## Can you solve it? Give your grey cells a party with the Sweet 16 puzzle.

Place the numbers from 1 to 16 in the grid below so that they obey the horizontal and vertical equations.

The circles are odd numbers and the squares are even. We’re given the ‘1’ as a start. Now use basic arithmetic to fill in the rest. It’s helpful to have a physical copy of the puzzle, so click here for a printable version.

Sometimes I get complaints that my Monday Puzzles are too easy. You know who you are, and this next one’s one for you. Again, the numbers from 1 to 16 are used once each, with circles odd and squares even. This time there is a ‘greater than’ symbol too.

Oh geez.

This puzzle is NOT easy.

You saw the third puzzle??

Yes! Ridiculously hard even though there's only 3 places 16 can go.
