Normal sudoku rules apply, using the digits 0-8 instead of 1-9.
In rows 2-8, the 3-digit number in the pill multiplied by the digit in column 1 must result in the same product, i.e.
r2c1 x r2c3~5 = r3c1 x r3c5~7 = r4c1 x r4c7~9, etc.
Digits separated by a white dot must be consecutive. Not all dots are necessarily given.
