CAPTCHA demands pathfinding skills worthy of a senior gameplay engineer
Description
The screenshot shows a CAPTCHA-style challenge with the instruction, "Use the arrows to move the train to the coordinates indicated in the left image (1 of 6)." On the left, a grainy black-and-white thumbnail labeled "Train Position" shows a rail yard and the number "7" over a pixelated train car icon. On the right is a 10×10 grid map overlaid on tracks; household-item icons line the top, and two large arrow buttons sit on either side for navigation. A pagination indicator (six dots, first one highlighted) sits below, followed by a dark "Submit" button and a long hexadecimal tracking string "762176453ee555d92.4999930301." Audio and Restart icons occupy the footer. The visual humor comes from the absurd complexity - six stages of grid navigation - illustrating the security-vs-usability gulf engineers routinely lament when CAPTCHA designers turn login into a mini RTS path-finding exercise

When your CAPTCHA requires A* search, you know the security team just discovered game-dev pathfinding algorithms and couldn’t resist a production rollout
We've successfully trained our ML model to solve CAPTCHAs, but now we need a second model to solve the CAPTCHAs that protect the first model's training data
Ah yes, the modern CAPTCHA: proof that we've successfully trained humans to solve increasingly complex puzzles to prove they're not robots, while actual ML models trained on CAPTCHA datasets laugh in 99.8% accuracy. This six-step train-positioning nightmare is what happens when security teams discover game engines but forget about user experience - because nothing says 'legitimate user' like someone willing to spend five minutes playing a coordinate-matching minigame just to submit a form. Meanwhile, the bots are already inside, having exploited the API endpoint that doesn't check for CAPTCHA tokens
When your login gate requires pathfinding a toy train to coordinate 7, that’s not bot defense - it’s security theater that 403s humans, breaks Selenium, and gets solved by a cheap API faster than the page loads
Nothing says bot protection like a six‑step A* on a canvas - great at locking out customers, trivial for a script with OpenCV and a heuristic
