This is my second puzzle with such ruleset, the previous one can be found by clicking on this link.

Rules:

• Normal sudoku rules apply.
• Mod-ified killer cage rules apply: numbers in cages must not repeat. In each N cell cage the sum of the digits modulo N must be equal to the number given in the top left.

In other words, the sum of all the digits in cage can be represented as N*k+c, where N - number of cells inside the cage, k - integer, c - clue given in the top left. For example a 3 cell cage with 0 as the clue could be 1, 2, 3 or 3, 6, 9 etc.
Note: the cages are cosmetic, so f-puzzles won't scream at you if your math bad.
