So far my solving routine goes something along the lines ofįill in all available numbers in all squares.Įliminate any obvious ones where there's only one possible number in a square. I've been using the 'carpet bomb' approach with some success, but may rethink. Was this written down anywhere? I've been doing the Telegraph puzzles and have so far failed to complete a medium type one (But I think that was because it was the third one that I'd done) and the 'diabolical' on on Friday.

Is it confirmed that the Torygraph's puzzles are Trial and Error? Not that it matters to me that much as I'd never switch from the Times, but it just seems baffling. If The Telegraph want people to solve the puzzles using trial and error then I think they should really print multiple grids in their newspaper. I think the idea of having a Su Doku in the newspaper should be that it can be done without recourse to any other utilities and can be completed on that page with just a pen/pencil.

They are all great methods (although I'd recommend using the excellent Su Doku program available for download on the main page) but they aren't things you can do on the train every morning on your way to work. One final note - I find that if i use the T&E method, i end up making more mistakes that i would without it.

Having said that i intend to get away from the T&E method ASAP. You could use pencil on a newspaper but, i would advise a click style pencil that has a fixed width of lead so as to keep your text nice and small with ease.Īlso you could very easily make up a blank grid template and wither print or copy a lot of pages to keep you busy. I use Excel to draw up the grid so i can use undo to step back where i have tried something out. IF you do end up using trial and error - as i have had to with fiendish puzzles too - there are a variety of stratefies to enable to try things out.
