Later Money Train releases introduce additional variations and more complex combinations.

This creates opportunities for the bonus to develop over multiple respins.

However, the appearance of a particular special symbol does not guarantee a large payout.

Cascading Wins

Cascading mechanics appear in several Relax Gaming games, including Temple Tumble Megaways.

When a qualifying win occurs, the winning symbols disappear.

New symbols enter the grid, potentially creating another winning combination.

This process can continue while further wins occur.

Some games combine cascades with multipliers or other enhancements, but the exact rules differ between releases.

Bonus Buy Features

Selected Relax Gaming slots offer direct purchases of bonus rounds.

These features allow players to access certain bonuses without waiting for a natural trigger.

However, Bonus Buy availability depends on the game and jurisdiction.

Purchased bonuses can return less than their purchase price and may involve substantially higher costs than ordinary spins.

Multipliers and Respins

Multipliers and respins are common features throughout Relax Gaming’s catalogue.

Multipliers can increase the value of qualifying wins, while respins provide additional opportunities for special symbols to interact.

Some games also include persistent symbols or values that remain active throughout a bonus.

The combination of these mechanics is particularly important in the Money Train series.

Dream Drop Jackpots

Dream Drop is Relax Gaming’s progressive jackpot network, launched in 2022.

Unlike a fixed maximum payout attached to a single slot, progressive jackpots can grow through qualifying play across participating games.

Dream Drop operates as a network product, meaning that the jackpot system can be incorporated into different titles.

The network originally launched with five progressive jackpot tiers and has subsequently expanded to include a sixth jackpot category with daily awards.

The current structure includes several jackpot levels, including Major and Mega prizes.

Relax Gaming has promoted a Mega Jackpot worth up to €2 million under the current product structure.

However, jackpot values, eligibility and availability depend on the relevant game and jurisdiction.

It is important to distinguish a slot’s ordinary maximum payout from a separate progressive jackpot.

For example, a Dream Drop title may have a published maximum payout for its regular gameplay while also offering access to network jackpots.

These are different types of prizes and should not be treated as interchangeable.

Relax Gaming RTP and Volatility

Relax Gaming does not have one universal RTP or volatility level across its entire portfolio.

Each slot has its own mathematical model.

Some titles offer relatively high theoretical RTP values, while others are available with lower configurations.

According to AboutSlots’ reviewed selection, Relax Gaming has an average RTP of approximately 95.7%.

However, this figure represents the games included in that database rather than a guaranteed average for every title developed by the company.

Book of 99 is an example of a game with a published RTP of 99.00%.

Other releases have different RTP values depending on their design and available configurations.

Volatility also varies.

The Money Train series is particularly associated with high-volatility gameplay, where substantial advertised payouts are possible but large outcomes are rare.

Other Relax Gaming releases use different mathematical profiles.

Players should therefore assess RTP and volatility at the individual game level rather than relying exclusively on the provider’s overall reputation.

Maximum Wins

Relax Gaming has developed several slots with unusually high advertised maximum payouts.

Money Train 3 offers a maximum win of 100,000×.

Money Train 4 increased this to 150,000×.

Money Train 5 introduced two modes with different maximum payouts: 50,000× in Standard Mode and 100,000× in Ultra Mode.

These figures demonstrate the developer’s focus on high-potential bonus mechanics.

However, maximum wins represent theoretical payout limits rather than expected outcomes.

The probability of reaching a maximum payout can be extremely low.

Players should never assume that a high maximum win makes a game more likely to produce a profitable session.

Mobile Gaming Experience

Relax Gaming develops its casino games for modern mobile and desktop platforms.

Its slots are generally compatible with supported smartphones, tablets and desktop browsers.

The interface adapts to different screen sizes, while bonus animations and special symbol effects remain part of the experience.

Games such as Money Train can contain numerous special symbols and multiplier values, making a clear interface particularly important.

The developer’s experience with casino technology and content delivery supports its cross-platform approach.

However, performance may vary depending on the device, browser and casino operator.

The mathematical rules remain the same when the same game configuration is used.

Silver Bullet and Powered By Relax

One of Relax Gaming’s most distinctive characteristics is its role as a content aggregator.

The company does not exclusively distribute games developed by its own studios.

It also works with independent developers through two main partnership programmes.

Silver Bullet

Silver Bullet is designed to support selected independent game studios.

The programme provides commercial representation and access to Relax Gaming’s distribution network.

This can help smaller developers reach casino operators without establishing every commercial relationship independently.

Studios associated with the programme include developers such as Print Studios, Peter & Sons and 4ThePlayer.

However, games created by these studios should not automatically be described as proprietary Relax Gaming titles.

They remain products of their respective developers.

Powered By Relax

Powered By Relax provides distribution and technical integration for independent studios that retain their own commercial relationships.

This allows casino operators to access additional content through Relax Gaming’s platform.

The distinction between the two programmes is primarily commercial and operational.

For players, the important point is that Relax Gaming can appear as a distributor even when another studio developed the game.

This makes accurate developer attribution important when reviewing individual slots.

Licensing and Regulation

Relax Gaming operates within several regulated gambling markets.

The company holds relevant licences or approvals in multiple jurisdictions, including Great Britain and Malta.

Its UK operations are regulated by the UK Gambling Commission.

Relax Gaming also supports other regulated markets through its licensing and distribution arrangements.

However, a supplier’s licence should not be confused with a casino operator’s licence.

Players should verify that their chosen casino is authorised to operate in their jurisdiction.

They should also check whether the specific game and its features are permitted locally.

For example, Bonus Buy features may be restricted in certain markets even when the underlying slot is available.

Slotinia’s Verdict on Relax Gaming

Relax Gaming has established itself as one of the most influential developers and content suppliers in modern online slots.

Its strongest achievement is the combination of a recognisable proprietary game portfolio with an extensive distribution platform.

The Money Train series demonstrates the company’s ability to develop and refine complex bonus mechanics over multiple releases.

Temple Tumble Megaways highlights a different strength, combining accessible cascading gameplay with a recognisable theme.

The Dream Drop network adds another dimension through progressive jackpots available across participating titles.

Beyond its own games, Relax Gaming supports independent developers through Silver Bullet and Powered By Relax.

This makes the company important not only as a game creator but also as a distribution partner within the wider iGaming industry.

However, not every game distributed through Relax Gaming is developed by Relax Gaming itself.

The distinction matters when evaluating individual titles.

The developer is also strongly associated with high-volatility slots, particularly within the Money Train franchise.

These games may appeal to players interested in complex bonus mechanics, but their substantial maximum payouts should not be mistaken for likely outcomes.

Overall, Relax Gaming stands out through its technical expertise, influential slot franchises and extensive casino game ecosystem.

Its strongest qualities are the Money Train series, its variety of bonus mechanics, Dream Drop Jackpots and the ability to bring independent studios to a wider audience.

Responsible Gambling

Relax Gaming develops games of chance involving financial risk.

RTP, volatility, bonus features and maximum advertised payouts do not guarantee any particular outcome.

High-volatility games can produce extended periods of limited returns, while Bonus Buy features may involve substantial costs.

Players should verify the rules and RTP of each game, establish a budget before playing and avoid chasing losses.

Gambling should always be treated as entertainment rather than a source of income.
