**HEXAGON-numeric (basic)**

Fit the numbers 1 – 6 in each hexagon. Where the sides of different hexagons meet, the adjoining segments will have the same number value. No number can be repeated in a hexagon.

### Solution

**HEXAGON-numeric (intermediate)**

Fit the numbers 1 – 6 in each hexagon. Where the sides of different hexagons meet, the adjoining segments will have the same number value. No number can be repeated in a hexagon. The numbers in the shaded areas are the sum of the numbers in the 2 or 4 segments that they adjoin. The numbers in the ‘Input’ and ‘Output’ boxes are the sum of the numbers in the 3 triangular segments that they side with. Solve the puzzle and find the ‘Output’ number (?).

Hi Gordon,

I have prepared an hexagon puzzle for my granddaughters which I cannot solve myself… Each hexagon is divided in three equal parts that bear different colors, out of a choice of 6 colors. I have printed hexagons with all the possible variations (including mirroring ones, for example blue-yellow-red vs blue-red-yellow). I came up with 40 different hexagons. While trying to connect them matching the color edges I have never managed to fit them all in one design. Any suggestions?

Great idea! Did you manage to find a solution or proof for this I wonder?

Hi Yehuda

Send me a copy or copies of your hexagon puzzle and I will provide my comments.

It sounds interesting.
