Buckshot Roulette: a $1 side project becomes a 4-million-copy horror hit

Mike Klubnika, an Estonian solo developer and musician known for experimental horror titles, started learning 3D art around 2018 and eventually challenged himself to finish a small game in two months. By the end of 2023 he had released 16 small games between studying and full-time jobs, supported by a modest community rather than relying on any of them for income.

Build a $1 shotgun-roulette horror game with 15-minute rounds, release it quietly on itch.io, and let streamers turn it into a viral hit.

Klubnika released Buckshot Roulette on itch.io in December 2023, selling it for about a dollar. The game is a tense tabletop take on Russian roulette: players face an AI dealer with a 12-gauge shotgun and use items to tilt the odds, in sessions designed to be short and highly replayable. A version 1.2 with new features launched on Steam on April 4, 2024, published by Critical Reflex and priced at $2.99, where it collected an overwhelmingly positive rating.

Buckshot Roulette became one of 2024's breakout indie hits. Within days of its Steam launch it peaked at 6,321 concurrent players with over 75,000 live Twitch viewers, then hit 500,000 copies by April 9, one million on Steam alone by April 17, two million by July 5 and four million by December 10, 2024. A free multiplayer update on October 31 pushed its concurrent peak past 20,000.

Mike Klubnika is an Estonian solo developer and musician who had been making experimental games for years before any of them broke out. He told the Godot Engine team that he began learning 3D art around 2018, then decided to build a small game in two months; by the end of 2023 he had released 16 small games between studying and full-time jobs, feeling free precisely because he never needed any of them to turn a profit.

Buckshot Roulette, released on itch.io in December 2023 for about a dollar, is a macabre tabletop game of chance: the player faces a shotgun-wielding AI dealer in Russian roulette and uses items like cigarettes and handcuffs to bend the odds. Game World Observer described it as built around short sessions with high replayability, which made it a natural fit for streaming.

A version 1.2 with an online leaderboard and gamepad support reached Steam on April 4, 2024 through publisher Critical Reflex at $2.99. It peaked at 6,321 concurrent players within days and drew more than 75,000 simultaneous Twitch viewers at launch, then raced through sales milestones: 500,000 copies by April 9, one million on Steam alone by April 17, two million by July 5 and four million by December 10, 2024.

Klubnika kept the momentum with free updates, and the multiplayer mode released on October 31 pushed the game's peak concurrent count past 20,000 in early November. The mainstream success let him make games full time for the first time, and by 2026 he was sponsoring the Godot engine as a Corporate Platinum donor while working on his next title, s.p.l.i.t.

Short, replayable rounds were made for clips: the Steam launch alone drew over 75,000 live Twitch viewers.

A dollar on itch.io and a $2.99 Steam price turned viral attention into near-frictionless impulse purchases.

Sixteen small games over several years built the craft, the style and the audience that the hit could finally convert.

Free updates and a multiplayer mode repeatedly re-spiked interest instead of letting the game fade after launch week.

A tiny game can carry itself when the price is an impulse buy and rounds are short enough to stream: years of small experiments built the craft, then audiences did the marketing.

Buckshot Roulette kept selling after its December 2024 milestone and Klubnika continued shipping free content for it, including the multiplayer mode that reignited player counts. In a February 2026 Godot Engine showcase interview he described being able to develop games full time for the first time and announced that his more narrative-heavy hacking horror s.p.l.i.t was in the works, alongside his role as a Corporate Platinum sponsor of the Godot Development Fund — a small game priced at a dollar having funded a solo career.
