Wild symbols in slots

What wild symbols do in slots

A standard wild replaces all symbols except scatters to help form a winning combination, as this guide to slot features (opens in a new tab) explains. If you have two cherries on a line and a wild in the third position, the game treats the wild as a third cherry and pays the three-cherry prize.

The exceptions are where games differ. Wilds almost never stand in for scatter symbols, and whether they can replace a bonus or feature symbol depends entirely on the game's rules. Some wilds also pay as a symbol in their own right when several land together. The help screen is the only reliable guide.

Wilds work with every win system. On a payline slot a wild fills a gap in a line; in a ways to win game it counts as an extra copy on its reel, multiplying the number of winning ways; in a cluster pays game it can join two groups into one. Our slot features hub covers the other mechanics.

How a wild completes a win: step by step

1. The reels stop and the game finds every wild on the grid.
2. For each line, way or cluster, it tests whether a wild can stand in for a symbol to complete a win.
3. Where a wild could complete more than one combination, games normally pay the highest available win on that line; check the help screen to confirm.
4. Any multiplier on the wild is applied to the win it helped create.
5. All wins from the spin are added together and paid.

Wild symbols maths: how much a wild helps

A short calculation shows the effect. Take a made-up game where a given symbol fills any reel position with a chance of 1 in 10, and add a wild with a chance of 1 in 20. A position now counts as that symbol with a chance of 1/10 + 1/20 = 3/20. The odds of a run starting from reel 1 on one line change like this:

The longer the run, the bigger the boost, because the wild's help compounds across every reel. But nothing here makes the game cheaper. The developer knows exactly how often wilds land and sets the paytable so the game returns its published RTP. Without wilds, the same game would simply pay more per combination.

Types of wild symbols in slots

Most games build on the basic wild with a behaviour of their own. The descriptions below are general; each game's rules decide exactly how its wild works.

Our separate guides to expanding wilds and sticky wilds go into those two types in more detail.

Nudging wilds and whole-reel wilds

Nolimit City's xNudge wild nudges to fill the whole reel when it lands partly visible, and each cell it moves adds one to its multiplier, according to this summary of Nolimit City's x-mechanics (opens in a new tab). In Mental II, xNudge wild multipliers combine into a total, and an xSplit symbol striking an xNudge wild raises its multiplier by one, as this studio showcase of Mental II (opens in a new tab) describes. See our Mental 2 review and our page on xWays and xNudge.

Hacksaw Gaming takes another route. In Bullets and Bounty, reels expanded by DuelReels act as wilds, according to this Bullets and Bounty launch report (opens in a new tab). Our DuelReels guide explains how the duel multipliers are set.

Multiplier wilds: adding or multiplying?

When two multiplier wilds help the same win, games combine them in one of two ways, and the help screen will say which. The gap grows quickly as multipliers rise.

Games that multiply wild multipliers together tend to be more volatile, because more of their return comes from rare stacks of high multipliers. Our guide to slot multipliers has more examples, and our multiplier glossary entry gives the short definition.

Slots with notable wild symbols

Published specifications for games in our reviews whose main feature centres on wilds. RTPs are default or top versions; check the help screen for the version your casino runs.

What wild symbol slots cost: RTP versions matter more

A clever wild doesn't change the price of play; the RTP does. The average cost is the total staked multiplied by the house edge, 100% minus the RTP. 2 Wild 2 Die is published in four versions, which makes the point clearly.

The same game, with identical wilds, can cost more than three times as much per pound depending on the version. Our explainer on why slots have different RTPs at different casinos covers how to check.

Wild symbol myths

• Myth: a wild landing just off a line means one is coming. Each spin is independent; a near-miss changes nothing about the next result.
• Myth: sticky wilds mean you should keep spinning. Sticky wilds work within a feature's own rules; they aren't a reason to stake more or play longer.
• Myth: wilds always replace bonus symbols. Many games exclude scatters and some bonus symbols; check the help screen.

More of these beliefs are covered in our guide to slot machine myths.

UK rules for slots with wild features

Wild features don't change the UK rules that apply to every online slot. The stake limit is £5 per game cycle for players aged 25 and over and £2 for those aged 18 to 24, and features within the spin don't add to it; see our slot stake limits page. Spins must take at least 2.5 seconds, and autoplay, turbo and slam-stop are banned.

Games also can't celebrate a return less than or equal to the stake, so a wild that completes a 5p win on a 20p spin shouldn't trigger a fanfare. And since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so wild-packed bonus rounds have to be reached through normal play. Our pages on UK game design rules and feature buy rules have more.
