Hmmmm, this looks familiar. Where have I seen this smattering of salt and pepper dots on a grid before🤔 . I'm in the correct channel, right?

Hold the phone☎️ , that's not a sudoku is it!? Of course not! What do you think this is, GAS? No, you may be surprised to find out that some variants you know and love had their origins BEFORE sudoku. Even before logic puzzles, kropki was a strategy game too! What a rich history for dots when it comes to brain teasers

Today's GAPP is a Kropki puzzle!

Rules: Place numbers in the grid where each cell in each row and column is a different number. Numbers used are from 1 to the length of the rows and columns (1 - 7 for this puzzle). Cells separated by a white dot contain consecutive digits whereas cells separated by a black dot contain digits with a 1:2 ratio. All kropki (dots) are given, meaning that there IS a negative constraint.

This should be familiar to sudoku solvers and pencil pencil solvers alike! 🙂
