A miserable day for me , only had two letters by Third row , three on fourth, but all in correct places , then there were TOO many options.
It was the the correct place on the second row that did it, which made it very likely to be CCVCC rather than CCCVC or even less likely CVCCC given the three letters I had.
Lucky to get it by the fifth line ! Only had three letters by third row and none were placed in the correct position. Didn't have a clue on fourth line... Was getting very close to chucking an early morning wobbly hissy fit , then a light bulb moment ! I got it , from four , none correct 0 position's !!!
