Dear 43 Things Users,

10 years after introducing 43 Things to the world, we have decided we have met our last goal: completing the incredible experience that has been 43 Things. Please join us in giving one last cheer to all the folks who have shared their goals with the world, as well as all the people who have worked at The Robot Co-op to build this incredible website. We won a Webby Award, published a book, and brought happiness to a lot of people.

Starting today, 43 Things users can export their goals and entries from the site. Starting August 15, we will make the site “read only”. 43 Things users will still be able to view the site and export their content, but we won’t be taking any new content from users. We hope to leave the site up for folks to see and download their content until the end of the year. Ending on New Year’s Eve takes us full circle.

It has been a long ride (one of our original goals was to "build a company that lasts at least 2 years” - we beat that one!) While we wish the site could live on, it has suffered from a number of challenges - changes in how people use the site, the advertising industry, and how search engines view the site. We wish the outcome was different – but we’ve always been realistic about when our goals are met and when they aren't.

As of today, you will be able to download your goals and entries. See more about that on the FAQ page. Thanks for 10 great years of goal-setting and achieving.

LestatEmpireLevel 80

This level requires me to go back to all the previous pages and look for girls. Quote: “Only all those chicks can help you now!” 7 years ago


I think I’m going to cry. My browser or whatnot won’t let me get past Level 76. I went through all the sublevels and reached the last one. Had to change something in the address bar, and I know what the u/p are. But do I use capitals where necessary? Non-capitals? All lower-case? cries Error 401 and 404 pops up. 7 years ago


Now up to Level 72. I had to call up a friend who is a wiz with audio manipulation though. I need a rest. 7 years ago

Too much computer knowledge required for this. Takes up waaaaay too much time. Maybe in a hundred years I’ll try this. 7 years ago


Why did I choose to do this?? Honestly, my mind does not have the capacity to cope with those riddles. I-am-slowly-going-insane.

Stuck on level 7, and I only got past 6 by cheating, anyway. Pfft. 7 years ago

LestatEmpireOh boy

School’s started again, so I might be able to squeeze in an hour/day for NotPron. Then I’ll just fail this year. 7 years ago


i started the puzzle an hour ago after seeing it on this site im on level 6 now i think but struggling to under stand how alt and anogram can be combined…. guess i need to do more research on alt or relax and see if its simpler than i think it is….. just a break would do ha x 7 years ago

josiah668A new drug

Today I got snowed in and didn’t have work. Instead, I spent nine hours getting addicted to Notpron. I made it as far as level 16 before my friend and I decided to call it quits. And I’m still thinking about it. What the hell do they mean by invert? I’m sure I’ll get it eventually.

Whatta game. 7 years ago

wieboldThe right place to lose time and possibly your mind...

Whoever did this riddle-game – he/she is a genius!

I love the sometimes twisted logic in the riddles – however, right now i’m stuck on level 24 (of ca. 160) – seems I’m to dumb (grin).
