xNudge slots explained

What xNudge slots are

An xNudge slot is an online slot from Nolimit City that contains the studio’s xNudge wild. It is one of the studio’s branded “x” mechanics, listed alongside xWays, xSplit and xBomb on our Nolimit City provider page. The idea borrows from two older features at once: the stacked wild, which fills several positions on one reel, and the nudge, the button on a British pub machine that moves a reel one step.

On its own, a stacked wild that lands with only its bottom tile showing does little. An xNudge wild instead slides into view one row at a time until the whole reel is wild, and each step it takes adds one to a multiplier attached to it. A wild that needed three nudges carries a bigger multiplier than one that needed one. The feature sits in the wider family of nudging wilds; what makes xNudge different is the growing multiplier.

xNudge is a Nolimit City name. Other studios build similar nudging wilds under different labels, and the multiplier rules vary. Always read the game’s help screen for the exact version.

How the xNudge wild works, step by step

The sequence on screen looks like a chain of events, but the random number generator has already chosen the full result, including how far the wild moves, before the reels stop. The animation is a way of showing that result. In order, this is what happens:

1. You set a stake and press spin. The RNG picks the stop position for every reel, which fixes where the tall wild stack sits.
2. The reels stop. Part of the xNudge wild stack shows at the top or bottom of a reel, with the rest above or below the window.
3. The wild nudges one position at a time towards the centre until every row of that reel shows wild.
4. With each nudge step, the multiplier attached to that wild goes up by one.
5. Wins are counted. Any winning combination that runs through the wild reel is multiplied by that reel’s final multiplier.
6. In free spins on some games, the wild stays in place (sticky), keeping its multiplier for later spins.

A press report on the launch of El Paso Gunfight described it in one line: every time the special wild nudges, the win multiplier increases by one. The starting value, and what happens when two xNudge reels share a win, is set out in each game’s rules, so check the help screen rather than assuming.

A worked xNudge example on a four-row reel

Take an illustrative reel four rows high, holding a wild stack four symbols tall. The figures below show how the number of nudges, and so the multiplier, depends on how much of the stack was visible when the reel stopped. The starting value of x1 is an assumption for the example.

The counter-intuitive point is in the last row. A wild that barely scrapes onto the reel is worth more than one that lands neatly, because it has further to travel. That is the opposite of how a normal stacked wild behaves, where a full stack in view is the best result.

The multiplier only matters if the wild reel forms part of a win. A x4 wild on a spin where nothing else lines up pays nothing. On a ways to win layout, where wins only need matching symbols on adjacent reels, a whole wild reel takes part in a lot of combinations, which is why the studio pairs xNudge with ways and xWays grids.

Which xNudge slots can you play in the UK?

The xNudge slot in our verified data is El Paso Gunfight, released by Nolimit City in 2021. Its free spins round comes with jumping wilds and sticky xNudge wilds, and the base game lets you choose a High or Extreme reel set before you play. Other Nolimit City titles also use the mechanic; the safest way to confirm is the paytable or help screen of the game in front of you.

You can see the developer’s listing details mirrored on slotcatalog’s El Paso Gunfight page (opens in a new tab) and gambling.com’s UK El Paso Gunfight review (opens in a new tab). Read our full El Paso Gunfight slot guide for the paytable and free spins in more depth.

How xNudge changes the maths: RTP, volatility and max win

A feature never adds return on its own. The RTP of an xNudge slot is set for the whole game, and the multipliers are paid for by the rest of the maths: more blank spins, smaller base wins or a rarer bonus. What xNudge does is push value into fewer, larger results, which raises volatility. Nolimit City labels many of its games High, Extreme or Insane for that reason.

At 96.06%, the long-run average cost of El Paso Gunfight is about 3.94p for every £1 staked. That average only shows up over a very large number of spins; a single session can end far above or far below it. The table puts the figures in pounds.

The max win is a ceiling, not a target. The guide to max win caps explains how studios stop a game when it reaches its cap, and why the chance of getting there is tiny.

xNudge compared with other wild features

Several wild mechanics look alike in a short clip. The differences are in what moves and what grows.

• Standard nudging wild: slides to fill its reel but carries no multiplier, so the gain is the extra wild positions.
• Expanding wild: a single wild grows to fill its reel instantly, with no step count.
• Wild multiplier: a wild carries a set or random multiplier that doesn’t depend on movement.
• Sticky wild: a wild that stays put for later spins; El Paso Gunfight combines this with xNudge in free spins.
• xNudge: a nudging wild whose multiplier is tied to the number of steps it takes.

xNudge and the fruit machine nudge

The word nudge comes from British pub and arcade machines. On a Category C fruit machine, the game may offer a set number of nudges after a spin, and you press a button to move a reel down one position at a time. Dransfield Novelty of Leeds has claimed to have originated the nudge feature, a claim reported in 2019; our history of nudges and holds covers the background.

The difference is who does the nudging. On a fruit machine you choose where to spend offered nudges, and choosing well can avoid missing a win the machine has offered, although no technique beats the machine’s built-in payout percentage. On an online xNudge slot you choose nothing: the wild moves automatically to a result already decided. Our page on fruit machine nudges explains the pub version in detail.

xNudge myths and what is actually true

Every spin is independent. A part-visible wild that fails to join a win is a near miss, not a sign that the next spin will pay.

UK rules that shape xNudge slots

Nolimit City games supplied to Great Britain follow the Gambling Commission’s online slot design rules, in force since 31 October 2021. The Commission’s responsible product design standard (RTS 14) (opens in a new tab) is where those rules sit. In practice:

• No autoplay: each spin must be started by hand.
• Each spin takes at least 2.5 seconds, nudge animation included, and there is no turbo or slam-stop.
• A return equal to or smaller than the stake must not be celebrated as a win.
• Your balance and net position must be shown throughout the session.
• Bonus buy is not offered in UK versions, even where versions supplied elsewhere have it.

Stake limits also apply: £5 per spin for players aged 25 and over since 9 April 2025, and £2 for those aged 18 to 24 since 21 May 2025, as set out in the Commission’s online slots stake limit guidance (opens in a new tab). See our UK slot game design rules page for the full list.

How to check an xNudge slot’s rules and RTP

Before playing any xNudge game, open the game help screen, usually behind an i or menu icon. Look for the wild’s starting multiplier, whether multipliers on different reels add or multiply, whether the wild is sticky in free spins, the RTP figure and the max win. If you are unsure which RTP version a casino runs, our guide to finding a slot’s RTP explains where to look.
