A very addictive puzzle that is great for building logical thinking whilst reinforcing basic maths skills. Three thumbs up!
Apologies - this is not a digital resource, but it is such a wonderful puzzle that I just had to include it.
I lived in Eugene Oregon in the summer of 1980. A local newspaper had a wonderful weekly puzzle column, so each week I would buy the newspaper and go to a coffee shop and attempt to solve that week's puzzle. The link below is my favourite puzzle from that era.

Your task: Answer the question below. Then download and open the attached Excel spreadsheet. The number of legs is the password to unlock the Excel sheet. Add your name to the spreadsheet and send it on to see who else can unlock it.
Note: This is not a trick question. This is a real math problem so don't say that a bus has no legs. Also, there is no driver on the bus, so don't add any legs for a driver.
There are 7 girls in a bus
Question: How many legs are there in the bus?

Peg Solitaire (also known as Hi-Q) has very simple rules. Pegs (red circles in this implementation) are allowed to jump over adjacent (vertically or horizontally) pegs. The peg that has been jumped over is removed. So jumps are like captures in Checkers. To move a peg, you select it first by clicking on it once. Then you click at the square (hole) to which you want the peg moved.
Use logic (ie your BRAIN) to drop the ball over the correct tools in the correct order.
The 16 Scaredy Cats are sleeping, in a 4x4 grid. They'll wake up when you click them. And they'll be scared - if you click on "Mice!! Hide!!" they'll run off and hide!
You and the computer will take turns teasing these poor Scaredy Cats. But you don't want to be left scaring the last cat. If you're stuck with the last Scaredy Cat, you lose.
You can wake up from 1 to 4 neighbouring cats in the same row or column. Click "Mice!! Hide!!" to scare them off. Then the computer will take its turn and more cats will run off.
This is quite a challenging puzzle - Good luck!
