Wild Scatters
3 Treasure Chests, appearing on the 1st, 3rd, and 5th reel, trigger re-triggerable Free Spins. During Free Spins, these Chests become Wild and substitute for all symbols except Blackbeard.
During Free Spins the Eye Drone transforms into 3 Targets that double or triple your wins or give you an extra Free Spin, and their multipliers can be combined!
