    As the title said.

    It has come to my attention that so many pages are being linked to nonprime pages, which defeats the purpose of linking the prime numbers together in the first place. Remember this is a prime numbers wiki, and therefore it is even debatable if the composite numbers should be kept in the first place, which makes the link changing into composite numbers even more problematic.

    I appreciate the effort to link pages throughout the wiki, but it is much more practical if we are linking prime numbers together and not making troubles with composite numbers. If desired to make these pages about numbers as well, you should go to the Numbers Wiki.

    If problems continue to occur, I might have to block users. I would give a warning linkin…

    Hi, everyone!

    This is a One-Off Question Of The Day because I found a question that I thought would make a good Question Of The Day.


    A prince is sent to jail and locked up in a tower. The guard takes pity on his and gives him a chance to escape being hanged

    The guard gives the prince two boxes. One contains 50 blue marbes and the other contains 50 red marbles. He will wear a blindfold and pick a marble out. If it is blue, he'll help the prince escape. If it is red, the prince will be hanged. The guard tells the prince that he can rearrange the marbles any way he likes, but he has to use all the marbles.

    After a night of rearranging the marbles, he manages to increase his chances of surviving to almost 75%. How did he do it?

    Hi, everyone!

    As the wiki doesn't seem to be alive anymore, the Question of the Day (Week) may not be continued further. Since I am starting to get busy, I am likely to be inactive on this wiki in the future. Therefore, I may not be coming up with a lot of questions for the next few weeks.
