Nitropolis 4 slot by Elk Studios is simply a variation of Nitropolis 3 slot which was released a year before, as was that of Nitropolis 2 slot and naturally prior to that the original Nitropolis slot. It retains therefore the dystopian urban theme in a cartoon form with block symbols, splitting symbols and modifier tiles. The game has 6-of-a-kind pays of 3x down to 0.3x bet with Wilds, Nitro Boost modifiers and initially 4096-ways to win with the 4 rows of each reel. There are replacement symbols via tumbles and the reels can expand up to 8-rows high or 262144-ways. The Nitro reel system is in play and these cover 2-rows on a column and split into 4-12 paying symbols, Big Nitro Reels are 2-rows wide and 3-rows high and offer 2-6 2x2 symbols. You can also see random colossal 3x3 symbols.
Modifiers of Nitropolis 4 slot
The Nitro multiplier 2-row stacked tile can drop which offers a 2,4,6,8,10 or 12x multiplier, multiplicative if more than one counts in a way win. Nitro Boosts are Redrop which keeps the special symbols and replaces the rest, Both Ways which means the spin pays right-to-left too, Max Rows which expands the grid to 6x6 and Garbage Collect which removes instances of a low-value tile. The second four are Nitro Appear which puts a Nitro split symbol multiplier somewhere, Nitro Wild which transforms any Nitro Reel to Wild, Nitro Upgrade which upgrades an existing Nitro Reel and adds more symbols to it (max 12x) and finally Nitro Match which changes the present Nitro Reel symbol to match one in view.
You need 3 bonus scatters for 8 free games with +4 for each one over, maximum 20. If triggering with at least one Super Bonus (which can only appear in Nitro Reels) symbol then from the start you play maximum 8-rows and both-way pays. Otherwise, you retain 'safety levels' of one row added for each win attained to hopefully reach the 8-rows as quick as possible. You can retrigger the round.
Nitropolis 4 slot has a RTP of only 94.00% and is very high in volatility terms. The maximum win is capped at 50,000x bet here and there's no bonus buys.
