Reviews

Thunderbolt Casino has been my go-to site for the past few months. The welcome bonus was incredibly generous, and the variety of slot games is outstanding. Highly recommended for any NZ player!

Great selection of games and smooth gameplay. The withdrawal process took about 2 days, which is reasonable. Customer support was helpful when I had questions about the terms.

I've tried several online casinos, but Thunderbolt Casino stands out with its user-friendly interface and fair payouts. The mobile version works perfectly on my phone.

The site is decent overall, but I found the bonus wagering requirements a bit high compared to competitors. Games are good though, and I managed to cash out my winnings without issues.

Excellent customer service team! I had an issue with a deposit and they resolved it within hours. The game variety is fantastic, especially their progressive jackpot slots.

Okay experience overall. The welcome bonus is nice, but some games felt a bit slow to load. Payment options could be better for NZ players.
