Thunderbolt Casino pairs the arrival of Crimson Castle with a new-player offer: a 300% deposit bonus up to R8,000 plus 100 FREE Spins on the featured slot. Coupon CRIMSON300 activates the promotion, with a R25 minimum deposit and an expiry of 31 October 2026. The 300% figure describes the deposit bonus; the R8,000 figure caps that bonus amount.
Crimson Castle uses a 5×3 reel layout and brings together a Hold & Spin feature, multipliers, Golden Coins and Moon Symbols. Its advertised prizes include Mini, Minor and Major jackpots. For the offer, the newsletter lists wagering as 30x (deposit + bonus) + 20x the bonus and limits cashout to 20x your deposit. Review how the casino applies those wagering components before claiming.
