This puzzle is a chaos construction: you must determine 9 orthogonally connected regions and fill them with the digits 1-9.

Cages indicate the product of each region sum contained in a cage. For instance, if a 4-cell cage contained 1,2 in one region and 3,4 in another region, its total would be (1+2)×(3+4)=21. Cages may be contained in one region, in which case, the total is just the sum of the cells. Digits may not repeat in a cage.
