How to play Numero Uno mobile slot

Who is number one? The Numero Uno slot answers that question by giving you multiple wild reels, avalanching reels, and a top win of over 2,100x your bet.

With some sweet Mexican arias playing in the background, you might expect big rumbles from these wrestlers. You won’t expect the barks and bites, as the four main contenders are dogs and the highest paying symbols on the reels. This is followed by a chicken referee and Ace to J.

Numero Uno by Microgaming is a 5×3 reel 243 ways to win mobile and online slot machine with tumbling reels, stacked wilds, and scatter that trigger the free spin bonus where you can get up to 10x multiplier on multiple wins in a row. It’s a mid-volatility slot game with an RTP of 95.22% and a top win of 2,113x your bet.

In many ways, it resembles the likes of the Basketball Star slot and the Hockey Hero slot – simple, easy-to-understand mechanics that anyone who is getting introduced to casino slots online can just pick up and play easily, with a nice wide betting range of 0.20 to 120 a spin.

Where are the big wins of the Numero Uno slot?

In the base game, you have two wild features. The first is the stacked wilds that only appear on reels 3, 4, and 5. They show up often and are, by far, the most frequent feature on the reels.

What’s really exciting is that the stacks keep on going. So when they are part of a win, they explode as you would expect from an avalanching win. But more often than not, more wilds will drop down, covering the reel and giving you plenty of chances for more wins.

The second wild feature is the Wild Showdown, where our number one dogfighter, Numero Uno himself, will flash onto the screen randomly, giving you a wild reel on reels 1, 2 or 3.

Combined, and you get… maybe a top 500x your bet wins if you are lucky. Till you hit the scatters.

The Numero Uno slot free spins

3 scatters will trigger a minimum of 15 free spins, and much like in the Gonzos Quest slot, every win will increase the multiplier.

The problem is that, unlike other avalanching slots with multipliers, the first win of the Numero Uno mobile slot is 1x. It’s only on the second rolling reel win that you get a 2x multiplier, and on the 6th win that you get a 10x multiplier.

If you can get that roll of wins, it’s exciting in a way that few other Microgaming slots can beat, especially if those stacked wilds come into play.

It’s not easy, and without a x4, 5x, or 10x multiplier, the paytable can feel weak. But as long as you are realistic about what this rumble can offer, the Numero Uno slot game will provide you with plenty of fun spins at your favourite mobile casinos online.

In-game bonus features

Stacked Symbols: More than 40 wild symbols are added to the reels, coming as stacks on reels 3, 4, and 5. These wilds can substitute for all symbols except the bonus scatters.

Wild Showdown: Numero Uno can show up and turn reels 2, 3, or 4 wild. This is triggered completely randomly.

Rolling Reels: On a win, the winning symbols explode, and the rest of the symbols tumble down. You then get new symbols falling down to replace the empty spaces, giving you another chance to win. This continues until no more wins can be found.

Scatters and Free Spins: 3, 4, or 5 scatter symbols trigger 15, 20, or 25 free spins, respectively. Only this time, when you get a win, the multiplier goes up.

Numero Uno Review Conclusion

With a cute slot theme and some decent game mechanics, this Numero Uno game does everything right. You have avalanching reels, stacked wilds, and some added multipliers in the base game.

The mid volatility allows for some steady win, as long as you accept that the top win of 2113x your bet is only available in the free spins, and even then with a 10x multiplier. If you win even half the top win, it's a good round.

This is a very pleasant slot. Will it make a lasting impression on us years into the future? No. Will we smile if we come across it at one of our favourite Microgaming casinos and take a few spins? Absolutely.
