Win on a Nitro Reel and it respins at the next Avalanche, while each cascade adds a row until the grid reaches 8. In the Free Spins those Nitro Reels stick for the whole round, and the grid's starting height can rise but never drops back. My two rounds, opened by 3 and then 4 Zeppelins, never…

Zeppelins, Dogs and Dirty Dawgs
The basics at work here are these. You get 6 reels, 4 rows and 4,096 ways that pays from the left, and the bet range begins at 0.20 and climbs all the way up to 50 Eur per spin, and it's delivered to the casinos with the RTP of 95.00%. I played 470 spins at a 6.00 stake for a 98.6% session return, and my 2 Free Spins rounds paid 1,398.00 of the 2,781.60 won.
On the reels, Dogs, Cats, Pugs and Rats sit at the top of the paytable. Below them come Dirty Dawgs, Gritty Kitty, Pug Thugs and Rogue Rats, none of which pays more than 1x the stake for 6 of a kind. You'll also run across A to J, and the Dogs are the highest paying, handing you 5 times your stake for 6 of a kind, while the wild can land as a 1x1, 2x2, 3x3 and 4x4 wild. Three, four, five or six Zeppelin Scatters anywhere on the grid start 8, 12, 16 or 20 Free Spins, all Nitro Reels stay sticky for the whole round, and 3 or more Scatters during it retrigger the bonus.
Final Minty Score: Two Free Spins rounds, on spins 290 and 448, paid 1,398.00, half of everything the 470 spins returned, and neither retriggered.
How Nitropolis 3 Grows Its Grid
Nitropolis 3 is a cascading slot, and it's all about the Avalanches. They attach a row to the matrix. A Nitro Reel covers 2 positions and holds 4 to 12 matching 1x1 symbols, and when it is part of a win, it respins at the incoming Avalanche. The winning symbols fall away when they land, fresh ones drop in and a row is attached while the matrix stays enlarged. In the Free Spins the Safety Level takes over, raising the grid's starting height by at most 1 row per spin and never letting it shrink back during the round.
Now, if another win lands, it too falls away. My biggest win outside the Free Spins came on the last spin, number 470, when an Avalanche with Nitro Reels on a grid grown to 8 rows paid 463.80, or 77.3x the stake. Another row is attached, and in total you can hold 8 rows.
