No answers, thanks.
(but do tell us how you got on) |
|
Done, 3 minutes
|
|
Yes. Thanks for the distraction
|
|
Done, a nice little diversion. Now to explain how to do these kind of puzzles to my kids.
|
|
Done. More than 3 minutes.
Thanks. |
|
I enjoyed doing this, a nice distraction from the current situation. Thank you for it. Took me about 10 mins.
|
|
Yes, that was fun.
Took me longer than it should have! |
|
Eight simultaneous equations with four unknowns. Pretty. If it is not too much of a hint: <snip> |
|
Nice puzzle, thank you. Had to recreate it in a spreadsheet to work out, took about 5 mins.
|
|
While solving it I was aware that the number of simultaneous equations is over-generous, so thought there must be a more elegant method than the plodding one I used.
I get that feeling often when doing sudoku. |
|
Glad it wasn't just me who worked it out using simultaneous equations!
Needed that bit of mental gymnastics to wake my brain up. Today has been rather boring thus far. |
|
I also solved it with simultaneous equations.

|
Some sets of four differ by only one colour, and one <snip>. QED
|
|
I have no idea about simultaneous equations, so lacked the 3-minute ability, but being a visual person I rearranged the squares in a spreadsheet looking for more obvious patterns - probably much as Jeremy.
Nice puzzle thanks - could be the makings of a moquette too. |
|
Straightforward.
Took me about five mins in my head. |
|
I wasn’t able to do it in my head but found it quick enough once I wrote down my observations.
