The transparent window on the £50 note is based on a pattern detailing one of the huts at Bletchley Park.
We found an encoded message scribbled under one of them.
Give it sum thought, and see if you can make it add up.
If you look at it from a different angle you should see a Welsh town through the window, which would be a real plus!


CORWEN ¬- The six colours all represent digits, which can be summed along rows and columns to give the totals around the edge. These are then swapped alphanumerically for letters. The digits can be found by solving simultaneous equations; and from lightest to darkest represent the values: 1, 6, 7, 3, 2, 8.
Summing along the rows gives:
3, 15, 18, 23, 5, 14 = CORWEN
