The Nitropolis series is a lineup with a loyal fan base even among ELK Studios slots. The oil rig setting adds a fresh touch to the series.

Which features appear in the Nitro Booster?

The two screens above the reels trigger Nitro Booster features at random. There are 8 features: Max Rows, Garbage Collect, Nitro Reels, Nitro Wilds, Nitro Upgrade, Nitro Match, Re-drop, and Both Ways. Depending on which feature turns on, the same spin can lead to a completely different result. Part of the fun is watching which of the two screens will light up.

How are Nitro multipliers calculated?

Nitro multipliers apply a multiplier to every win on the screen. It doesn’t end there: when several Nitro multipliers are on screen at once, they multiply each other. The moment two or three multipliers overlap on one screen is when this game produces its biggest wins. Because multipliers are multiplied rather than added, the result differs a lot even with the same count, and this is considered the game’s biggest appeal.

How do the Bonus and Super Bonus differ?

Landing 3 or more bonus symbols starts the free spins bonus, and during free spins all Nitro Reels are locked in place. If bonus symbols and super bonus symbols appear together, the Super Bonus opens with Max Rows and Both Ways already active. In the Super Bonus, the screen is expanded to max rows from the start, so together with the locked Nitro Reels it sets up good conditions for chasing a big win.

What should I check first in the demo?

RTP is 94.00%, official volatility is 8 out of 10, hit frequency is 18.1%, and the bet range is €0.20 to €50. X-iter has 5 options, from a 2x bet up to a 500x Super Bonus with max rows and both directions active. In the demo, first look at how often two or more Nitro multipliers overlap. Also keep an eye on how often booster features appear.
