Numero Uno Slot, Details & Wager Limits

Reels/Paylines: 5 reels + 243 ways to win

Stakes Range: 20p to £120 per spin

Max Win: 2,113.2 x stake per spin

RTP: 95.22%

Played on 5 reels and 3 rows, this Numero Uno slot comes with 243 ways to win. Wins start from reel 1 on the far left and pay left to right only on adjacent reels.

Stakes range from 20p up to £120 per spin. Use the coin icon below the spin button to the right of the reels to change your total bet. Quick spins and autoplay are also possible in most territories outside the UK.

The Numero Uno RTP is 95.22%, which is lower than a lot of other slots around and below the 96% average for an online slot. I understand lower RTP percentages if the max win is high, but I’m a little disappointed to see it below average considering it’s a highly volatile slot and the max win is quite low.

The hit frequency is 31.52%, which is healthy. This means that just under a 3rd of all spins on average will result in a winner.

The maximum win is 2,113.2 x your stake, which is a lot lower than many other slots on the market today. The Free spins feature will be your best chance of landing it due to the number of free spins you could get along with numerous multipliers. More on the bonus features further down.

Theme – wrestling with a twist

Theme: Wrestling

High Value Symbol: Scatter

Compatibility: Mobile, Tablet, Desktop


The theme in the Numero Uno slot game is all about wrestling and the old Mexican art of Lucha Libre. But this time it’s not humans wrestling, it’s dogs as Microgaming put a twist on the theme to make it more appealing. Has it worked? I’m not so sure, to be honest.

On reels, you’ve got A-J royals as the low-paying symbols. The higher paying ones are numerous animals, made up of a chicken and 4 different dogs. The Red Masked Dog is the most rewarding symbol of them all, but the Scatter in fact pays the most – awarding 4.8, 50 or 250 x your stake for 3, 4 or 5 in combination as well as triggering the Free Spins feature.

The game’s Wild is an eagle symbol, and there are more than 40 of them stacked on reels, 3, 4 and 5 to boost your wins. The Wild can substitute for all symbols except Scatter.

Numero Uno Mobile


The Numero Uno slot game can be played on desktop, mobile and tablet devices as standard. Microgaming ensures that its games are all multi-platform as they are produced using HTML5 technology. With the 5×3 setup, it plays really well on smaller screens.

Numero Uno Bonus Features

There are 3 main bonus features in the Numero Uno slot game – Rolling Reels, Wild Showdown, and a Free Spins feature that can multiply all wins up to 10x. Let’s explain how they all work for you to get a better understanding of the slot as a whole.

Rolling Reels

Rolling Reels will trigger on every win, with symbols that contribute to a win exploding when they land. New symbols then drop into the empty spaces and can complete additional wins. Rolling Reels are active in both the base game and the Free Spins feature.

Wild Showdown feature

This feature is triggered randomly in the Numero Uno slot game and produces a guaranteed win. Numero Uno faces off with an opponent, turning reel 2, 3 or 4 Wild.

During Wild Showdown, Rolling Reels are not active

Free Spins feature


Land 3 or more Scatters in the base game to trigger the Free Spins feature. Here’s how many free spins you could get depending on how many Scatters you land in the base game:

Scatters Free Spins Awarded
3 15
4 20
5 25

Consecutive Rolling Reels wins here will unlock larger rewards on the multiplier trail that you can see above the reels. It offers multipliers of 2x, 3x, 4x, 5x and 10x.

The Free Spins feature cannot be retriggered

With a fun soundtrack and great visuals, the Numero Uno slot is let down by high volatility and low max win potential. It’s certainly a colourful slot, and going against the grain with animals instead of humans was a bold move. It will appeal to some for sure, but I’m not hopeful that it will become one of the better releases.

The bonus features are pretty good, but there are many better alternatives available that come with more features and bigger max win potential. At least the hit frequency is generous at 31.52%. Overall, it’s not blown me away by any means, but if you like your Mexican wrestling and maybe even a fan of dogs, this slot will probably be worth giving a go.

Want more Mexican madness? Dia Del Mariachi Megaways has a ton of bonus features. But if it’s bigger win potential you want, ReelPlay’s Money Mariachi Infinity Reels comes with 50,000 x max wins.

If it’s more wrestling action you’re after, you won’t get much better than WWE Legends: Link & Win from Microgaming. As well as some solid bonus features and 4 different jackpots, it comes with max wins of 25,000 x your stake, which is a lot higher than this slot.

  • 2,113.2 x max wins
  • 31.52% hit frequency
  • Fun theme
  • Highly volatile
  • Free Spins cannot be retriggered
