Hi Cheshirecrone and Blackcat,
Yes, 225 is shorthand for the site fifteensquared.net. It differs to here in that it publishes daily blogs (clue by clue analysis) of all Guardian, FT, Independent, Observer puzzles and a few others. For prize puzzles the blogs are only published after the closing date for the competition has passed.
Two other sites to note⦠blogs for Times puzzles are covered on TimesfortheTimes and for Daily Telegraph puzzles on BigDave.
Hope that helps.
