I've completed the grid --- this is the one about darts -- and completed the calculation, which leaves 36 to score. To finish on a double requires double 18 which I cannot find within the grid. What am I missing ? Any hints will be gratefully received.
As usual kayakamina you are a star !
Even when writing 1818 the penny didn't drop ; I was so busy trying to find something within the grid itself.
But I'm glad that it caused both of you to look again.
