Nitropolis 3: a grid inside the grid

Nitropolis 3 begins on six reels and four rows, but the field can expand to eight rows. Nitro Reels put smaller reels inside that field: a small Nitro Reel occupies two positions and can hold up to twelve single symbols, while a large one occupies six positions and can contain six double symbols. The expanded screenshot shows why counting only the large outer columns misses part of the game.

Avalanches, Both Ways and Redrop

Avalanches remove winning symbols and bring replacements into the gaps. Green features can affect the same reel and neighbouring reels, while Both Ways adds right-to-left evaluation. The Redrop feature keeps bonus symbols and Nitro Reels in place and respins the Nitro Reels. These features alter how a sequence develops, rather than all acting as simple payout multipliers.

Free spins and Super Bonus

Three bonus symbols trigger free spins, during which Nitro Reels stay in position. The Super Bonus begins with the eight-row field and Both Ways active. The studio screenshot illustrates a bonus entry, not a typical payout. Compare those starting conditions with the smaller base game before treating the two modes as interchangeable.

Nitropolis 3: the Super Bonus entry shown in the studio replay begins with eight free spins. The displayed result is illustrative.
