To unlock the lets not achievement worldbox mobile, you must use the Acid Power to cover over 90% of the map in the Wasteland biome on a small map. Using only the finger power will not trigger the achievement, as the game specifically requires biome coverage from the Acid Power.
How to unlock the let's not achievement in worldbox mobile
Follow these exact steps to unlock the achievement on your mobile device:
- Start a new world and select a small map size. This makes reaching the required coverage much faster.
- Open your powers menu and select the Acid Power.
- Apply the Acid Power repeatedly across the entire map. Keep applying it until the vast majority of the map shows the Wasteland biome.
- Continue until more than 90% of the map is covered in Wasteland. The achievement will unlock automatically once the threshold is met.
Do not rely on the finger tool or any other destructive power. Only the Acid Power's biome-changing effect counts toward this achievement. If you want to explore other ways to alter your world, you might look into mobile game cheat codes, but for this specific achievement, the Acid Power method is the only documented working solution.
Why the finger power method fails
Many players try using the finger tool to destroy the map, but this method will never unlock the achievement. The achievement is tied specifically to Wasteland biome coverage created by the Acid Power. The finger tool damages terrain and entities, but it does not change the underlying biome to Wasteland. Even if you destroy every tile on the map with the finger tool, the biome coverage requirement will not be met, and the achievement will not trigger.
Tips and strategy for faster results
The most effective strategy is to start on a small map. A small map requires far less Acid Power application to reach the 90%+ Wasteland coverage threshold. On larger maps, the process takes significantly longer and requires more patience. Apply the Acid Power in sweeping motions across the map, focusing on areas that have not yet converted to Wasteland. Check your map periodically to see how much of the terrain has changed. Once the map is overwhelmingly Wasteland, the achievement will unlock.
Let's not achievement rewards
Unlocking the let's not achievement rewards you with three traits for your worlds:

These traits can be applied to creatures in your world, giving them resistance to acid damage or the ability to inflict acid damage on others. WorldBox has 86 mobile achievements.
Frequently Asked Questions
Does finger power work for the let's not achievement?
No. The page specifically states that using only the finger power will not trigger the achievement. You must use Acid Power to change the biome.
What biome is needed for the let's not achievement?
The Wasteland biome is required. The achievement is tied to covering the map in Wasteland, not just any destroyed terrain.
How much of the map must change to unlock the achievement?
Over 90% of the map must be covered in the Wasteland biome. Stopping before this threshold will leave the achievement locked.
Can I use explosions or other destructive powers instead of acid?
No. The documented requirement is specifically Wasteland biome coverage from Acid Power. Other destructive tools and explosions do not create the Wasteland biome and will not count toward the achievement.
Does the map size matter?
Yes. Starting on a small map makes reaching the 90%+ coverage threshold much faster and easier. Larger maps require significantly more Acid Power application.
