I'm slightly annoyed with myself. Sometimes I do the puzzle just after midnight, on the ipad, whilst lying in bed. Sometimes I do it on my PC. That means that I have two different score records. I normally transfer from ipad to PC but I have clearly forgotten because according to the PC I've only got a winning streak of 2.
I think I'm up to no 28, having failed at my first attempt but succeeded in every one since. Perhaps I should set up a spreadsheet...
PS I put the words I have chosen in spoiler tags just in case I want to go back and look later. Otherwise I don't see much point in posting the coloured squares.
