Tombstone Slaughter: El Gordo’s Revenge slot

Tombstone Slaughter: El Gordo’s Revenge slot overview

This is the latest entry in Nolimit City’s Tombstone series, a set of dark Wild West games that sits within our Tombstone slots series. Nolimit City, part of Evolution since a deal announced in June 2022, has built a reputation for games with enormous ceilings, and El Gordo’s Revenge pushes that further than anything else in our database.

The figures are the published specification as listed on the OLBG Tombstone Slaughter page (opens in a new tab). Your casino’s game rules show the RTP version actually in play.

How the features work in Tombstone Slaughter

Tombstone Slaughter: El Gordo’s Revenge centres its bonus on one round, Slaughter Spins, and one special symbol, the Quickdraw Revolver Wild. The free spins arrive through ordinary paid spins on the six-reel, 324-ways layout, and the wilds are what give the round its character.

Slaughter Spins

Slaughter Spins is the game’s free spins round. Once it’s triggered, spins no longer come out of your balance, and the wins they produce are counted up and paid when the round finishes. Since feature buys aren’t offered to British players, the round can only be reached by playing; there’s no menu option to jump straight in.

Quickdraw Revolver Wilds

A wild stands in for the regular paying symbols, helping to finish combinations that would otherwise fall one symbol short. The Quickdraw Revolver Wild is this game’s special version of it. It sits at the heart of Slaughter Spins, so how the round goes depends heavily on how these wilds land.

On an insane-volatility game, that dependence matters. Most of a session is base spins, many bonus rounds return modest amounts, and the 500,000x ceiling sits at the far end of a very long tail. The wilds and the round together are where that tail comes from.

Our checked data doesn’t cover the trigger for Slaughter Spins, the number of spins or exactly what a Quickdraw Revolver Wild does beyond substituting. The help screen sets those out, together with the RTP version your casino runs.

Why a 2-3-3-3-3-2 layout gives 324 ways

The reels are shaped like a diamond on its side: two symbols on the outer reels and three on each of the four middle reels. Wins pay for matching symbols on adjacent reels from the left, so the number of ways to win is the reel heights multiplied together.

The short outer reels keep the base ways count modest. As always, the ways count shapes how wins look, not the long-run return, which is fixed by the paytable at the published RTP.

Slaughter Spins and Quickdraw Revolver Wilds

The main feature is Slaughter Spins, a free spins round triggered in play, built around Quickdraw Revolver Wilds. Wild symbols substitute for paying symbols to complete wins, and in Nolimit games they often carry extra behaviours such as multipliers or movement.

How Slaughter Spins is triggered, how many spins it gives and exactly what a Quickdraw Revolver Wild does are details we have not been able to verify from Nolimit City, so we do not describe them. Read the help screen before playing: on a game this volatile, knowing where the value sits is the best protection against unrealistic expectations.

Nolimit City supplies many markets and some videos show bonus-buy menus. Since a Gambling Commission warning in January 2020, feature buy-ins are not offered to British players, so in the UK Slaughter Spins can only be reached through normal play.

What an insane volatility rating means for your money

Insane is the label Nolimit City gives this game, and it sits above high on any ordinary scale. It means the 96.01% return is spread extremely unevenly: a great many spins return nothing or a fraction of the stake, and a large part of the return is packed into rare, very large outcomes. Our slot volatility guide covers the general idea.

Here is what that does to a session. The average cost per £100 staked at the 96.01% version is £3.99, but most real sessions will finish below that average, because the few sessions that hit huge results pull the average up. Budget on the basis that a session can lose its whole stake without seeing the bonus.

The average column is useful for planning over many sessions; the right-hand column is the honest description of any single one.

The 500,000x max win: the maths of a giant ceiling

The top prize is 500,000 times your stake, the highest of any slot we list. Before it, the series high was 300,000x on Tombstone RIP. What the cap means in pounds:

Neither Nolimit City nor reference listings publish how often the cap is reached, and we do not quote third-party estimates. But simple expected value arithmetic shows why it must be extraordinarily rare. Suppose, purely as an illustration, that the 500,000x result accounted for one percentage point of the 96.01% RTP. Then its chance per spin would be 0.01 ÷ 500,000, or 1 in 50 million. Even at the 2.5-second legal minimum, 50 million spins would take nearly four years of non-stop play. The real figure is not published and could be rarer or less rare, but the order of magnitude makes the point.

Casinos can also set their own maximum payout per game or per day in their terms, which may sit below the game’s cap at higher stakes. Check those before assuming the full ceiling applies.

Tombstone Slaughter RTP and lower versions

The top published RTP is 96.01%. Lower versions exist, but we have not confirmed their figures. Nolimit City’s San Quentin 2: Death Row gives a sense of the range the studio uses, with versions at 96.13%, 94.03% and 92.11%. On that pattern, moving from the top version to the lowest would cost about £4 more per £100 staked. Check the line in the game rules before you play.

Tombstone Slaughter against Tombstone RIP and other insane slots

The RTPs are almost identical across the group, so the cost per £1 staked is nearly the same. What differs is how far the tail stretches. El Paso Gunfight is a calmer western from the same studio, with the option of a high reel set. More cowboy-themed games are in our Wild West slots collection.
