The Tombstone No Mercy slot game has a 5 reel and 2-3-3-3-2 rows setup with 108 paylines to play with. A winning combination takes place when 3 or more matching symbols land left to right on adjacent reels.

Stakes start at 10p and go up to £20 per spin. You can use the coin icon on both desktop and mobile versions to see all available bet options. 

The RTP rate is 96.05%, which is slightly above the online slot average of 96% but is below its predecessor, Tombstone, which was 96.19%. Nolimit City also offers other RTP rates of 94.03% and 92.01%, depending on where you play.

You'll discover a hit frequency of 20.44% and an extreme volatility rating when playing. The original game was 20.32%, with a high volatility rating. 

Good news on the max win front: It has increased to 16,480 x the bet for this game, whereas it was 11,456 x the bet for the first game. This means the probability of landing the max win is 1 in 9 million.

Nolimit City has kept the same recognisable characters from the other Tombstone games. On the reels, you'll observe horse thief Skinny Joe, bank robber Edda Star and notorious bandit El Gordo. They make an appearance on the stacked Wild symbols in a Wanted poster format. We're told that this gang of outlaws are the quickest gunslingers in the entire Wild West.

The game is set in front of a wooden shack somewhere in the Frontier area of the US. A sepia colour scheme has been used with lots of cool touches, such as a gecko scrambling around the walls of the shack. The designer has added a refresh with a bit of red sewn in throughout the game, complete with an almost comic-book-strip touch to give a sleek finish. You can see a sun setting in the background to give it a warmer feel than the original game. The music has stayed the same and is the typical kind of theme music you'd hear in a classic Western film.

Character symbols on the reels in order of highest value first are sticks of dynamite, gold bullion, a sack filled with dollars, horseshoes, and a gun with bullets. These are then followed by the standard symbols of A, K, Q, and J.

Here are the values of the symbols:

• Sticks of dynamite: 5 =  4.80, 4 =  0.80 and 3 = 0.40 x the bet
• Gold bullion/sack of dollars: 5 = 3.20, 4 = 0.64 and 3 = 0.32 x bet
• Horseshoes/gun & bullets: 5 = 2.40, 4 = 0.56 and 3 =0.24 x the bet
• A, K, Q & J: 5 = 1.60, 4 =0.40 and 3= 0.16 x the bet
• Wild symbol substitutes for any other symbol except the Scatter and Badge symbols.
• Sheriff Badge symbol, when triggered along with other symbols, gets you entry into the Gunslinger Spins and Bounty Spins.  
• Marshall Badge symbol when triggered alongside other symbols get you entry into the Gunslinger Spins and Bounty Spins.

When playing the game on an iOS or Android device, it looks superb. The slot will adapt to whatever device you're using, which means you can be assured of a top experience whether you're using a smartphone, tablet, or desktop. 

The Tombstone No Mercy slot game is packed with top features, so read on to learn more about the all-guns-blazing details.

Outlaw Wilds

This feature utilises NLC's famed Xnudge functionality; it's a stacked 3-row high Wild which appears on reels 2, 3, and 4. The Wilds always nudge to be fully visible. For every step the Outlaw Wild nudges, the win multiplier increases by 1 each time.

Free Spins

There are 3 Free Spins bonus rounds up for grabs for the Tombstone No Mercy game:

• Justice Spins - Landing a Sheriff and Marshall Badge on reel 1 and reel 5 triggers this bonus round and gives you 3 Justice Spins. Outlaw Wilds stay throughout the Justice Spins round.
• Gunslinger Spins - Landing 3 Scatters awards you 10  Gunslinger Spins. The Outlaw Wilds will award an unlimited win multiplier that sticks for the entire bonus feature. For every step the Outlaw Wild nudges, the win multiplier increases by 1. Landing Scatters awards extra spins: 1 Scatter awards 1 extra spin, and 2 Scatters awards 3 extra spins.
• Bounty Spins - Triggered by landing Sheriff Badge, 3 Scatters and a Marshall Badge. Awards 12 Bounty Spins, with a combination of the features from Gunslinger Spins and Justice Spins. Outlaw Wilds will stick to the reels once landed and award a win multiplier for each nudge. For every step the Outlaw Wild nudges, the win multiplier increases by 1. Scatters awards additional spins. 1 Scatter awards 1 extra spin, 2 Scatters awards 3 extra spins.

Bonus Buy

Many newer slot games, have a Bonus Buy functionality however, this is not available in the United Kingdom. Use the yellow lightning button to access purchase options from the Bonus Buy section where there are the following options:

Tombstone No Mercy is an upgrade from the first game, and it's as enjoyable as the original with a few added extras. The Bonus Buys are a big addition if this functionality is allowed where you play. The game does feel more polished, and with 5,000 added to the max win amount, taking it up to 16,480 x the bet, this is something to shout about.

Tombstone RIP is another game in this popular series, released back in 2022 albeit with a slightly different style. It was much darker and gruesome, much more in line with NLC's sometimes macabre style. It offers 300,000 times bet max wins. NLC went one step further in January 2025 with the release of Tombstone Slaughter: El Gordo's Revenge. Similar to Tombstone RIP in many ways, it comes with even bigger win potential: a whopping 500,000 times your total bet!

Speaking of style, NLC games always stand out from the crowd for their high-quality creatives and headline-grabbing storylines. It's definitely the most original and quirky studio out there, and Tombstone No Mercy lives up to its reputation. A big plus point for me is that it's straightforward, as one negative of NLC can be its sometimes over complicated game rules. But this one focuses on xNudge Wilds and a decent Free Spins bonus rounds, which is a huge thumbs up from me. These features work fantastically together for an immersive gaming experience.
