This puzzle made me smile. I got this idea of triomino (Which seems to exist already---see comment section) from a puzzle by Full Deck and Missing a few card. I made two versions of this puzzle with slightly different ruleset. This is the second version of the puzzle.

Have fun and Happy Solving!!


===Rules for this puzzle:===

Normal Sudoku rules apply.

Triomino: The sum of the digits in (each of) every possible ‘I’ shaped triominoes (Orthogonal or diagonal) is divisible by 3. (example below)

Dutch Whispers: Digits don’t repeat along the two marked diagonals. Additionally neighboring digits differ atleast by 4 along these diagonals.

The question mark clue act both as X-sum and Numbered room clues.

Explanation of the rules:

I Triomino: Continous connection of three cells (orthogonal or diagonal) in the shape of I.

For example: R1C3, R1C4,R1C5 forms a horizontal triomino. R6C6,R7C6,R8C6 forms a vertical triomino. R4C4,R5C3,R6C2 forms a digonal triamino. R6C6,R7C7,R8C8 forms another diagonal triomino. The sum of the digits in each such individual triaminos is divisible by three

Xsum: Xsum clue gives the sum of the first n digits, where n is the first digit.

Numbered room: A numbered room clue x is the digit to be placed in the n’th cell, where n is the digit in the first cell.

If you find this version difficult, place a two-cell thermo (bulb at R6C6 and tip R5C5) and solve
