Unsurprisingly, it was exactly what I thought.

Well done. Apparently its proving to difficult for the majority of people trying it.

The solution is just to make a table with, say, month as the rows and numbers as columns. After that you can use known details to remove rows/columns (in our case, mostly rows) to see what is left.

I wish I was better at this type of logic puzzle.

Nah, I just had a book that described ways to solve this kind of logic puzzles. The one with the table is the easiest.

It's frustrating, isn't it? UK schools just don't teach that kind of logical process. We're taught how to apply formula A to problem B, using a tool as told to by a teacher rather than actually thinking about the question.

Lord Ba'al: He is indeed at it again. I read a few lines from some article saying he took something from this game and something from that game and something from yet another game and put it all together. Aug 21, 2024 17:34:06 GMT

Lord Ba'al: Then it mentioned there was this big hand mouse cursor, and I was like, nah, this will be shit. Aug 21, 2024 17:34:25 GMT

Lord Ba'al: Initially it was promising though, as it mentioned he had "put the old band back together". Aug 21, 2024 17:35:05 GMT

Lord Ba'al: By the way, I closed the whole forum for posting, due to the fact that all that was being posted was spam, but if anyone wants to make a post, I'm happy to open it up again, even if that's maybe just temporarily. Aug 21, 2024 17:36:02 GMT

Lord Ba'al: Or... post in the spammer section, and I can always move it elsewhere
