How to beat level 9 of I’m Not a Robot – Select all the squares with a stop sign

Level nine of Neal Agarwal’s I’m Not a Robot game is one of the most demanding stages, pushing you to rely on sharp precision and a great deal of patience. The Nested puzzle asks you to select every square containing even the smallest fragment of a stop sign. The challenge becomes frustrating quickly since missing even a tiny piece prevents progress, forcing you to comb through the grid with care.

Each click on a square subdivides it into smaller ones, revealing more hidden fragments of the stop sign. This expanding grid creates a puzzle within a puzzle, where understanding the exact number of squares to select becomes the key to moving forward. Success comes down to focus, persistence, and mastering the mechanic before frustration takes over.

Here’s everything you need to know about completing level nine of I’m Not a Robot.

Which boxes to select for the Nested puzzle in I’m Not a Robot?

Level nine of I’m Not a Robot takes the concept of a visual puzzle and pushes it to an entirely new level of precision. To clear this stage, you must correctly select exactly 29 squares, each containing some part of the stop sign image. Hitting that precise number is crucial because the game tracks progress based on total coverage, meaning even one missed square or an unnecessary click will prevent completion.

The design of this challenge emphasizes accuracy over speed. The stop sign is broken into fragments that may appear tiny or hidden, but every pixel must be accounted for. The system doesn’t allow for partial recognition as it demands complete coverage of the image across all selected squares. This creates a unique test of observation skills, where patience becomes just as important as sharp eyes.

What makes this puzzle even more complex is its nested grid mechanic. Every time you click a square, it subdivides into smaller sections, revealing hidden portions of the stop sign that weren’t initially visible. This adds a strategic element, as careful clicks can save time and reduce the risk of overlooking essential fragments.

For many players, level nine becomes a real test of persistence. Understanding that there are exactly 29 squares to select helps set a target and provides reassurance that you can solve the puzzle with methodical effort. With focus and patience, this level shifts from an endless clicking trap into a manageable but satisfying achievement.
