Tombstone Slaughter Slot (Nolimit City)

The Tombstone Slaughter slot has 6 reels with 324 ways to win in a 2x3x3x3x3x2 formation. With more ways to win added via the various xMechanics (more details below), winning combinations are formed when 3 or more matching symbols appear across successive reels, in any position, and beginning from the leftmost reel. The highest payout is awarded per way to win.

Regarding bet options, you can play Tombstone Slaughter: El Gordo’s Revenge from as little as 20p a spin. With a maximum bet of £100 per spin, slot sites will surely limit the game’s bet limits due to the extremely high win potential of 500,000 times your total bet. To change your bet, press or click on the ‘Coins’ icon to see all options. Non-UK players can opt for Autoplay (up to 1,000 auto spins) and Turbo/Quick Mode.

The Tombstone Slaughter RTP rate is 96.01%, about the average of an online slot game. 63.49% is reserved for the base game with 32.52% for the bonus features. Nolimit City has also produced 94.08% and 92.05% RTP alternative versions which may be used at your chosen site. All free demo slots at OLBG use the highest RTP rate possible.

When it comes to volatility, this game is in the insane bracket and classed by Nolimit City themselves as 12/10! The hit frequency rate is 9.39% meaning a winning combination will form every 10.65 spins. Triggering any free spins feature will occur every 258 spins. It’s important to note these are average figures.

Finally, the Tombstone Slaughter slot comes with 500,000 times bet max wins. Yes, you read that right! This means this game has the highest payout slot of all time, surpassing the 300,000-times bet max win potential in Tombstone RIP. Known as El Gordo Revenged, the max win probability in the base game is 1 in 189 million spins. Winning 100 times your total bet or higher will occur every 805 spins (again, on average).

With a Wild West theme, the Tombstone Slaughter slot follows on from the Tombstone, Tombstone RIP and Tombstone No Mercy games. This time around, the story follows the aftermath of Gordo’s killing where he was publicly humiliated.

His daughter is on a mission for revenge by any means necessary even if that entails setting the town on fire and eliminating anyone in her path. The setting is a desolate Western town which has literally been burned to the ground (by El Gordo’s daughter). This is accompanied by a rather intense, stirring soundtrack which adds to the serious nature of what’s gone down.

On the reels, there are A, K, Q, J and 10 royals as the low-value symbols. The 5 higher-value symbols are all characters. Four of them appear to be dead as they have a sepia tone. Top of the bill is the El Gordo’s daughter symbol that pays 3 times your total bet for 6 in combination.

Tombstone Slaughter also comes with several special symbols including xNudge Wilds, Slaughter Scatters, Bonus and, importantly Revolvers. Details on these symbols can be found in the Bonus Features section below.

Tombstone Slaughter Mobile

As is the case with all Nolimit City slots, HTML5 technology is used to create the games. Tombstone Slaughter is compatible with desktop, mobile and tablet devices. If playing on a smartphone, Portrait Mode is available for iOS and Android devices making it perfect to play at mobile casino sites.

With lots to cover in the Tombstone Slaughter slot, I thought I would begin by explaining that the rightmost reel (i.e. reel 6) will only contain 2-high stacked Revolver or character symbols. The reel is inactive if half symbols land. Below, you’ll find details on the various bonus features including xRIP, xNudge, Quick Draw, Slaughter Spins, Massacre Spins and El Gordo's Revenge Meter. Remember, revenge is a dish best-served cold. 

xRIP

Are you ready? For starters, any spin in the base game or any bonus feature that awards a win that is less than your total bet will see the xRIP feature triggered. It means that no payout is awarded.

xNudge Wild

An xNudge Wild symbol always nudges to become fully visible and take over the reel. Appearing on the 4 middle reels, each nudge sees the wild multiplier increase by 1.

When a part of the xNudge Wild symbol appears on the reels, it nudges up or down until it’s fully visible on that reel. Multiple xNudge Wilds on the reels will see the multiplier values added to each other for a total wild multiplier value.

Slaughter Scatter

Look out for the Slaughter Scatter symbol as it only appears on the 4 central reels. Whilst landing 3 will trigger a free spins game (more information on those below), landing just 2 Slaughter Scatters will see them transform into Reel Split Wilds as well as splitting itself on other symbols on that reel in half. This doubles the number of symbols on that reel for more ways to win.

Quick Draw

Look out for the Revolver symbol which appears only on the last reel (i.e. reel 6) in the base game as well as the Slaughter Spins and Massacre Spins features. When you land a full Revolver symbol, you will activate 3 to 6 Cylinder features:

• Backstab Wild: transforms a random paying symbol on reels 2-5 wild.
• Shootout Wild: transforms all instances of a random paying symbol on reels 2-5 wild.
• xSplit: splits a randomly chosen symbol and doubles its size on reels 2-5. In the case of an xNudge, the multiplier is doubled.
• Infectious xSplit: splits all instances on reels 2-5 of a randomly chosen symbol and doubles its size.
• Justice Wild: places an x Wild at the position of a randomly chosen character symbol on reels 2-5, which then nudges up until the top of the reel. Each nudge increases the wild multiplier by 1.
• Boothill Multiplier: randomly selects a character symbol and gives a win multiplier ranging from 5x to 999x.

Slaughter Spins

Tombstone Slaughter comes with 2 free spins features. First up is the Slaughter Spins feature which is triggered by landing 3 Slaughter Scatter symbols during a base game spin (simultaneously). 5 free spins are awarded.

The last/rightmost reel always displays a full-character symbol containing a random wild multiplier between 5x and 99x or a Revolver symbol.

Under the reels, you’ll see El Gordo’s Revenge Meter which begins at level 1 and can go up to level 5 (more details on this further down).  As well as the Cylinder features from the base game, the Revolver can also trigger the following features:

• Killcount Multiplier: awards a multiplier between 1x and 89x to the future levels (or last level) on El Gordo’s Revenge Meter.
• Revenge Level Up: fills all the spots on El Gordo’s Revenge Meter which upgrades you to the next level.

If you trigger the feature with 4 Slaughter symbols in the base game, you’ll get 5 free spins as well as 2 spots on El Gordo’s Revenge Meter filled in. There is also an upgraded xNudge Multiplier for each revenge level as 1x, 4x, 5x, 6x and 7x respectively. Landing a full Revolver symbol upgrades the remaining free spins to the Massacre Spins feature with 2 additional free spins.

Massacre Spins

The Massacre Spins feature is triggered in the base game by landing 3 Slaughter Scatter symbols plus 1 Revolver symbol. 5 free spins are awarded. As well as the Slaughter Spins features, the Revolver symbol is sticky (remains fixed in position) on the last reel.

If you trigger the feature with 4 Slaughter Scatter symbols plus 1 Revolver symbol, you’ll get 5 free spins as well as 2 spots on El Gordo’s Revenge Meter filled in. There is also an upgraded xNudge multiplier for each revenge level as 1x, 4x, 5x, 6x and 7x respectively.

El Gordo’s Revenge Meter

As mentioned in the 2 free spins features, you’ll see El Gordo’s Revenge Meter under the reel area. Beginning at level 1 and going up to level 5, the starting multiplier for the xNudge wild is 1x, 2x, 3x, 4x and 5x respectively.

Look out for Bonus symbols landing during the free spins features on reels 2, 3, 4 and 5. Each Bonus symbol rewards you with 1 extra free spin on the current level and fills El Gordo’s Revenge Meter by 1 spot.

This also increases the multiplier for future levels by 1. When you collect 4 Bonus symbols, the revenge meter moves to the next level (once all the current free spins have played out).

Nolimit Booster

Tombstone Slaughter: El Gordo’s Revenge also benefits from the Nolimit Booster feature. Increasing your chances of landing Slaughter symbols, the RTP rate also increases (the rates shown are for the highest RTP setting).

• xBet: At a cost of 1.2 x your total bet, you are guaranteed a Slaughter Scatter symbol on reel 2. The RTP rises to 96.1%.
• Super xBet: At a cost of 15 x your total bet, you are guaranteed 2 Slaughter Scatter symbols. The RTP rate increases to 96.17%.
• xNudge Booster: At a cost of 35 x your total bet, you are guaranteed 2 xNudge Wilds. The RTP rate is 96.12%.
• xNudge & Revolver Booster: At a cost of 3,000 x your total bet, you are guaranteed 1 xNudge Wild plus 1 fully stacked Revolver symbol. The RTP rate is 96.13%.

The latter 2 options are not available to UK players. 

Nolimit Bonus

Players located outside the UK can make use of the customary Nolimit Bonus feature. With 3 options available, the table below contains all the details:

With the Lucky Draw option, there is a 90% chance of triggering the Slaughter Spins feature whilst its 10% for the Massacre Spins feature.

Following on from previous Tombstone games, the Tombstone Slaughter slot offers a more brutal environment in which El Gordo’s daughter avenges her father’s death and humiliation. Graphically, the Western town is in flames marking the no-nonsense approach from the bereaved daughter.

Nolimit City has kept the xRIP feature where a win under your total bet is discarded. With xNudge Wilds and increasing multipliers, 2 Slaughter Scatters transform into Reel Split Wilds as well as other symbols on the reel for more ways to win.

However, the most important symbol is the Revolver which (when landing fully) activates up to 6 Cylinder features including Backstab Wilds, Shootout Wilds, xSplits, Infectious xSplits, Justice Wilds and Boothill Multipliers (up to 999x). That said, I found the base game to dish out plenty of nothing spins with small wins the majority of the time.

Then you have 2 free spins features where a full-character symbol with a random wild multiplier up to 99x or a Revolver symbol appears on the last reel. With extra Cylinder features, the key is to collect Bonus symbols which fill El Gordo’s Revenge Meter. With extra free spins awarded, the xNudge Multiplier increases each time. In the Massacre Spins feature, the Revolver symbol always appears meaning more Cylinder features come into play.

Overall, Nolimit City has created another masterpiece. Offering 500,000 times bet max wins, the Tombstone Slaughter slot game is the highest-paying slot of all time. Will NLC go bigger in future, though? We all thought this when they released San Quentin in 2021 (150,000 x bet), Tombstone RIP in January 2022 (300,000 x bet) and San Quentin 2: Death Row in September 2024 (200,000 x bet).

With Wild West-themed slots so popular, it's safe to say that Tombstone Slaughter is the new sheriff in town. However, El Gordo’s daughter will more often than not burn down the entire town, with you in it.
