Santa’s Stack Dream Drop is a cluster slot with a 5-symbol minimum for clusters. The wild symbol can replace any symbol, enhancing winning chances. The Secret Santa Re-Spin feature activates with a wild in a winning cluster, turning the cluster into mystery symbols and awarding a re-spin. This can continue as long as adjacent wins occur. Free spins are triggered with 3+ Bonus symbols, where each spin starts with guaranteed wilds, increasing in number per spin. Free spins can also offer extra spins, multipliers, or both. Players can win up to 20,000x their bet. Additionally, the slot features a Dream Drop Bonus with 5 Jackpots, triggered randomly before a normal spin.
