Brain Teasers are Back!

I’m planning to give it a go.

I found this one quite relaxing Mike. Hope you do too.

Hi Don,

that was just the right thing for yesterday’s evening. We’re currently remodeling our living/listening room and the teaser was perfect to relax wind down.

Great, Thank you.

Hope Mike enjoys it as well !

Wheeler Dealer

Lots of numbers and a “?” mark !

Simply replace the “?” with a number that meets the conditions of the wheel !

Warning !

This is easy, but not as relaxing as the dominoes !!!

Triangle Numbers

What is the missing number (?) in triangle D ?

PS. I think this one is a lot easier than the Red Disc above, and it might provide some sort of insight to the Red Disk !

Red Disc missing number is 4 (inside number is the product of the two outside numbers in the next but one segment to the left ie 5 x 4 = 20).
Red triangle missing number is 7 (inside number is twice the sum of the outside numbers).

Nicely done Steve.

That Red Disk just needed a bit of “lateral” thinking ! (it took me a while when I first saw it)

Numbered Tiles Square

The numbered tiles will fit together to form a square in which the numbers in the top row match the numbers in the left column. The numbers in the second row down match the numbers in the second column from the left. And so on !

Makes a change from tiling the bathroom !

Transport Spreadsheets

Each symbol has a value. Can you find the worth of the question mark ?

? = 39

Plane = 9
Train = 6
Bike = 3
Boat = 24

Thanks, the brain teasers with visual patterns work well for me, some of the items you post my brain just starts to hurt looking at them!

Hi Seakayaker, I know the feeling !

If you’re looking for a seemingly simple teaser, try the “goat in a circular field” one early in this thread, about post 23 and repeated about post 68. Looks dead simple so shouldn’t hurt the old brain !

Then have a look at the explanation starting at about post 75. This is when the old grey cells start wobbling and the headache begins …

The ink wasn’t dry !

Well done !

Don, from your ‘numbered tiles square’ post 2 days ago.
