A typical size is around 9-15 cells square. Kakuro puzzles originated in the US about 50 years ago under the name "cross-sum" puzzles. In Japan they have become known as 'kakro' puzzles, and in the U.K. we have anglicised that name to get kakuro.

Springer, Berlin (1996)Booklet of Midi Su Doku Puzzles (8 puzzles on 6x6 grids) suitable for secondary school children aged 11-13. [ Answers] Tip 1: Look for rows, columns of 3×3 sections that contain 5 or more numbers. Work through the remaining empty cells, trying the numbers that have not been used. In many cases, you will find numbers that can only be placed in one position considering the other numbers that are already in its row, column, and 3×3 grid. In addition, there is a “double” tactic. This tactic is characterized by the fact that in a row, column, or in a small square, you can still place only two possible numbers. But you do not know which one to put. The idea is that you make a mark about it and exclude it from further decision. This reduces the number of options to solve, and it becomes easier to solve the puzzle. The same can be done for three digits. This tactic is called a “triplet” or “triple”.
