How Browser Gaming Went From Flash Player's Death to 100 Million Monthly Players

When Adobe pulled the plug on Flash Player at the end of 2020, millions of browser games went dark overnight. For years, Flash had been the backbone of browser gaming. Its shutdown felt like an extinction event.

But something unexpected happened. Browser gaming didn’t collapse. It evolved.

Today, platforms like Poki serve over 100 million monthly players, with 625 million total players recorded in 2025. The technology that was supposed to kill browser gaming actually made it stronger.

In a recent interview with Mobidictum, Poki co-founder Michiel van Amerongen shared insights into how the platform navigated Flash’s collapse and grew into one of the world’s largest web gaming platforms. The company’s journey offers a window into how browser gaming survived and thrived.

The flash player collapse

Flash Player officially ended support on December 31, 2020. Chrome, Firefox, Edge, and all major browsers stopped supporting the technology immediately.

Adobe cited security vulnerabilities as the primary reason for the shutdown. Flash had become a favorite target for cyberattacks, with frequent exploits appearing faster than Adobe could patch them. Microsoft announced it would remove Flash support from Edge and Internet Explorer by the end of 2020, giving developers time to transition.

For players accustomed to quick browser games during lunch breaks, the loss was immediate. Popular titles vanished. Entire gaming sites went offline. But developers had been preparing for this moment longer than most players realized.

HTML5 had been gaining ground since the mid-2010s. Unlike Flash, which required a separate plugin, HTML5 runs natively in browsers. Players can start games instantly without installing anything. The technology offered something Flash never could: true cross-platform compatibility. Games built with HTML5 work identically on desktop, mobile, and tablet without modification. By the time Flash shut down, the transition was largely complete.

Platform consolidation around quality

Flash’s death forced consolidation around quality platforms. During Flash’s dominance, browser games were scattered across thousands of small websites riddled with ads. Quality control was nonexistent. Finding a good game meant wading through dozens of broken links.

Post-Flash, platforms that invested in curation took over. Poki, founded in Amsterdam in 2014, built its model around quality over quantity. Every game is tested. Performance matters. The catalog is deliberately selective.

This approach worked. As van Amerongen explained to Mobidictum, Poki now hosts over 1,500 games from 600+ developer partners. The platform features everything from skill-based platformers like Level Devil to racing games like Drive Mad, casual puzzle games like 2048, and mobile hits like Subway Surfers that found a second life on browsers.

To see which browser handles these games best, we tested the best gaming browsers for Windows 11.

Internet speeds increased dramatically. In 2015, the average US download speed was 12.6 Mbps. By 2025, it hit 242 Mbps. Faster connections meant games could load complex assets without frustrating wait times.

Browsers themselves got significantly faster and more powerful. They can now handle graphics-intensive 3D games that would have struggled to run just a few years ago.

Mobile devices became powerful enough to run browser games smoothly. Players could jump into graphically intensive titles on their phones without downloads or storage concerns. If browser games are running slow on your PC, check out how to make browser games run faster.

The new browser gaming ecosystem

Platforms like Poki changed how developers reach players. Instead of scrambling for visibility across dozens of portals, developers could partner with established platforms that handled distribution and player acquisition.

Partnerships with established studios followed. SYBO Games, creators of Subway Surfers, launched browser versions through Poki. The mobile game that had been downloaded over 4.5 billion times found a second life on the web.

Drive Mad has been played over 300 million times. Retro Bowl accumulated nearly 1 million upvotes from players. Smash Karts delivers competitive multiplayer racing that rivals dedicated apps. The gap between browser games and downloaded games has narrowed dramatically.

The technical improvements keep coming. Browsers are getting better at handling high-quality graphics. Game engines like Unity and Unreal now make it easy for developers to create browser versions of their games.

Flash Player’s death didn’t end browser gaming. It forced an evolution that made browser gaming better than it ever was with Flash. The 100 million monthly players aren’t nostalgia traffic. They’re proof the model works.
