How to play Nitropolis
Welcome to Nitropolis, an exciting 6-reel, 4-row slot game with up to 85,155,840 ways to win. The game can be played with a minimum bet of 0.2 and a maximum bet of 100, allowing you to customize your bets according to your budget.
All bets are made in coins, and winning combinations pay out from the leftmost reel to the right on consecutive reels. Only the highest win per active payline is paid out, and all winnings are paid out according to the paytable. Nitropolis is played in two modes: Normal mode and Bonus mode with free spins.
During gameplay, each win triggers a respin feature, and each symbol and Nitro Reel that is part of a win respins individually. The Nitro Reels feature unique Nitro Reels that can cover two symbol places and range in size from 4 to 12, with each size containing a different number of identical 1×1 symbol instances. Nitro Reels can randomly increase in size during a respin or between free spins, and one or more Nitro Reels can randomly respin at the end of a spin when there are no additional wins.
The game’s wild symbol substitutes for any symbol except the bonus symbol, and in free spins, wilds will substitute for the scatter paying symbol in a scatter win. One paying symbol is randomly selected for scatter wins during the Bonus mode, and all Nitro Reels lock in place for the remaining free spins. If you land three or more bonus symbols during Bonus mode, you can retrigger additional free spins, with up to three scatter paying symbols available.
The theoretical payout (RTP) in Nitropolis is 96.1%, and the game has a maximum win of TBB the placed bet. So, come and join the fun! Spin the reels and see what kind of excitement awaits you in Nitropolis.
