How the 48 levels are put together
The gauntlet is not a random pile of puzzles. It opens with the thing every user on the web has clicked a thousand times — a checkbox — and then spends 47 more stages taking that familiarity apart. Early levels test whether you can click. Middle levels test whether you can see. The late levels test whether you can hold a rhythm, a sequence, or a rolling boulder in your head while a timer runs down.
The difficulty curve also breaks on purpose. Level 34 is arithmetic under pressure, while level 48 wraps things up with a satisfying click. Difficulty here is a texture the game plays with rather than a straight slope, which is why the search filters above are so handy when you hit a wall.
The four difficulty tiers
| Tier | Levels | What it asks of you |
|---|---|---|
| Easy | 8 | One clear action. Read the instruction and do exactly that. |
| Medium | 16 | Careful looking, or a quick rule you need to figure out first. |
| Hard | 15 | Timing, rhythm, or sustained focus. Usually takes a couple of tries. |
| Expert | 9 | Physics, precision drawing, or multi-step logic with zero room for error. |
Puzzle types you will run into

- Memory — 3 levels.

Four golden rules to get you through
- Read the prompt twice. A surprising number of failed attempts happen because of answering the right question incorrectly.
- Take your time on round one. Most timed stages only start the clock once you make your very first move.
- Grab a mouse for the physics stages. Parking, Ikea, and Perfect Circle are noticeably trickier on a trackpad or phone screen.
- Take a break when you get stuck. Din Don Dan and Perfect Circle get much easier after stepping away for a few minutes.
Where your progress lives
The green checkmarks on the grid are powered entirely by your browser. Everything is saved safely in your localStorage, meaning there are no accounts to create, no servers tracking your stats, and zero lag. The catch is that your progress stays on whichever device you are currently using, and clearing your browser data will wipe the board clean.
Got questions? We've got answers
How many levels does I'm Not a Robot have?
There are 48 levels in total. They run from a single checkbox in level 1 to timed physics, memory and audio puzzles in the forties, and each one has its own walkthrough page here.
Which level is the hardest?
The 9 expert stages cause the most restarts — Nested, Parking, Perfect Circle, Parallel Parking, Mathematics, Tough Decisions, Ikea, Floors and Din Don Dan. Perfect Circle and Din Don Dan are the two people most often get stuck on, because neither rewards a second attempt made in a hurry.
Can I play the levels in any order?
Yes. Every stage on this page is self-contained, so you can jump straight to the one you are stuck on. The difficulty curve is not strictly ascending either — level 48 is easier than level 34.
Is my progress saved?
Progress is stored in your own browser using localStorage, not on a server. It survives closing the tab, but it does not follow you to another device or browser, and clearing site data wipes it.
Do I need to download or install anything?
No. Every level runs in the browser on desktop and mobile. Levels built around dragging or precise aiming are easier with a mouse.
