Tombstone is a wild west themed slot game from NoLimit City featuring a 2-3-3-3-2 reel setup that can be played across all platforms and devices. The game is highly volatile and offers players a chance to win up to 11,456x their stake. The game features three outlaws as fully stacked wild symbols that can nudge into place via the xNudge feature. There is also a progressive multiplier in play that can increase to unlimited during one of the three different free spin features. Here are the game mechanics outlined in a bullet point list:

- Wilds: 3 Outlaw Wilds (fully stacked wilds) that land only on reels 2, 3, and 4.
- xNudge Feature: If the Outlaw Wilds don't land fully visible on the reels, they will be nudged in place to fill the entire reel every time. Every nudge that is needed to fill the reel, a progressive multiplier will increase from 1x to 3x for the given symbol.
- Free Spin Feature: There are 3 different types of free spin features.
- Justice Spins - Triggered by landing the sheriff and the marshall badge on reels 1 and 5. Players receive 3 free spins where all wilds that land on the reels become sticky wilds.
- Gunslinger Spins - Triggered by landing 3 scatters on the same spin. Players receive 10 free spins where the Outlaw xNudge wild multiplier has no upper limit, and every nudge increases the multiplier by 1x.
- Bounty Spins - Triggered by landing the sheriff and the marshall badge on reels 1 and 5, and 3 scatters. Players receive 12 free spins with all the benefits from both the Justice Spins and the Gunslinger Spins. Players receive 1 extra free spin for every new scatter they land.
- Symbols: The highest value symbol is the dynamite, and the low-value symbols are the royal card suit symbols. Players need to land 3 to 5 matching symbols on a payline to win.
- Bet Limits: Players can bet between 10p to £50 per spin.
- Jackpot: There is no jackpot, but players can win up to 11,456x their stake.
- Compatibility: The game can be played on mobile and tablet devices.
- Pros: Stacked wilds with xNudge progressive multiplier, 3 different free spins features, high volatility and 11,456x max win.
