Not a weekend puzzle, but a riddle: You can draw a triangle with three lines. Now draw a square with three lines. (Thus not four lines.) Adri If I read the challenge correctly then that’s easy :-) |

Solution to the short riddle ("Draw a square with three lines."):
It is hard to draw a square or some lines here, IYKWIM, so just interpret as a square with three lines, please.  Adri |

Dear weekend quiz participants, especially alanb1951 and Sgt.Joe,
----------------------------------------The answer to the puzzle that was presented in post 707848 … Answer: 4862 There are four unique characters in each 'grid' of nine symbols: % = $ + The 'cells' in the 3x3-grid can be numbered as follows: 1 2 3The numbered cells in the grid correspond to the 4-digit number on the right. So, according to the first grid and its 'result', 1265, the value of the % is 1, the = is 2, the + is 6 and the $ is 5; this is also the order of the symbols: % = + $. In the second grid, 5324 also corresponds to the same order of symbols: % = + $ It is no wonder that we have the same symbol order in the third grid: % = + $, corresponding to 7426. So, the fourth grid tells us that % = + $ results in the answer 4862. Thanks for playing! Adri [Edit 2 times, last edit by adriverhoef at Dec 4, 2025 1:30:59 PM] |

Adri: nice explanation.
 Bryn Mawr: as you said, "clever"  -- I looked at it for a few minutes puzzling about arithmetic (and thinking "No way..."), then had a lightbulb moment  Once again, thanks to Adri for the puzzle! Cheers - Al. |

It's 12:30 local time in the Netherlands on a Friday and 00:30 on a Saturday in Auckland, New Zealand, where the weekend has already begun.
This is the new weekend puzzle, for the young and for the old: 'Like father like daughter' A team member has a daughter who's 50 years younger than he is. They both have a computer that is crunching for World Community Grid. Five years ago, his daughter bought her current computer. At that time, her father was three times as old as she was. What's the age of the female member now? Good luck pondering the question! Adri |
