Hello,

Welcome to mcseedmap.net, an easy way to view, discover and share Minecraft world seeds!

Q&A

What is a seed?

A Minecraft world seed is a unique number or string of characters that is used to initialize the random generator when creating a new world in Minecraft. This seed determines the layout of terrain, structures, and other features in the world. The same seed generates the same world every time, allowing players to share seeds to explore the same world or create specific landscapes.

What is a seed map?

A Minecraft seed map is a visual representation of a Minecraft world generated using a specific seed. It shows the layout of terrain, biomes, structures, and other features of the world, allowing players to preview what the world will look like before actually creating it in the game. Seed maps can help players choose interesting or desirable worlds to explore or build in.

How accurate is it?

Biomes are pretty accurate. Note that the actual shorelines of rivers and oceans do not follow biome boundaries exactly.

Structure positions are accurate to within a few blocks, but some structures may be missing, and there may be structures that are not generated in the game.

Java structure finding is more accurate than Bedrock because there is more information available about the algorithms.

Spawn positions can be completely wrong for some seeds. Java spawn estimation is more accurate than Bedrock.

Is it cheating?

While using a seed map can reveal the locations of biomes or structures like End Portals without the need for exploration or Ender Eyes, whether it's considered cheating is subjective and depends on the player's perspective. Some players enjoy the challenge of finding structures through exploration, while others prefer to use tools like seed maps for convenience. Ultimately, it's up to each player to decide what they consider fair or enjoyable in their gameplay experience.

Are Java and Bedrock seeds the same?

Since Minecraft version 1.18, seeds generate the same terrain and biomes on Java and Bedrock editions, but trees, grass and structures will be different.

Why is the map not loading?

Pro tip! If you are more serious about seeds, need high performance and advanced seed finding features, the open source Cubiomes Viewer desktop app is for you.
