Hey guys, I accidentally stumbled upon this really neat math puzzle. Really enjoyed it a lot and I'd say it's certainly the hardest and most fun math puzzle I ever encountered (not that this necessarily means much though )
Anyway, I thought some people here might also enjoy it so there you go. Explanation is in the first 3:30 afterwards the solution(s) are presented, so be sure to stop (though the guy in the video will remind you too, so don't worry about keepng an eye on the timer)

Have fun and let me know how it went
p.s. I solved all except for the ones and zeros. Though I regret giving up at that point, I'm sure sooner or later I MIGHT'VE figured out the ones at least
