Click "Show List" to show the list (had to add that because it was buggy) Click the box on the right to submit a seed. NOTE: You can use words, they will just mean absolutely nothing, because I did not code it to transfer words to seed hashes, you will need to turn it into a seed yourself. Click the "Reset" button to reset the list of seeds. You will want to do this if you want to get another seed.
Made for Minecraft Java Historical Version research/speedrunning. Sister seeds are seeds that are similar to each-other in subtle ways. You can find a sister seed by adding 2^48 to a seed that you have. This project was made to find all seeds that are related to an inputted seed.
