Level 21 of I’m Not a Robot breaks away from the usual captcha-style puzzles and drops players into a crafting challenge that feels straight out of Minecraft. Known as CRAFTCHA, this stage requires you to create a Diamond Pickaxe using limited resources. If you’ve played Minecraft before, the recipe will feel instantly familiar. If not, don’t worry—this guide explains every step in detail so you can clear the level smoothly.

At the start of Level 21, your inventory contains:
- 2 Oak Logs
- 3 Diamonds
The crafting grid mirrors the classic Minecraft 3×3 setup. Your goal is to transform these raw resources into the necessary components for a Diamond Pickaxe—sticks and diamonds arranged in the correct pattern.
Step 1: Convert Logs into Planks
- Drag the Oak Logs into the crafting grid.
- Each log breaks down into 4 Oak Planks, giving you a total of 8 Oak Planks.
- Move the planks into your inventory for later use.
This step mirrors the basic resource transformation in Minecraft, where logs are your foundation for almost every tool.
Step 2: Make Sticks
- Place two Oak Planks vertically in the middle column of the grid.
- This produces 4 Sticks.
- You only need 2 Sticks for the pickaxe recipe, so keep the extras aside.
The sticks will serve as the handle of your pickaxe.
Step 3: Assemble the Diamond Pickaxe
Now comes the crafting recipe itself:
- Place one Stick in the center square of the grid.
- Place another Stick directly below it in the bottom middle square.
- Arrange the three Diamonds across the entire top row of the grid.
Once everything is in place, the familiar shape of a pickaxe appears. The output slot will reveal your freshly crafted Diamond Pickaxe.

What Happens Next
After successfully crafting the pickaxe, you’ll clear Level 21 and move on to Level 22: My Ducks Ahh, where the challenge shifts again into another quirky captcha test. With 48 levels in total, this is just one of many unique puzzles designed to keep you guessing and laughing.
- Think Minecraft logic: The recipe is identical to the original game, so use that knowledge if you’re familiar with it.
- Don’t overcomplicate: You only need 2 sticks and 3 diamonds—no extra steps beyond planks and sticks.
- Stay precise: Misplacing even one diamond or stick won’t trigger the recipe, so double-check your grid layout.
Crafting the Diamond Pickaxe in I’m Not a Robot is a clever nod to one of gaming’s most iconic mechanics. Whether you’re a longtime Minecraft player or new to crafting puzzles, this stage blends nostalgia with problem-solving in a way that makes it one of the most memorable levels in the entire game.
