In the following diagram, each red dot represents a positive number. The dot-numbers on each of the five circles spell out either a word (each dot corresponding to a letter) or a number (each dot corresponding to a single digit), always starting at the topmost dot and moving around the circle clockwise. Your task is to find these five words or numbers and put them together to get a solution.
In order to solve the puzzle, you are provided with the following information.
The numbers in each region: regions created by the circles and diamond, plus two extra lines to split the pairs of red dots which share the same circular arc, and one more line for symmetry. Each of these numbers is the sum of all the red dot-numbers on the border of that region. For example, the topmost 5 is the sum of the two topmost red dots, and the 7 is the sum of the three next red dots below them.
The same information is also provided for the two-circle overlap regions. I haven't included these in the diagram because it would confuse things, but here are the numbers which would be in the regions between each pair of overlapping circles:
- In the region between the top two circles (the 7 and 15 regions combined): 12.
- In the region between the first and third circles (the 15 and 21 regions combined): 32.
- In the region between the second and third circles (the 15 and 25 regions combined): 24.
- In the region between the third and fourth circles (the 40 and 24 regions combined): 28.
- In the region between the third and fifth circles (the 27 and 24 regions combined): 41.
- In the region between the bottom two circles (the 24 and 38 regions combined): 60.
Since the number at the centre of the middle circle is a sum of five red dot-numbers, not just two or three, you can have the numbers themselves (not in order) as well as their sum: 4, 4, 7, 11, 21.
