At midnight last night, the projected time for the 20 millionth puzzle being solved was 04:26:41 on 4th February 2020. This is very close to the cut off point between beaker and mikas.

As before, this is a straight linear extrapolation and does not allow for any trends that might be emerging. If I think of it, I'll post a further update based on puzzles solved by midnight next Sunday.


At midnight last night the projected time has moved forward by around 18 hours to 10:13:02 on 03/02/2020.


Another weekly update and the projected time has moved back to 00:15:46 on 04/02/2020.

I am seeing a lot less 8x8 timed puzzles being done and if it were to continue, I would imagine time would go back a little further ( and I have stopped doing all 13 of the timed puzzles......only reason I was doing them all was to reach 60,000 puzzles plateau for myself)......Am sure other users are cutting back or increasing their timed puzzle solves in order to affect the time for themselves.....but I think either way, it would be too hard to predict just when 20M will be achieved [lol]

I totally agree beaker. The projections are not intended as predictions - they are mere extrapolations of recent results. When we get to mid January, they may become a bit more meaningful, but in the meantime, I find it interesting to watch the ebb and flow.

Hey guys, I've decided to do another experiment to see when puzzle 20 million may arrive. I took 3 weeks of data this time around using the same method as in my previous 10 day experiment. Without further ado, I present my data.

I apologize in advance if these images are too small. Anyhow, I also did some rough estimates of when we'll reach 500K and 250K puzzles left to go. As of 12/1/2019 at 18:00:00 US EDT, there were 19,468,300 puzzles solved according to the ticker on the main puzzle page. Because we're headed towards 20 million, there were 531,700 puzzles left to solve at that given point in time.

500K left to go predictions:

US EDT: Thursday, December 5th 2019, between 9:46:05 and 12:59:02
CET: Thursday, December 5th 2019, between 15:46:05 and 18:59:02

250K left to go predictions:

US EDT: anytime from Friday, January 3rd, 2020 at 5:54:14 to Saturday, January 4th, 2020 at 10:36:29

CET: anytime from Friday, January 3rd, 2020 at 11:54:14 to Saturday, January 4th, 2020 at 16:36:29

What we all want to know, of course, is when we'll have zero
puzzles left to go. Here are my new estimates:

US EDT: Monday, January 27th, 2020 at 3:37:26 to Monday, February 3rd, 2020 at 13:22:05
CET: Monday, January 27th, 2020 at 5:08:10 to Monday, February 3rd, 2020 at 19:22:05

My predictions are only that - predictions. I may very well be in the ballpark or very much away from it when everything is said and done. As expected, there was a solid 1,500 to 2,500 dip in the number of puzzles typically solved per day on Thanksgiving. First off, I'm sure there were tons of people eating, drinking, and partying due to it being a holiday. Secondly, the next day is Black Friday, on which tons of people go shopping (besides maybe recover from hangovers and indigestion). Anyhow, I hope everybody had a happy holiday and take care.
