I don't know about any other UK reader of these forums, but I for one miss the old Keesing "Arrownumbers" puzzles, which are exactly the same as Kakuro but with the added feature that each combination can only occur once per puzzle; e.g. if one 8 in two digits is 17, and there's another 8 in two, it must be 26 or 35.
To my mind, this made Arrownumers a lot more interesting to solve than Kakuro.
