Celebrating 100
The brief
Normal sudoku rules apply. Orthogonally adjacent digits never sum to either 5 or 10. All cages are Split Sum Multiplier cages. In such a cage digits do not repeat and the digits can be split into two sets such that their separate sums multiply to the given clue. For example, a four cell Split Sum Multiplier cage with a 40-clue could contain 1, 3, 4 and 5 (as (1+3+4)5=8*5=40 or (3+5)(1+4)=8*5=40) but also 1, 2, 3 and 8 (as (1+3)*(2+8)=4*10=40).
