# 33

Fill the grid so that each block of squares – horizontal and vertical – adds up to the figure total in the grey box above or to the left of the block. You can only use the numbers 1-9 (not all the numbers though) and you must not use the same number twice in a block. The same number may occur more than once in a row or column, but it must be in a separate block. If, for example, there are two squares in a block and the total marked above it is a 6, then the possible solutions for those squares are 15, 51, 21 and 42 (33 is not a possible solution because it uses the same number twice).
