The latest unexpected Steam hit is a $3 must-play and it may still hit greater heights after nearly 7,000 glowing reviews as the dev looks to add multiplayer

After quietly roiling away on Itch.io for a few months, bite-sized strategy gambling game Buckshot Roulette has come to Steam and instantly become one of the most popular and highest-rated PC games of the year. It only costs $3 ($2.69 thanks to an ongoing sale), you can finish it in well under an hour, and there's a very good reason that it's gotten over 6,600 user reviews with a 96% positive score since its April 4 Steam launch. 

Created by Mike Klubnika and based on Russian Roulette, Buckshot Roulette is quite literally a game about shooting yourself in the face with a shotgun – or rather, trying not to do that, and instead having your opponent swallow the live shells while you skirt death with harmless blank shells. 

In a seedy underground club, you sit down at a table – after signing a waiver, obviously – with a monstrous dealer, a shotgun, and a random assortment of tools that manipulate the shotgun. You and the dealer take turns staring down the barrel and pulling the trigger, betting on careful item usage and some help from Lady Luck to help you dodge the titular buckshot. 

See, you and the dealer each have a set health pool, and each live round of buckshot you take understandably knocks off one point. The first to hit zero health loses. It's the items that make this more than a game of pure chance. You can burn a magnifying glass to sneak a peek at the next shell in the chamber, saw off the barrel for double damage on the next shot, inhale a cigarette to inexplicably regain a point of health, straight-up remove a shell from the chamber, and more. Small interactions in a simple game loop quickly pile up to become an engrossing, atmospheric, almost tabletop experience that never fails to quicken my pulse. 

Buckshot Roulette is a certified viral hit, and many fans are saying the same thing: this is crying out for PvP. For once, I actually agree with the "add PvP" crowd, and Klubnika has clearly heard this feedback. In a Steam post outlining the added features
