Secret seeds in 1.4.5 are world modifiers. They do not just reroll terrain, they can reshape the surface, change visuals, or alter how the run plays. Start with Skyblock for a real challenge, then try Dual Dungeons, Planetoids, Mole People, and Waterpark for worlds that feel instantly different.
When you create a world, type a seed into the Seed field. You can enter either:
the seed code (example: noSurface)
the seed phrase (example: mole people)
Capitalization and spacing are not important. If the seed is accepted, the game confirms it during world creation.
In 1.4.5, once a seed has been entered at least once, it becomes easier to reuse from a secret seed menu during world creation. Many of these modifiers can also be stacked, so start with one at a time if you want predictable results.
Type: Special seed
What it does: You spawn on small floating islands with limited resources. Progress comes from bridging out, expanding carefully, and making every block count.
These are the 35 secret seeds introduced in 1.4.5, shown as phrase, code, and the practical effect.

If you want a world that looks different immediately, try monochrome, negative infinity, invisible plane, or rainbow road.
If you want exploration to feel unfamiliar, try dual dungeons, mole people, such great heights, or planetoids.
If you want a run that changes how you play, try too easy, random spawn, vampirism, or night of the living dead.
If you want chaos for building and screenshots, try waterpark, then stack it with a visual seed.
