Cumulonumbers

(Eingestellt am 1. Oktober 2025, 11:11 Uhr von ThePedallingPianist)

This is my response to Scojo's setting prompt as redeemed by ChinStrap, which was to make something inspired by a puzzle from this year's Imposter Series. I chose Sumflake by MathGuy_12. Honestly it was a fairly loose inspiration - a pun combining a weather phenomenon with a mathematical term - but nevertheless I recommend that puzzle!

Many thanks to Marty Sears and ViKingPrime for help with aesthetics, and to Justin V for testing.

Normal sudoku rules apply.

Box borders split blue lines into segments whose values have the same sum.

The value of any cell containing cloud is the cumulative total of all digits in that cloud in normal reading order, up to and including that cell. For example, the value of r2c4 is r1c4 + r2c3 + r2c4.

Lösungscode: Row 1 (top), left to right

This was a beautiful puzzle. Like others in the comments, I found the mid-solve very tricky, especially in box 6: it was definitely 3.5-4* for me there. But very beautiful logic once you spot it :)

Enjoyed this even though I got stuck a couple of times, fairly tricky but good!

This was fantastic! Excellent rainteaser. I found it easy and intuitive to get my head round how the rule worked, but hard to actually spot many of the deductions. SO fun though, and very slick throughout. Every time I did eventually spot the way to progress, it was like a mini eureka moment, coming with a nice feeling of achievement. There was a certain moment in box 8 that I found particularly pleasing.

Really love how you made the clouds look, and the theming and title... it all comes together perfectly

Delightful opening. But in the mid solve a heavy storm caught me. Very tricky steps there to me. Rather 3.5-4* to me. But great math interactions. Very clever setting thx.

Super elegant opening, very satisfying how it all works out! And an excellent job on the visuals! Happy to be a loose inspiration for this one

Like dealing with any inclement weather, all it takes is some careful preparation and a little planning ahead, and math (though you and I may deal with weather differently).
