What Is This Achievement?
The “Chestful of Cobblestone” achievement (on Bedrock Edition) unlocks after you:
- Mine 1,728 cobblestone blocks (which is 27 full stacks)
- Place all of them into a single chest (not a double chest!) (You may try on a double chest too)


Step-by-Step Guide
✅ 1. Mine the Cobblestone Yourself
The achievement only works if you personally mine all 1,728 cobblestone. Any blocks obtained via trading, creative mode, or commands will not count.
✅ 2. Use a Regular Chest
Use a single chest, not a double chest. Place 27 stacks of 64 cobblestone inside. That’s exactly 1,728 blocks.
✅ 3. Survival Mode Only
Make sure you’re playing in Survival Mode, with cheats disabled. If cheats are on or you’re in Creative mode, achievements won’t work.
✅ 4. Wait a Bit
After filling the chest, wait a few minutes. Some players report a short delay before the achievement pops.
✅ 5. Reopen or Restart
Try closing and reopening the chest, or even restarting the game. Sometimes, this forces the game to recognize the achievement.
Still Not Working?
If you’ve tried everything above:
- Make sure you didn’t accidentally use a double chest
- Double check that you mined the blocks yourself
- Try doing it again with freshly mined cobblestone
