Apply classic Sudoku rules : Each row, column and bold-outlined region must contain the digits 1-9 once.

Furthermore, cages, represented by dotted areas, must contain digits that add up to the total in their top left corner. Digits musn't repeat wothin a cage.

• The grey cells in the puzzle have their values halved in regards of the cages's sums (e.g. a grey 8 is counted as 4 for a cage). For odd numbers, they are rounded up to the closest integer (i.e. for grey cells, 1=1; 3=2; 5=3; 7=4; 9=5, so the middle "4" cage can be a 7 or an 8 in this example).

Additionnal rules:

• Each main diagonnal must contain the digits 1-9 once.
• There are greater-than symbols on the grid, where the biggest digit must be placed on the open end.

Note : It is possible for a cage to contain two digits with the same "value": because a grey 6 counts as a "3" doesn't mean you can't also place a 3 in the cage !
