Nitropolis Bonus Features

Free Spins

3 scatters = 10 free spins

4 scatters = 15 free spins

5 scatters = 20 free spins

6 scatters = 25 free spins

For this feature, a random symbol will be turned into a Scatter-paying symbol. This means that it doesn't need to appear as part of a payline to win; it just needs to appear more than three times anywhere on the reels. It is also possible to retrigger the free spins feature.

Nitro Reels

The innovative Nitro Reels is an excellent random feature that sees sets of two rows turn into a 'Nitro Reel', packed with up to 12 identical symbols and causing all sorts of extra wins! It's this Nitro Reels feature that causes the paylines to rise from the basic 4096 up to a maximum of 85,115,840, which is quite possibly the highest payline number in the pokie world. A Nitro Reel that appears in a respin or free spins may be upgraded to a higher-paying symbol. If the Nitro Reel doesn’t cause a win, it can randomly cause a second chance respin.


Any symbols or Nitro Reels that form part of a win automatically respin to land more symbols in their places. The respin feature continues until no new wins are formed.
