Normal sudoku rules apply.

Any two cells separated by a king's move (in chess) cannot contain the same digit.

Digits along a line must be dominos summing to 10

just to be clear.. cell 1-2 of the line sum to 10 and cell 3-4 sum to 10 etc...

Digits cannot repeat within a cage.

Cage totals equal the the highest digit in the cage x2, or in other words the rest of the digits must equal the highest digit of the cage, (see example below).
