This puzzle was set for one of Scojo's Setting Saturday Prompts. The theme for this prompt was the number 2, celebrating Scojo's 2nd anniversary of streaming on Twitch. This is a follow up to a puzzle I made for an earlier prompt called Useless Twos

Each row, column & 3x3 box must contain the digits 1-9.

If the end cell on a green line contains the digit X and the next cell along the line contains the digit Y then the cell at position X on the line must contain the digit Y.

This rule applies separately starting at each end of the line counting the end of the line as position 1, the next cell along as position 2, etc...

Note that the digit Y may also appear elsewhere on the line.

The ratio of digits in cells separated by a black dot is equal to the number in the dot.

Values outside the grid give the sum of all the digits sandwiched between the 1 and 9 in the row or column.
