My Opinion about 333 Casino Bonuses and Promotions
At the time of my registration, the operator offered a choice of four types of welcome bonuses for new players. I was even confused at first, but then, I rejected the option with a higher wager of x40. I settled on a bonus for the first 3 deposits with a wager of x30. It gave 150 free spins and an increase in the deposit up to £500. The bonus was valid for 28 days, so this time was enough for me to wager.
I also liked the selection of games offered for this type of bonus. The operator included slots with high RTP: Starburst with 96.1%, Aloha! Cluster Pays with 96.42%, and Finn and the Swirly Spin with 96.62%.
Overall, I was happy with my choice. After wagering the welcome bonus, I got involved in the prize draw, which did not even require a minimum bet. Based on my impressions, I can say that I liked the bonus policy of 333 Casino. However, it would be nice if the casino gave the opportunity to use a promo code to increase the bonus. I hope that such types of promotions are still to come.
