The History of Voodoo Games (Hyper-Casual Empire)

Voodoo is the French studio and publisher that more or less defined hyper-casual mobile gaming. Founded in Paris in 2013, the company built a portfolio of simple-mechanic games that dominated mobile app store charts in the late 2010s and bled into the browser games market along the way. The history of Voodoo Games is the history of a publishing model that turned out to be extremely effective at scale — ship lots of small games fast, find what sticks, scale the winners.

The founding

Voodoo was founded in 2013 in Paris by Alexandre Yazdi and Laurent Ritter. Both founders came from the mobile gaming space — Yazdi had previously worked in mobile game development and analytics. The original Voodoo wasn’t yet the hyper-casual publisher it would become; the company spent several years experimenting with formats before landing on the model that defined it.

The early-to-mid 2010s mobile games market was crowded with mid-tier free-to-play games — match-three games, casino apps, base-builders. Voodoo’s eventual approach went the opposite direction. Instead of building deep monetized games, they bet on extreme simplicity: one-mechanic games that anyone could play for a minute or two, monetized entirely through ads.

The hyper-casual model

By 2017 Voodoo had codified what came to be called hyper-casual gaming. The model has a few defining traits:

• Single mechanic. The whole game is one action — tap, swipe, balance, stack. You learn it in three seconds.
• Short session length. Sessions are typically under five minutes. Players come back many times per day.
• Ad-only monetization. No in-app purchases as the main revenue. Interstitial ads between runs and rewarded video for bonuses.
• Rapid prototype testing. The studio prototypes dozens of game concepts, A/B tests them in low-cost ad campaigns, and only scales the ones with proven CPI (cost per install) economics.
• Network as platform. Each game cross-promotes the others through internal ad placements. The portfolio compounds.

This model wasn’t unique to Voodoo — Ketchapp had pioneered something similar earlier — but Voodoo industrialized it. The company built internal tools, partnerships with external developers, and a publishing pipeline that could test and ship games in weeks rather than months.

The breakout hits

Stack (2016)

Stack was an early Voodoo-distributed hit. The premise was minimal: blocks slide back and forth, and you tap to drop them onto a tower. Misalign and the overhang gets cut off. The challenge grew naturally as the tower got narrower. Stack hit top-charts positions in many countries and became a template for the hyper-casual format that followed.

Helix Jump (2018)

Helix Jump was a vertical-descent puzzle where a ball bounces down a spiral tower of platforms. Tap to rotate the tower, dodge the colored platforms, fall through the gaps. Massively addictive in 60-second bursts. Helix Jump was downloaded hundreds of millions of times.

Hole.io (2018)

Hole.io took the .io multiplayer concept (a la Agar.io, Slither.io) and applied it to a different mechanic — you control a black hole that swallows objects to grow larger, competing with other holes to eat the most of a city map. The game went viral in 2018 and remains one of Voodoo’s most recognized titles. The browser version helped extend Voodoo’s reach beyond mobile-only.

Aquapark.io (2019)

Aquapark.io was a slide-racing game — players slide down water slides, jump between tracks, and try to reach the finish first. Another massive download success that demonstrated Voodoo’s ability to consistently produce hits rather than getting lucky once.

The Tencent investment

In August 2018, Tencent invested in Voodoo in a deal that reportedly valued the company at over $1.4 billion. The investment was framed as a strategic partnership giving Tencent exposure to hyper-casual gaming and Voodoo access to Tencent’s distribution in China and other Asian markets.

The deal validated the hyper-casual model at a moment when hyper-casual was at peak attention from the broader mobile games industry. It also gave Voodoo capital to expand beyond pure hyper-casual into adjacent genres.

The browser games angle

Voodoo is mobile-first, but several of its biggest titles have notable browser presences. Hole.io has a popular browser version played on multiple HTML5 portals. Stack and Helix Jump have browser ports. The studio’s mechanics travel well to web because they’re built around minimal input and short sessions — exactly the constraints that work in a browser tab.

For browser game discovery sites, Voodoo’s titles are reliable inclusions in “best .io games” and “best casual browser games” lists. The hyper-casual aesthetic and short-session design fit the browser context naturally.

The post-peak diversification

The hyper-casual boom peaked around 2018-2020. By the early 2020s, the ads-only economics had tightened — rising CPI costs and platform changes (Apple’s IDFA changes in 2021 especially) compressed margins. The biggest publishers, including Voodoo, started looking beyond pure hyper-casual.

Voodoo’s diversification has included casual games with deeper progression (still ad-supported but with longer player retention), mid-core experiments, and acquisitions of other studios. The company has acquired several mobile and PC games studios to expand its portfolio beyond hyper-casual mechanics.

Notably, Voodoo acquired the casual mobile publisher BeReal (the photo-sharing app, not a game) in 2024, signaling expansion well beyond games. The strategy reflects an evolving business model less dependent on the hyper-casual format that originally defined the company.

The publishing model’s lasting impact

Voodoo’s approach influenced mobile games publishing broadly. The “test many prototypes, scale the winners” model is now standard at hyper-casual and casual publishers. Tools and methodologies pioneered by Voodoo and Ketchapp became industry conventions.

On the developer side, the hyper-casual publishing deal — usually a revenue share with the publisher handling user acquisition — let solo developers and small studios reach audiences they couldn’t have reached independently. Many breakout developers have signed deals with Voodoo specifically.

The Voodoo aesthetic

Voodoo games share an unusual visual coherence. The art style across their catalog tends toward bright pastel colors, smooth low-poly geometry, simple cartoon characters, and clean UI. This wasn’t accidental — the studio standardized art direction across titles to make their games immediately recognizable.

The look has been imitated widely enough that “Voodoo-style hyper-casual” is now a recognizable aesthetic category. The visual coherence helps with cross-promotion between titles in the portfolio — a player who likes one Voodoo game finds others visually familiar.

Voodoo in 2026

In 2026, Voodoo remains one of the largest mobile game publishers globally and has expanded into casual and mid-core titles alongside its hyper-casual catalog. The company employs over 700 people across offices in Paris and elsewhere. The hyper-casual market has matured into a smaller but still meaningful segment, and Voodoo continues to ship in it while pushing into adjacent categories.

The browser games audience knows Voodoo primarily through Hole.io and a handful of other ports. Mobile is still the company’s center, but the browser footprint is real.

For a one-mechanic, no-download browser experience that predates the hyper-casual boom, the T-Rex Runner is still here — older than Hole.io, smaller in scope, but in the same minimalist lineage.

Frequently asked questions

Voodoo was founded in 2013 in Paris by Alexandre Yazdi and Laurent Ritter. Both remain associated with the company; Yazdi has been the public face for much of Voodoo’s media coverage.

What is Voodoo’s most famous game?

Hole.io (2018), Helix Jump (2018), and Stack are the most recognized titles. Hole.io has the strongest browser presence; the others are primarily mobile but have been ported to web.

When did Tencent invest in Voodoo?

August 2018. The investment reportedly valued Voodoo at over $1.4 billion and gave Tencent strategic access to hyper-casual gaming while Voodoo gained capital and Asian market access.

What is hyper-casual gaming?

Hyper-casual games are mobile games with single-mechanic gameplay, short session lengths, and ad-only monetization. Voodoo and Ketchapp defined the format. Examples include Stack, Helix Jump, and Hole.io.

Is Voodoo still making hyper-casual games?

Yes, but the company has diversified well beyond pure hyper-casual into casual, mid-core, and even non-game products. The hyper-casual market matured and tightened economically through the early 2020s, prompting the strategic broadening.

The bottom line

Voodoo turned a publishing methodology — test many small games, scale the proven winners, monetize through ads — into a billion-dollar business. The company’s catalog reshaped the mobile games charts for several years and produced a handful of browser games (Hole.io most notably) that remain in regular rotation today. The hyper-casual era it defined has cooled, but Voodoo’s influence on how casual mobile games are built and published is durable.
