Normal sudoku rules apply.
Pointers: Digits inside caged cells are cloned in the general direction of the pointer. Digits adjacent to the pointers' legs show how far the cloned digit is:
-A Vertically adjacent digit indicates how many rows above or below the caged digit's clone is from the cage itself.
-A Horizontally adjacent digit indicates how many columns left or right the caged digit's clone is from the cage itself.
-!!Cages only serve an aesthetic purpose!!
EXAMPLE:
Let's look at the R8C5 cell.Let the digit in that particular cell be 1. It has a pointer that's pointing north-west. For that reason we need to look at the cells directly above (R7C5) and to the left (R8C4) of the cage. If the digit above the cage is a 4 and the digit to the left of the cage is a 3, then we know that the cloned 1 has to be 4 rows above and 3 columns to the left of the cage. So if we count 4 rows up and 3 columns left of R8C5 or calculate R(8-4)C(5-3) we can figure out that the cloned digit resides in R4C2.
Not all cages and pointers are necessarily given.
