General instructions: In every puzzle some digits have been replaced by letters (from A to J, corresponding to digits from 0 to 9); same letters correspond to same digits and vice versa, also in different puzzles. Some puzzles can be solved immediately (and the letters will be clues), for other you must know the value of some letters. It’s part of the competition to discover which puzzles should be solved first. The list of given letters for every puzzle is shown in the table above
