Use Code: OLYMPUS400

At Zero Spiel, we’re always watching for casino promotions that actually pair well with new slot releases, and CasinoMax has just rolled out one of the more interesting RTG offers we’ve seen recently.

Players can now claim a massive:

400% Bonus + 40 Free Spins on Olympus Thunderhold

Bonus Code: OLYMPUS400

• 400% Deposit Bonus 40 Free Spins on Olympus Thunderhold *T&C Apply Min Deposit: $10 Code: OLYMPUS400 Claim Bonus

The promotion arrives alongside the release of Olympus Thunderhold, RTG’s brand-new Greek mythology slot packed with cascading wins, multiplier mechanics, and Zeus-powered Free Games.

For players looking to test the game with extra bankroll support and bonus spins, this promotion gives a strong starting point.

Olympus Thunderhold – Zeus-Powered Slot Action

Olympus Thunderhold is one of RTG’s newest mythology-themed releases and features:

• 6 reels and 5 rows
• Pays Any mechanics
• Cascading Wins
• Wrath Multipliers up to 100x
• Free Games with retriggers
• Buy Feature option
• Medium volatility gameplay

The slot’s standout feature is the Multiplier Symbol system during Free Games. Multipliers ranging from 2x to 100x stay active during cascades and combine together at the end of winning sequences.

The result is a highly energetic bonus system built around chain reactions and stacked multipliers.

The game officially launches on May 13, 2026.

Why This Bonus Stands Out

Unlike many slot launch promotions, CasinoMax keeps this offer fairly straightforward.

What We Like

✔ Large 400% bonus percentage
✔ 40 Free Spins on the new release
✔ Plinko included alongside slots
✔ Straightforward redemption process
✔ Works well for medium bankroll sessions
✔ Pairs directly with Olympus Thunderhold gameplay

The 40 spins provide a solid opportunity to experience the game’s multiplier mechanics without immediately risking a full deposit balance.

• Minimum deposit starts at $35

As always, we recommend reading the full casino terms before activating any promotion.

Zero Spiel Final Thoughts

The CasinoMax Olympus Thunderhold promotion does a good job pairing a strong launch bonus with a feature-heavy new RTG slot.

Between:

• 400% bonus value
• 40 Free Spins
• Zeus multiplier mechanics
• Cascading wins
• Medium volatility gameplay

there’s enough here to make the launch feel worthwhile for both mythology slot fans and bonus hunters.

If you enjoy modern RTG releases with energetic reel mechanics and multiplier-driven Free Games, Olympus Thunderhold is definitely worth checking out.
