As soon as it is activated, the portal destroys all blocks in the central 3×3 square, including bedrock or another portal frame, and replaces them with the end portal blocks that can teleport an entity into the End dimension. Once all the eyes of ender are placed, the portal activates and emits a loud noise. Each frame block has a 10% chance of generating with an eye in it already, meaning the player may not necessarily use 12 eyes to activate it. The player can activate the portal by filling the 12 end portal frames each with an eye of ender. A silverfish spawner sits on top of the staircase. The portal hangs over a lava pool, with a staircase leading up to it. The room consists of a 5×5 square of end portal frames, with the corners cut out, making a total of 12.

To access the End, the player must go through the process of finding a stronghold using eyes of ender, finding the portal room, and activating the end portal in the end portal room.
