Golden Fish Tank 2 Gigablox uses six reels with four to six rows and a changing line layout. Its large Gigablox symbols are the sequel's main addition to the aquarium theme. Free spins retain a Pick and Click stage for selecting special features, while a bonus chest adds another event. The original Golden Fish Tank's five-reel, twenty-line specification therefore should not be copied into this sequel's instructions.

To compare related slots formats, read the rules of Golden Fish Tank Party and 4 Fantastic Vikings Go Ice Fishing.

The library also explains the difference between lines, ways and clusters to help put these mechanics in context.
