An End portal naturally generates without any Eyes of Ender placed in its frames approximately 28.24% of the time.
Understanding End Portal Generation
The End portal is a vital structure in Minecraft, located within strongholds, serving as the gateway to the End dimension. To activate an End portal and enter the End, all 12 of its frame blocks must be filled with an Eye of Ender. When a stronghold's End portal room generates, there's a built-in chance for some of these frame blocks to already contain Eyes of Ender, reducing the number of Eyes a player needs to supply.
Probability of Pre-filled Eyes
The probability of an End portal generating with a specific number of Eyes of Ender already in its frames varies. When we talk about an End portal "without eyes," it refers to a portal where zero Eyes of Ender have pre-filled its 12 frames. While not the most common outcome, it is a significant possibility.
Here's a detailed breakdown of the probabilities for End portal generation based on the number of pre-filled eyes:
| Number of Eyes Pre-filled | Generation Probability |
|---|---|
| 0 (No eyes) | 28.24% |
| 1 | 37.66% |
| 2 | 23.01% |
| 3 | 8.52% |
As the table illustrates, generating an End portal with no eyes is quite common, making it the second most likely scenario after generating with one Eye of Ender. Players finding such a portal will need to craft or acquire all 12 Eyes of Ender themselves to activate it. It's also notable that an End portal can naturally generate with a maximum of three Eyes of Ender already in place; it is impossible for a portal to generate with all 12 frames pre-filled.
