Bonus Verdict
BaxterBet Casino’s first deposit offer is available for a high min. deposit of €20. However, we appreciate that the wagering is standard 35x WR and just on the bonus, and you can cash out €500. The spins have similar 35x wagering, with €50 withdrawal limits.

The max cashout is 5x your deposit
Bonus Verdict
This 1st deposit offer comes with an accessible €10 min deposit and decent 100% match value that our team recommends, but the 40x WRs of 40x the bonus and 40x winnings on free spins are considerable. Also, the max cashout limit is restricted to 5x your deposit.

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.
