Best Relax Gaming Slots: Top Games & Demos

Who is Relax Gaming?

Relax Gaming is a B2B slot provider founded in 2010. It runs in-house game studios alongside the Silver Bullet aggregation platform, which distributes partner-studio titles to licensed operators. In practice, that means Relax originals and a wide partner roster can turn up in the same lobby as other casino games.

Signature Mechanics and Unique Features

Relax's lineup keeps returning to a few signature systems.

• Dream Drop Jackpots: a shared progressive jackpot engine that plugs into select titles, including Money Train Origins Dream Drop and Temple Tumble 2 Dream Drop.
• High-volatility maths models: RTP (Return to Player) is the percentage of wagered money a slot pays back over time, and volatility is how often and how big those payouts land. Most core Relax Gaming titles rate high, so expect bigger wins that arrive less often.
• Buy bonus options: some titles let you pay a one-off multiple of your stake to skip straight to the feature round. It's banned in the UK and unavailable in some other markets, and a single buy can eat a big chunk of a session budget, so set a loss limit before you try one. Our full list of bonus buy slots covers a wider range of titles.

Top-Rated Relax Gaming Titles to Play Right Now

The titles below have the highest multiplier ceilings and RTPs among the games covered here.

Money Train Series: High Volatility, Big Ceilings

Money Train made its name with the Money Cart bonus, a hold-and-win round stacked with multiplier symbols. Money Train 2 carries a 96.40% RTP and a 50,000x max win. Money Train 3 doubles that ceiling to 100,000x, at a slightly lower 96.10% RTP.

Money Train 4 keeps the same 96.10% RTP. The Bandit hit 18,801x on it in our week 26 2026 Big Wins recap, the second-biggest win of that week. That's the series at its best. It runs high volatility, and most sessions finish far short of the max win. Our guide on how to win at online slots explains how volatility and bankrolls work, though nothing in it changes the odds.

Temple Tumble Megaways: Grid-Based Action

Temple Tumble drops you straight into a cascading, block-clearing 6x6 grid with up to 46,656 ways to win. Megaways drives the reel engine, changing the number of symbols and win ways on every spin. Winning symbols clear and new ones drop in, chaining wins within a single spin.

The bonus round can award multipliers, extra spins or both. RTP is 96.25%, though some casinos run a lower 94.00% version, and volatility is high. At 7,767x, it has the lowest max win in the table below. You can browse more of the format on our megaways slots hub.

Relax Gaming Slots: Key RTP and Volatility Insights

All five titles below run high volatility, and two of them, Book of 99 and Marching Legions, sit far above the usual 96% RTP range. The other three land around 96%.

Slot Game	RTP%	Volatility Level	Max Win Potential
Book of 99	99.00%	High	12,075x
Marching Legions	98.12%	High	10,000x
Money Train 3	96.10%	High	100,000x
Iron Bank	96.20%	High	49,998x
Temple Tumble Megaways	96.25%	High	7,767x

Book of 99 has the highest RTP of the five, and 99.00% is far above the usual 96% range in online slots. Higher RTP doesn't mean bigger wins, though: Money Train 3 returns 96.10% and hits 100,000x, while Book of 99 tops out at 12,075x. Iron Bank lists 49,998x at 96.20%, and its sequel, Iron Bank 2, landed 16,375x for LetsGiveItASpin in our week 21 2026 Big Wins recap. RTP varies by casino, so check the in-game info panel before you play.

Where to Play Relax Gaming Online Safely

Run through these checks before you deposit anywhere.

• Check the licence first. Look for MGA or UKGC registration in the casino's footer before you sign up.
• Confirm fair-play standards. Licensed casinos must run their games on independently tested RNGs (Random Number Generators).
• Read Online casino reviews written by real players and streamers, not just marketing copy.
• Compare cashout speed. Fast, fee-free withdrawals are a trust signal. Slow or blocked payouts are a red flag.
• Browse the latest online casinos to find new sites, and check which Relax Gaming titles each one offers.
• Check Best online casino payment methods before you register to make sure your preferred option is supported.

Gambling is entertainment, not a way to make money. Every Relax Gaming slot has real volatility, so wins and losses are both possible in any session. Set a budget before you play, and contact BeGambleAware or your local support service if it stops being fun. 18+.

Conclusion

Relax Gaming's numbers pull in two directions. Money Train 3 hits 100,000x and Book of 99 returns 99.00%, but all five slots in our table are high volatility, so long dry spells between big wins are part of the territory. Set a budget before you load any of them.

Silver Bullet also brings partner-studio games to casinos alongside Relax's own releases. The free demos at the top of this page are the quickest way to try the studio, and our new online slots hub tracks the latest releases across every studio.
