The round commences with four rows open and four rows locked.

There are two types of Thunderball symbols in Link & Win:
All triggering Thunderball symbols will lock in place at the start of the round and remain until the end.

At the end of the feature, every cash and jackpot prize on the unlocked rows will be awarded.
