Bonus Verdict
Boost your first deposit with a 125% match of up to €500 and 125 free spins on Book of the Fallen with this VulkanSpiele Casino welcome bonus. A standard €10 deposit is required, with 40x wagering on the match bonus and 30x on the spin winnings. The 3x deposit max cashout limits withdrawal potential, but this bonus still provides solid value for extending your gameplay.
Enter the bonus code KOSMO1 before depositing to claim the bonus.
Free spins are only available on slots Fire Joker, Elvis Frog in Vegas, or Aztec Magic Deluxe
Bonus Verdict
The bonus offered by Kosmonaut Casino is a fruitful offer. But the 40x wagering on both the bonus and free spins can be tough. You only have 3 days to meet the requirements, so it’s a bit rushed if you like taking your time. It’s a solid option if you’re into higher stakes, but if you’re a casual player, the conditions might be too strict.

While her PR degree taught her how casinos market themselves, her work at CasinoAlpha focuses on what they often hide: ethical gambling practices and self-exclusion tools that truly protect players.
