Doom, a classic that has endured for more than three decades, continues to captivate players to this day. In fact, enthusiasts have managed to adapt the iconic action horror game onto an astonishing array of devices, ranging from graphing calculators to exercise machines and even pregnancy tests. The consensus is clear: if there’s a screen, it can likely showcase Doom.

In light of this trend, it is hardly shocking that the most recent adaptation of Doom is built for web browsers. Numerous versions to revisit the original Doom online exist, but this particular iteration stands out: it allows players to engage with the game through a CAPTCHA interface.

CAPTCHA challenges serve as a mechanism to differentiate between humans and automated systems, often requiring users to complete simple tasks. The initial forms of CAPTCHAs consisted of typing distorted text—an endeavor that is daunting for robots and, occasionally, even for generative AI tools. Over time, these tasks have evolved significantly, and one of the latest advancements includes integrating a playable rendition of Doom.

Doom Offers an Unexpectedly Enjoyable CAPTCHA Experience

As reported by TechCrunch, this 1993-inspired CAPTCHA was created by Guillermo Rauch, the CEO of Vercel. This organization specializes in AI-driven web development, which Rauch utilized to produce this unique gameplay experience. Join the fun and try it yourself here.

Despite its vintage origins, this web-based edition of Doom is anything but simplistic. Players must eliminate three adversaries before falling victim to them. Utilizing the arrow keys allows movement across the screen, while the space bar is used for shooting. The premise sounds easy, but the intensity ramps up quickly as enemies begin firing the moment you advance.

The high difficulty level can be attributed to the overwhelming onslaught of projectiles coming from all sides. The gameplay unfolds within a confined arena where a cluster of monsters resides, relentlessly launching attacks. Various corridors lead out of this arena, each filled with additional foes, all eager to target you.

Strategies to Conquer Doom: CAPTCHA Edition

Based on a brief session playing the CAPTCHA, three key strategies emerge: First, consistently hold down the space bar to maximize fire output. Doom doesn’t emphasize precision; simply ensure your aim is directed toward the enemies to score hits. Second, bypass the central monsters—their numbers make them overwhelming. Instead, focus on attacking foes positioned in the corridors. The creatures in the cage will shoot at you, and occasionally, they might eliminate some corridor enemies, providing a brief chance for retaliation.

Lastly, consider running around the perimeter of the cage multiple times. It’s impressive how long this tactic can keep you alive while allowing you to witness the central monsters decimate corridor enemies. With some luck, using this strategy might enable you to achieve three kills and succeed in the CAPTCHA challenge. Unfortunately, since you aren’t visiting a dedicated site, the only reward is the victory over this gaming obstacle—but at least you’ve demonstrated your humanity.

As TechCrunch notes, this isn’t even the inaugural instance of Doom being integrated into a CAPTCHA. Miquel Camps Orteza previously crafted a simpler version back in 2021, which limited gameplay to targeting stationary enemies until a kill tally was reached. For those searching for more complexity and higher stakes, Rauch’s adaptation is the superior choice.
