Nitropolis 3 Slot Free Play
How To Play It
The wagers of Nitropolis 3 start from the standard $0.20, and go only up to $50 from there (most ELK slots go up to $100).
Its game area offers 6 reels of 4 symbols each, with a total of 4096 ways to win. Thanks to the Nitro Reels, double-stacked symbols which count as up to 12 matching symbols, the reels can expand in a major way. More on that below.
Special Features
The Nitro Reel is a symbol which lands on two positions (it’s stacked), but which contains between 4 and 12 regular symbols of the same type. Rather than count as 2 symbols, the Nitro Reel count as up to 12, so this increases the number of potential ways to win.
Additionally, this game also uses big Nitro Reels, which give you up to 6 symbols of 2×2 positions (while they occupy 6 symbol positions at most).
Big symbols are larger than the usual ones, even up to 4×4 positions being occupied by one of these.
After you’ve formed any winning combination, an Avalanche will always follow. This makes all regular symbols explode, which allows new ones to drop down. At the same time, the game area expands with one extra row at the top. Up to 8 rows can be available eventually.
A Toxic Sign Wild will be present in the game, ready to be used as a substitute whenever it is appropriate. It’s a replacement for regular symbols only, and it can come in both regular and big versions.
Several random symbols/modifiers can show up. Some may bring you wins both ways, others will remove all regular symbols, upgrade Nitro Reels, or transform them into other types. You can also get Nitro Wilds this way.
The main feature is going to involve 8 to 20 free games, triggered through 3 to 6 Zeppelin scatter symbols. A big advantage is that the Nitro Reels are sticky in this mode. That, plus once the reels have expanded to a certain size, they can’t go back to a lower one.
If a Super Bonus symbol contributed at the start, the game area is at its maximum size and the combinations will form both ways.
Maximum Payouts
A top jackpot of 50,000x the stake is the promise here, which sounds amazing. While the volatility will be high, it’s the 95% RTP that bothers me most.
Summary
Nitropolis 3 is a pretty good game overall, especially if the series is already known to you. The 95% RTP is the only major downside I see, otherwise it offers enough unique features and mechanics to be fun.
