Step-by-Step Solution
Step 1: Create Oak Planks from Wooden Logs
Locate wooden logs in your inventory and drag one into any slot of the 3x3 crafting grid. The system automatically converts the log into Oak Planks in the result box.
Step 2: Craft Sticks from Oak Planks
Place Oak Planks vertically in the crafting grid: one in the center slot (middle row, middle column) and another directly below it (bottom row, middle column). This produces Sticks in the result box.
Step 3: Assemble the Diamond Pickaxe
Place two Sticks vertically in the center column (middle and bottom slots). Then place three Diamonds horizontally across the entire top row. The completed Diamond Pickaxe will appear in the result box.

Common Mistakes to Avoid
- Skipping intermediate steps: Cannot place raw logs directly in pickaxe recipe
- Incorrect stick placement: Sticks must be vertical in center column, not horizontal
- Diamond arrangement: All three diamonds must occupy the complete top row
- Material shortage: Need at least one wooden log and three diamonds
Pro Tips
- Follow crafting hierarchy: Raw materials must be processed into intermediate components first
- Pattern recognition: Diamond Pickaxe follows same pattern as other pickaxes with different materials
- Use result box feedback: Correct patterns show desired item immediately
- Clear and restart: If placement errors occur, clear grid and start over
Frequently Asked Questions

Q: Can I use different types of wood or materials?
A: Use only the wooden logs and diamonds provided in the inventory. System may not recognize substitutions.
Q: Do I need prior Minecraft experience?
A: While helpful, following this guide's step-by-step instructions enables anyone to complete the challenge successfully.
Summary
Successfully completing Level 21 requires methodical progression through Minecraft's crafting hierarchy: converting wooden logs to Oak Planks, crafting Sticks, and assembling the Diamond Pickaxe using the correct pattern of three diamonds across the top row and two sticks down the center column.
