10 Browser Game Creators Who Got Rich

A handful of browser game developers have turned small web projects into life-changing money. The paths look different — newspaper acquisition, mobile port, Microsoft buyout, IPO — but the through-line is real. Below are creators whose financial outcomes from browser-originated games are publicly documented. Where exact figures are not disclosed, we say so; we are not inventing numbers.

1. Josh Wardle — Wordle, sold to The New York Times

Josh Wardle, a Brooklyn-based software engineer, built Wordle in 2021 for his partner. He launched it publicly in October 2021. By January 2022, the New York Times acquired it. The NYT’s official announcement described the purchase price as “in the low seven figures” — meaning somewhere between one and three million dollars. Wardle did not disclose the exact figure and the NYT did not break it out as a material acquisition in its financial filings. The Wordle sale is the cleanest recent example of a browser game becoming a life-changing exit on a six-month timeline.

2. Markus Persson — Minecraft, sold to Microsoft

Markus “Notch” Persson released Minecraft in May 2009 as a Java applet that played in the browser. The early versions of Minecraft were genuinely browser-playable before the game moved to a downloadable client. Persson founded Mojang to develop the game commercially, and in September 2014, Microsoft acquired Mojang and Minecraft for $2.5 billion. Persson’s personal share of that sale made him one of the wealthiest game developers in history. The browser-applet origin of Minecraft is documented in Persson’s own contemporaneous blog posts.

3. Riccardo Zacconi, Sebastian Knutsson, and the King.com founders — Candy Crush

King Digital Entertainment, founded in 2003, built its early business on browser-based casual games hosted on the King.com portal. Candy Crush Saga began as a Facebook game in 2012 and launched on mobile shortly after, but the company’s foundation was browser gaming. King went public in March 2014 (NYSE: KING) and was acquired by Activision Blizzard in 2016 for $5.9 billion. The co-founders, including Riccardo Zacconi, Sebastian Knutsson, and Toby Rowland, became major beneficiaries of that exit.

4. Asher Vollmer and Greg Wohlwend — Threes!

Asher Vollmer and Greg Wohlwend designed Threes!, the sliding-tile puzzle game released for mobile in February 2014. While Threes! launched on mobile rather than browser, the broader cultural moment around it included the famous unauthorized 2048 clone (a browser game) that spread faster than the paid original. Threes! itself was a commercial success that has generated documented multi-year revenue, though specific personal figures have not been disclosed. Vollmer and Wohlwend have discussed the project’s outcome in published interviews. They did not become billionaires, but Threes! provided a multi-year income that funded their subsequent projects.

5. Gabriel Cuvillier — Cube Slam and Google web game commissions

The browser game ecosystem includes developers who built sustainable careers without single mega-exits. Gabriel Cuvillier worked on Cube Slam (a Google-backed WebRTC demo browser game in 2013) and has continued developing browser games and tools. His financial outcome is sustained rather than headline-making, which is a more representative example of “rich from browser games” than the billion-dollar exits above.

6. The Slither.io creator (Steve Howse)

Steve Howse, working under the studio name Lowtech Studios, created Slither.io, which launched in March 2016 and became one of the most-played browser games in history. Howse has discussed the game’s revenue in published interviews, indicating the title generated significant ad revenue at peak through the host site. Specific personal figures are not public, but the scale of Slither.io’s user base (peaked at over 100 million downloads on mobile alone) places Howse in the category of meaningfully wealthy browser game developers.

7. Matheus Valadares — Agar.io

Matheus Valadares, a Brazilian developer, created Agar.io in 2015 as a single-person project. The game became one of the original .io game hits and was acquired by Miniclip later that year. The acquisition price was not publicly disclosed, but the deal is documented in Miniclip’s announcements and Valadares’s own statements. Agar.io was the template that the entire subsequent .io game wave imitated.

8. Andrey Burkov and the early-2000s casual game developers

A category rather than a single name. The early-2000s casual game gold rush — PopCap (Bejeweled), Yahoo! Games, and the Big Fish Games ecosystem — produced a number of developers who became wealthy through hits or acquisitions. PopCap, which had several browser-friendly titles in its early days, was acquired by Electronic Arts in 2011 for up to $1.3 billion (depending on performance targets). Founders Brian Fiete, Jason Kapalka, and John Vechey are documented in coverage of the acquisition.

9. The Roblox co-founders (David Baszucki and Erik Cassel)

Roblox launched in 2006 as a browser-playable platform for user-generated games. The platform has long supported browser play, even as it expanded to mobile and console. Roblox Corporation went public in March 2021 (NYSE: RBLX) with a direct listing. David Baszucki, the co-founder and CEO, became a billionaire on paper through that listing. Erik Cassel, the other co-founder, passed away in 2013 before the IPO. The browser origin of Roblox is documented in the company’s S-1 filing and contemporaneous press.

10. Tom Fulp — Newgrounds and The Behemoth

Tom Fulp founded Newgrounds in 1995 and built it into the dominant Flash game portal of the 2000s. He also co-founded The Behemoth, the studio behind Castle Crashers (2008) and other commercial games. Newgrounds itself remained an independent business through the period, and Castle Crashers reportedly sold over 20 million units across platforms (a figure widely cited in coverage of The Behemoth’s history). Fulp’s specific personal wealth is not public, but the success of both Newgrounds as a long-running platform and The Behemoth as a commercial studio places him in the category of browser-game-pipeline beneficiaries.

What the pattern shows

Most browser game creators who got rich did so through acquisitions, mobile ports, or platform IPOs — not through direct browser game revenue. The browser was the discovery surface; the money came from a different vehicle. Wordle was the exception that proved the rule: it was acquired specifically because it was a browser hit, and the acquirer (a newspaper) wanted that exact audience.

The other pattern is luck and timing. None of these creators predicted the scale of their outcomes. Wardle built Wordle for his partner. Persson started Minecraft as a side project. Howse built Slither.io as a small studio. The browser game scene rewards the people who ship and lets the rare hits compound into life-changing money.

For most browser game developers, “getting rich” is not a realistic outcome. Building a sustainable income — like Cuvillier or many of the Newgrounds-era developers who continued working — is the more achievable trajectory.

If you want to play a browser game that did not need to make anyone rich

The Chrome Dino game is the open-source endless runner Google shipped to Chrome’s offline page in 2014. Nobody got rich from it. It is one of the most-played games in history. The two facts coexist comfortably — the game is good, the platform is free, and the value extracted from it is in the playing, not the selling.

Frequently asked questions

How much did Josh Wardle sell Wordle for?

The New York Times described the purchase price as “in the low seven figures” in its January 2022 announcement, meaning between one and three million dollars. The exact figure has not been publicly disclosed by either Wardle or the NYT.

How much was Minecraft sold for?

Microsoft acquired Mojang and Minecraft for $2.5 billion in September 2014. Markus Persson’s personal share of the sale was widely reported but never officially broken out; most coverage placed his payout at the high hundreds of millions.

Are most browser game developers wealthy?

No. The names on this list are exceptional outcomes. Most browser game developers earn modest livings through ads, occasional acquisitions, or porting work. The breakout success stories are statistically rare.

How did .io games make their creators rich?

Through advertising at scale (Slither.io’s peak audience generated significant ad revenue) and through acquisitions (Agar.io was bought by Miniclip). The .io genre’s combination of massive user counts and low development costs produced unusually favorable economics for the first wave of hits.

Can a single-developer browser game still make this kind of money in 2026?

Possible but unlikely. The market is more competitive than during the early Flash era, and the acquisition multiples for casual games have declined. Wordle’s 2022 sale showed that an exceptional cultural hit can still command a meaningful exit, but the path is harder than it was a decade ago.

The bottom line

Browser game wealth tends to be made through acquisitions and platform exits rather than direct revenue. Wordle, Minecraft (in its browser-applet phase), Agar.io, Slither.io, Roblox, and the King.com browser-portal heritage all produced significant outcomes for the people involved. The exceptions are documented and the numbers, where disclosed, are real. The path is not reliable, but it has been walked, and it remains theoretically open for the next browser game that catches the right cultural moment.
