3Blue1Brown's 'Phone Number puzzle' outpaces the IMO video
Two days old and near half a million views, the week's only upload is gathering views more than twice as fast as a nine-day-old look at the last olympiad problem AI could not crack.

The Phone Number puzzle
Which 3Blue1Brown video is pulling hardest right now? The newest one. "The Phone Number puzzle" went up on September 25, the channel's single upload of the week, and it is already close to half a million views. Its opening day was its fastest, and it has eased since, but it is still moving quicker than anything else on the channel.
The runner-up is not old news either. "The last IMO problem AI could not solve" is nine days old, past two million views, and still gathering a steady crowd. A second video under the exact same title sits further back, moving at a much gentler clip. One question about the International Mathematical Olympiad, two separate uploads, and the busier of the two has well over three times the other's total.
Among the explainers, history and education channels, 3Blue1Brown sits third of nine by subscribers, behind The Infographics Show and freeCodeCamp.org, with Johnny Harris and RealLifeLore close together just below.
